Frequently Asked Questions
Everything you need to know about using Underpriced AI to identify, price, and sell your items.
Getting Started
What is Underpriced AI?
Underpriced AI helps resellers identify items from a photo, see what they recently sold for, and write listings for eBay, Poshmark, Mercari, and other marketplaces. Snap a photo and get a price, the recent sales behind it, and a ready-to-publish listing in seconds.
How do I scan an item?
Take a photo with your phone camera or upload an existing image. Our AI identifies the item, searches real-time sold data across eBay, Poshmark, Mercari, and other platforms, and returns a detailed valuation with price range, comparable sales, and a listing-ready title and description.
Do I need to connect or set up my camera?
No - there's nothing to pair or connect. On the scan screen, tap "Photo" and it uses your phone or computer's built-in camera right in the app. The first time, your browser or phone will ask permission to use the camera - tap Allow. If the camera doesn't open or you see a black screen, that's almost always a blocked permission: re-enable camera access for our site in your browser or phone settings, or just tap "Upload" instead to pick a photo you already took. The iOS and Android apps give the smoothest camera experience.
Can I add more than one photo of an item?
Yes, and you should when it helps. A single scan accepts up to 12 photos of the SAME item (for example the front, the back, a label, or a maker's mark). It still counts as just one scan no matter how many photos you add, and the extra angles make identification and pricing noticeably more accurate. So to capture the front and back of something, add both photos to one scan rather than scanning twice. When two or more photos are added, the scan page asks "One item, or scan each photo separately?": tap "One item" for several angles of the same thing (1 scan), or "Each photo is a different item" to scan each photo as its own item (1 scan per photo).
What should I photograph when scanning clothing items?
For clothing, take a clear photo of the item laid flat or on a hanger in good light. For best accuracy, also include the brand tag and the size/care label. These help us identify the exact item and match it to the right recent sales. You can add up to 12 photos to one scan (for example the garment, the brand tag, and the size tag) and it still counts as a single scan. The first three are what the AI reads; the rest are saved to the item and go onto your listing.
Do I need to download an app?
Underpriced AI works in your browser on any device - no download required. We also offer an iOS app on the App Store, an Android app on Google Play, and Chrome and Firefox browser extensions for scanning items while browsing online listings.
Is there a free scan or free trial?
Your first scan is free, with no credit card required, and it is the full result: the AI identification, the exact price, the verified recent sales behind it (what resellers call sold comps, with clickable links), and save-to-inventory. Nothing is held back. After that, pick a plan (starting at $5/month for 30 scans) or a scan pack with no subscription (from $3 for 5 scans). Both include pricing, listing (eBay and Bonanza publish directly; for Poshmark, Mercari, Facebook and others our desktop Chrome extension fills the form and on a phone we copy each field for you to paste), inventory, and profit tracking. Sellers can also earn free scans instead of paying, once each: save your first find (+2), connect your eBay account (+5), publish your first listing (+5), and mark your first sale (+5). These bonuses go to free and scan-pack accounts; plan subscribers scan against their monthly allowance.
Can I scan a barcode instead of taking a photo?
You usually don't need to. When a photo shows a book's ISBN or a CD or record's barcode, the scan reads it on its own: we look the code up (Google Books for books, Discogs for music) and use that exact edition when it matches what the AI sees in the photo. If a book or record comes back with only a few sales, the result offers "Scan its barcode" so you can scan the exact edition, and it is priced from real sold listings, exactly like a photo scan. For everything else (clothing, collectibles, electronics, housewares) a clear photo works best.
Can I scan multiple items at once?
Yes - use Batch Scan to do up to 10 different items at once (one photo each). If several different items are in ONE photo, you get one price for the whole group, as a lot or set, not a price per item; take one photo per item when you want each priced. It's built for clearing a pile fast: add up to 10 photos, tap "Each photo is a different item" when the scan page asks, and we identify and price each item separately. Each item counts as its own scan toward your limit. (This is different from adding several photos of the SAME item to one scan, which still counts as a single scan - see above.)
How do I move a scanned item into my inventory?
You usually don't have to - when you scan an item on a paid scan, it's saved to your inventory automatically, so there's nothing to move. To find your scanned items, open Items (in your bottom bar or under More). If a specific scan isn't there (for example one you discarded), open it from Scan history (under More) and tap Save to inventory. If by 'dead pile' you mean items you've saved but haven't listed yet, those are already in your inventory, and Sell (in your bottom bar or under More) gathers them under Ready to list. The next step is to list them: publish to a connected eBay account, or for Poshmark, Mercari and others use our desktop Chrome extension, or on a phone the copy kit that copies each field for you to paste.
How do I remove items I scanned but didn't buy?
Every scan saves to Items on its own, so items you passed on pile up unless you clear them. On the scan result, tap Didn't buy it beside the List button: the item leaves your Items, Undo in the message at the bottom keeps it for a few seconds, and the scan stays in Scan history, where you can save it again later. Already left the result? On Items, tap Remove (the X) on the item's row in any view. It is archived at once, Undo brings it back, and archived items also wait under the Archived filter. Both work on every plan. Neither is offered on an item that is listed, scheduled or sold: open that item and use More actions instead, so a live listing is never taken down by accident.
How do I get started?
Sign up and your first scan is free, with no credit card, and it shows everything: the item ID, the exact price, and the real recent sales behind it. Keep going with any plan or a $3 five-scan pack. Every plan includes pricing, eBay listing, cross-listing help (the desktop Chrome extension fills other marketplaces' forms, and on a phone we copy each field for you to paste), inventory, and profit tracking. Pro Plus and above add inventory tools, analytics and the estate and yard sale finder.
Can the support assistant look at a screenshot?
Yes. In the assistant at underpricedai.com/contact, attach one screenshot (JPG, PNG or WebP) with your message and it will read what is clearly visible, for example an error message or a billing line. It will not guess at text it cannot read. A screenshot is for support questions; to get a price for an item, use Scan (Take Photo or Upload) so the photo goes through the pricing engine.
Where is Underpriced AI located?
San Jose, California. Underpriced AI is a small, founder-run software company, so there is no storefront to visit; the business address is 1750 Meridian Ave #5422, San Jose, CA 95150, and support is handled by email and the assistant at underpricedai.com/contact.
Is it possible to speak with or contact a representative?
Yes. Open the assistant at underpricedai.com/contact and tell it you need a person. A box appears under the chat: leave the email you signed up with, add a note if you like, and tap Send to the team. Your conversation goes to our support team, who reply by email. You can also email support@underpricedai.com from the address on your account. Nothing reaches the team until you send the box or the email, so use one of them rather than waiting in the chat.
Pricing & Accuracy
How accurate is the AI pricing?
Read the range, not the number in the middle. Here is the honest reason. We measured how far apart genuinely identical items sell for, using sales an AI judged to be the same item in the same condition: the middle half of them spread across about 38% of their typical price. The same object, different buyers, different days. So no tool, ours included, can tell you what YOUR item will fetch to the dollar, and any tool that shows a bare confident number is hiding that from you. What we do instead is set the range from that measured spread, so it contains the actual sale price about eight times in ten, and re-check it every week against sales we did not price. Every scan, the free one included, lists the comparable sold listings behind it with clickable links, so you can check our work in one tap. That is enough to answer the question you are actually asking in the aisle, which is whether the item is worth more than the price on the tag, not whether it is worth $92 or $105. The point estimate is a starting position. Accuracy depends on photo quality and how common the item is; add a second angle or a maker's mark for rare pieces, and cross-check the recent sales for anything high-value.
What happens if a pricing source is down or has never seen my item?
The scan moves down a ladder instead of giving up. For US and UK scans we call a specialist sold-price API first; if that call fails, a second, independent service runs the same search (for US scans). In Canada, Australia, Germany, France, Italy and Spain that second service is the first call, in your own currency. If the item was described too specifically to match anything, we retry with just the words that matter, which is the single biggest cause of an empty result. After that we fall back to our own archive of over a million recorded sales, so an outage still returns a real comparable sale rather than a guess. If every source genuinely comes up empty we say so and label the estimate as AI-only, rather than pretending a number is backed by sales that do not exist.
Where does the pricing data come from?
From real sold prices, meaning what items actually sold for rather than what someone is currently asking, drawn from whichever source is best for the item. For US and UK scans a specialist sold-price API is the first call, with an independent backup service behind it for US scans when that call fails (in Canada, Australia, Germany, France, Italy and Spain that service is the first call), and our archive of over a million recorded sales as the floor. Category specialists are added where they genuinely beat the general sources, and we retire them when they stop earning their place, so the exact list changes over time. We also check active listings to gauge current supply and saturation. Because it is a ladder rather than one fragile source, your pricing keeps working when any single site goes dark.
How is this different from checking eBay sold listings manually?
Manual research takes 5-10 minutes per item and stops at a number. Underpriced AI does the research from one photo, across eBay, Poshmark and Mercari plus whichever category specialists currently beat those for the item, and shows you the sold listings so you can check it. Then it does the part manual research never does: it writes the title, description and item specifics, publishes to eBay from the app, fills other marketplaces' listing forms with our desktop Chrome extension (or copies each field for you on a phone), and tracks the item until it sells. Worth it? Now sell it.
Can the AI identify any item?
The AI works best with branded items, electronics, collectibles, vintage goods, clothing, and common household items. Very obscure, handmade, or one-of-a-kind items may get a more general identification. Clear, well-lit photos - and adding multiple angles to one scan - dramatically improve accuracy.
Is there a confidence score on my results?
No percentage score, on purpose: no single number reliably tells a tight price from a loose one. Every scan gives you a range calibrated to hold about 8 in 10 real sales, the sold listings behind it with links, and a plain note next to the price when the category or the matching sales run wide. Every week we measure how often the range really held, on sales we did not price, and publish that share at underpricedai.com/accuracy.
Does Underpriced AI show a sell-through rate (how fast an item sells)?
Yes. On a scan result, open Competition: beside Listed now and Sold recently it shows how fast the item sells, as Sells fast, Sells steadily or Slow mover with the share of similar listings that sell within about a month (the tile is labelled How fast it sells). On a saved item it is the Sell-Through Rate in the Market Saturation box. It is the share of recent eBay listings for the item, sold plus still for sale, that ended in a sale; when there are too few recent sales it uses the typical rate for the category. The price options also include a Sells fast price, a lower price for a quicker sale. Your own sell-through by category, from the items you have sold, is in the analytics dashboard on Pro Plus and above.
Why do you show 'sold' and 'asking' prices separately?
Because they're very different numbers. 'Recently sold' is what buyers actually paid - that's what your estimate is built on. 'Currently listed' is what other sellers are asking, which is often higher than items really sell for. We show both so you can see the gap, and when listings are asking noticeably more than things sell for, we flag it right on the result. Your suggested price follows real sales, not wishful asking prices.
Can I re-check an item's price later?
Yes, and it's free. Open Scan history (under More) and tap 'Get price' on a past scan to re-run it against today's recent sales, which is handy when you're about to list something you scanned a while ago. It doesn't use a scan. Each scan can be re-checked once every 8 hours. On Pro Plus and above you can also select several items on Items and choose 'Refresh prices'.
Can I correct what the AI identified?
Yes. Open the item from the Items page and edit the title, brand, condition, and description fields directly - just type into the form fields. Those details flow into the listing we generate, so your title and description come out more accurate. To re-run the price using your corrections, tap 'Re-analyze' (the button says 'Use 1 Scan & Re-analyze' - it costs 1 scan because we re-run the AI with your edits). If you already know the condition before you scan, open 'Add brand or condition before scanning' on the Scan screen and type or paste it into the Condition box: the first price then uses sales in that condition and you skip the second scan. Notes typed into the description on their own don't automatically re-price the item; Re-analyze is what flips the valuation to reflect your edits. On some less certain results for pottery and glass, jewelry, and antiques, the scan result also asks "Is it one of these?" and shows a few real eBay listings that look like your photo: tap one only if it's the same piece and we re-price yours from sales of that exact item, or tap "None of these" and say what it is. That check is free and doesn't use a scan.
Does the AI learn from my corrections?
Your inputs shape your own results - details you add, like exact dimensions or condition, are used to identify and price that item more precisely, and your saved corrections improve the listings we generate for you. What we don't do is quietly retrain a global model on your data in the background. If you spot an identification that's consistently off, tell us - that feedback is how we improve the system deliberately.
My price shows the wrong currency or country's marketplace (e.g. USD / ebay.com when I'm not in the US). How do I change it?
The currency and marketplace your prices use come from the Country set on your account, not from your phone or browser. Change it in Settings: open Settings, find the Country field near the top of your profile, pick your country, and save. That switches your prices to the matching eBay marketplace, currency, and shipping defaults (for example, changing to the UK moves you to eBay UK in GBP). If your account Country and your actual location don't match, Settings also shows a small prompt offering to update it for you. Supported countries include the US, UK, Canada, Australia, Germany, France, Italy, Spain, Netherlands, Belgium, and Mexico; if yours isn't listed, prices default to the US marketplace in USD.
Plans & Billing
What plans are available?
New subscribers can pick from six paid plans: Starter ($5/month, 30 scans), Pro ($15/month, 100 scans, plus automatic price drops and overnight listing drafts), Pro Plus ($29/month, 240 scans with inventory tools and the analytics dashboard), Business ($59/month, 550 scans), Power ($99/month, 1,000 scans), and Scale ($199/month, 2,500 scans included then 12 cents per scan after, so you never hit a wall) for full-time sellers. Business, Power and Scale include everything in Pro Plus. Annual billing saves about 20% (Scale is monthly only), and unused plan scans carry over one month, up to one month's allowance. Without a plan, scan packs (5 to 250 scans, from $3) never expire. On a plan, top-up scans keep you going past the plan's allowance: scans past your plan are 25 cents each, billed monthly to your card (turn it on in Settings, Subscription). Every scan runs on Claude Opus 5.5, one of Anthropic's most capable vision models. All plans include AI identification, real-time valuations, listing generation, and eBay integration.
What counts as a scan?
Each time you analyze an item - whether by taking a new photo, uploading an image, or re-analyzing a saved item - it counts as one scan toward your monthly limit. Adding multiple photos of the same item to a single scan still counts as just one scan, however many you add. Viewing previously saved scan results does not use a scan.
Does deleting a scanned item or its photos refund the scan it used?
No. Scans are counted at the moment the photo is analyzed, not by whether you keep the item afterward. Deleting a scan, an item, or any of its photos does not add a scan back to your monthly allowance or pack scans. If you accidentally created duplicate scans of the same item, you can still delete the extras to tidy up your inventory. It just will not change your scan count.
Can I change or cancel my plan?
Yes, and it's self-serve: go to Settings → Subscription (underpricedai.com/settings#subscription). You can upgrade (with prorated credit for the unused portion of your current cycle), downgrade, pause, or cancel yourself in a couple of taps. Pausing (for 1, 2 or 3 months) stops the charges while keeping your items, listings and history, and your plan resumes on its own. If the pause skipped a monthly bill, your plan restarts the day it resumes: you pay the plan price that day and your next bill is one month later. If you tap Resume now early, Settings shows the amount first and a declined card leaves the plan paused. When the pause ends on its own, the card on file is charged that day with no extra step, and a declined card is handled like any missed payment, with the usual retries. If you tap Cancel or change plan and tell us you're not ready to sell yet, that pause is the first thing offered. If you cancel, it stops the renewal and you keep access through the end of your current billing period. Your saved scans and data are preserved either way.
How does switching to a cheaper plan work?
Go to Settings → Subscription (underpricedai.com/settings#subscription), tap Cancel or change plan, and pick a smaller plan (monthly plans; a yearly plan keeps every feature until it renews); you can jump straight to any cheaper plan, not just the next one down. If the scans you've used this month fit inside the smaller plan, the switch happens right away and the unused part of this month is credited to your next bill. If you've already used more scans than the smaller plan includes, you keep your current plan and all its scans until your renewal date, then move to the smaller plan, and nothing changes on your card until then. Either way your items, listings and history stay, and Settings shows the date your plan changes. Changed your mind? "Keep" your current plan from the same place.
What happens to my plan scans and pack scans when I cancel?
Cancelling stops the next renewal; you keep your plan and its scans until the end of the period you've paid for, and Settings shows the date. If your last renewal didn't go through (the plan is past due) and it's the only bill outstanding, cancelling ends the plan today instead and clears that unpaid bill, so nothing more is charged or retried. Then: monthly plan scans and any carried-over scans end with the plan. Scans you bought in a pack, and bonus or referral scans, never expire, so they stay on your account and keep working after the plan ends. Your items, listings and history stay too. Changed your mind before the end date? Tap Keep my plan in Settings → Subscription and it renews as normal, with nothing charged until then.
What's your refund policy?
Your first scan is free so you can try Underpriced AI before paying. Because of that, monthly plans and scan packs are non-refundable - but you can change or cancel your plan anytime yourself in Settings → Subscription (underpricedai.com/settings#subscription), and cancelling keeps full access through the end of the period you've paid for, with your scans and history preserved. One exception in your favor: if you moved to a cheaper plan mid-cycle and cancel or pause before the credit for the unused time has been applied to a renewal, that credit is refunded to your card automatically when you cancel or pause. If a charge was our mistake, the refund is in full with nothing kept. Annual plans have a 30-day money-back guarantee: ask for your refund within 30 days of buying or renewing (the refund ends the plan; canceling alone only stops the renewal): your money back, less the card processing fee, if you haven't scanned with your plan, or, if you have, everything except each month you've started at the monthly price plus any tax (and the fee) (annual plans bought from September 9 through October 15, 2026 get the whole charge back within 30 days either way). Renewals on or after October 16, 2026 follow this rule too, and each renewal starts a new 30 days. Canceling inside the 30 days holds your place if you ask within 30 days of canceling. For annual plans bought from September 9 through October 15, 2026, canceling within the 30 days keeps your refund open with no later deadline; you still ask for it. A refund ends the plan when it is issued, and Settings, Subscription, Cancel or change plan shows the amount first, or tells you a person will confirm it. After 30 days, cancelling stops the next renewal and you keep full access to the end of the year you paid for, with no partial refund (annual plans bought before September 9, 2026 keep their original unused-full-months refund on request). Not logged in? Use the Cancel Subscription page at underpricedai.com/cancel-subscription for a one-click cancel link, no sign-in needed. For a charge you don't recognize, contact us at underpricedai.com/contact with the email you signed up with.
I accidentally upgraded my plan by mistake - can I get a refund or reversal?
An in-app upgrade takes effect immediately and charges a prorated amount for the rest of your billing cycle, so an accidental tap can result in a charge. Monthly plans are non-refundable; an annual plan is covered by the 30-day money-back guarantee (ask for your refund within 30 days of buying or renewing (the refund ends the plan; canceling alone only stops the renewal): your money back, less the card processing fee, if you haven't scanned with your plan, or, if you have, everything except each month you've started at the monthly price plus any tax (and the fee)). To stop any further charges, downgrade or cancel yourself in Settings → Subscription (underpricedai.com/settings#subscription) - you keep access through the end of the period you've paid for. If you see a charge you don't recognize, contact us at underpricedai.com/contact with the email you signed up with and we'll look into it.
I'm not logged in and want to cancel - what do I do?
You don't need to log in. To cancel, use the Cancel Subscription page at underpricedai.com/cancel-subscription - enter the email on your subscription and we email you a one-click cancellation link, no sign-in required. It stops the renewal and you keep access through the end of the period you've paid for. Monthly plans and packs are non-refundable. Annual plans have a 30-day money-back guarantee: ask for your refund within 30 days of buying or renewing (the refund ends the plan; canceling alone only stops the renewal): your money back, less the card processing fee, if you haven't scanned with your plan, or, if you have, everything except each month you've started at the monthly price plus any tax (and the fee) (bought from September 9 through October 15, 2026: the whole charge either way). Canceling inside the 30 days holds your place if you ask within 30 days of canceling. For annual plans bought from September 9 through October 15, 2026, canceling within the 30 days keeps your refund open with no later deadline; you still ask for it. After that, cancelling stops the next renewal and you keep access to the end of the year you paid for, with no partial refund (annual plans bought before September 9, 2026 keep their original unused-full-months refund on request). For an annual refund, any other support, or a charge you don't recognize, ask the assistant at underpricedai.com/contact (say you need a person and leave the email you signed up with in the box that appears) or email support@underpricedai.com with that email.
What happens when I run out of scans?
When you reach your monthly scan limit (your plan's allowance plus any scans carried over from last month), you can buy a scan pack, turn on top-up scans in Settings (scans past your plan are 25 cents each, billed monthly to your card), or upgrade to a higher plan. Pack scans never expire and carry over month to month.
Do unused monthly scans roll over?
Yes, on a paid monthly or yearly plan. Scans you don't use in a month carry over to the next month, up to one month's allowance, and carried scans are used first. A carried scan lasts one extra month, so it doesn't pile up past that. For example, on a 30 scan plan, if you use 18 this month, next month you have 30 plus 12 carried over. Carried scans end when your subscription ends; they aren't turned into pack scans. Settings shows the split, for example "30 this month + 12 carried over". Pack scans are separate and never expire.
How do I check how many scans I have left?
Go to Settings and open the Subscription section. It shows your total scans available - your monthly plan allotment, any unused plan scans carried over from last month, plus any pack scans (which never expire and carry over month to month). That's the live count for your account.
How much do scan packs cost?
Scan packs are one-time purchases with no subscription required: 5 scans for $3, 15 scans for $7, 30 scans for $12, 50 scans for $18, 100 scans for $32, and 250 scans for $70. Bigger packs cost less per scan (from 60 cents down to 28 cents each), and pack scans never expire; they carry over month to month. If you scan regularly, a subscription is the better per-scan deal; packs are built for occasional use or topping up when you hit your plan's limit.
I bought a scan pack through an AI assistant (ChatGPT, Perplexity, Claude). Where are they?
Scan packs bought through an AI assistant are delivered by Stripe to the Underpriced AI account that owns the email you used at checkout. If you already had an account under that email, the scans are on it now (Settings shows your total). If you did not, we created one for you and emailed a welcome message plus a set-password link to that address, so sign in with that email. Used a different email at checkout than the one you sign in with? Contact us at underpricedai.com/contact with both addresses and the Stripe receipt and we will move the scans. Subscriptions cannot be started through an assistant; those begin at underpricedai.com/pricing.
Do you have a referral program?
Not anymore. The invite a friend program ended on September 29, 2026, and its last bonuses landed by October 29, 2026. Bonus scans you already earned stay on your account. Referral links no longer earn anything.
Why am I asked to verify my phone number by text at checkout?
That prompt comes from Stripe Link, our payment processor, not from Underpriced AI. Stripe offers to save your card by verifying your phone via text so future checkouts are faster. It is completely optional and skippable - just enter your card details directly to finish. We never require phone verification, and we do not see or store your phone number from that step.
Selling & Listings
How do I list on other marketplaces like Poshmark, Mercari, Facebook Marketplace, Depop, Vinted, Etsy or Whatnot?
eBay and Bonanza listings post directly from inside the app (Discogs too, for records), on any device. Poshmark, Mercari, Facebook and the others have no way for us to post for you, so we help you fill their form instead. On a computer, use our free Chrome extension (desktop Chrome or Edge): open the item, pick the marketplace, click "Copy & Open", and the extension fills that marketplace's listing form with your title, price, description and photos. You review the details, pick a category, and click Post. On a phone, open the item, pick the marketplace and tap "Copy it step by step" (Poshmark, Mercari, Facebook, Depop, Vinted and OfferUp): it shares or downloads your photos first, then gives you one Copy button per field in the order that marketplace's form asks, and an Open button for the marketplace. You paste each field and post it yourself in their app. On a phone, the iPhone and Android apps (version 2.4.0 and up) have "Open the form with my listing": it opens the marketplace's form inside the app and fills it for you; on Android, Firefox with our add-on fills it too. You pick the category and post.
Can I reorder photos or choose the main photo?
Yes, on any device. Open the item's page, tap the photo you want to move so it fills the large view, then open the three-dot "More actions" button in its top-left corner: "Make main photo" sends it to the front, and "Move left" and "Move right" shift it one place at a time. On a computer you can also drag the thumbnails into the order you want. The first photo is the main one: it leads the eBay listing and the paste kit for other marketplaces, and it is the image buyers see in search results. You can also add more photos there before you publish.
Can I import my existing inventory or current listings into Underpriced AI?
Yes for eBay, and you need to be signed in first (sign up free if you haven't; your first scan is free). Connect your eBay account, then go to More > Settings > Marketplaces, and in the eBay card tap "Import Active Listings" and then "Import". It brings in each active listing's title, description, price and photos as items you can manage here, and they keep the shipping and return terms they already have on eBay. Running it again (the button then says "Re-import") skips listings you already imported, so it is safe to repeat. There is no spreadsheet or CSV import, and no import from other tools or marketplaces. To add other items, use "Add without scanning" on the Items page: your own photos and details, no scan used, and you can price it later.
Which marketplaces can I list on?
You can publish listings directly to eBay (US, UK, Canada, Australia, Germany, France, Italy, Spain, Netherlands, Belgium) and Bonanza from inside the app, and records to Discogs. For the other marketplaces, install our free Chrome extension (desktop Chrome or Edge) and it fills in the listing form for you; you review the details and hit Post. It works with Facebook Marketplace, Poshmark, Mercari, Depop, Whatnot, Vinted, OfferUp, Etsy, District, Craigslist, 1stDibs, and Ruby Lane. For District the item page can also download a CSV in District's bulk-import format for you to upload. On a phone, or if you'd rather not install anything, the item page copies each field for you to paste: "Copy it step by step" for Poshmark, Mercari, Facebook, Depop, Vinted and OfferUp, and tap-to-copy buttons plus a photo download for the rest. We never post to those marketplaces for you. On a phone, the iPhone and Android apps (version 2.4.0 and up) have "Open the form with my listing": it opens the marketplace's form inside the app and fills it for you; on Android, Firefox with our add-on fills it too. You pick the category and post.
How do I cross-post the same listing to multiple marketplaces?
Two ways, depending on the marketplace. eBay (10 countries) and Bonanza publish directly from the app: check the listing we wrote and publish it, no retyping and no extension needed. For everyone else, install our free Chrome extension (desktop Chrome or Edge): open any saved item and click to cross-list, and the extension opens that marketplace's create-listing form with your title, price, description, and photos already filled in; you review, pick the category, and hit Post. It works on Facebook Marketplace, Poshmark, Mercari, Depop, Whatnot, Vinted, OfferUp, Etsy, District, Craigslist, 1stDibs, and Ruby Lane. It runs entirely in your browser, so we never see your marketplace logins. Because it's a browser extension, the form filling works on a desktop computer (Chrome or Edge), and on an Android phone in Firefox with our free Firefox add-on; Chrome on a phone runs no extensions. Otherwise, on a phone, open the item and tap "Copy it step by step": we copy each field in the order that marketplace asks and you paste it into their app and post it yourself.
Can I edit the AI-generated listing?
Absolutely. The AI generates a title, description, and suggested price as a starting point. You can edit every field before publishing. Many sellers use the AI output as-is, while others customize it to match their selling style.
How do I remove a photo I uploaded from an item?
Open the item from your Items list and tap the thumbnail of the photo you want gone, so it shows in the large view. In the photo's top-left corner there is a row of small buttons: tap the three-dot "More actions" button and choose "Delete", then confirm. The same menu can replace that photo with a new one or download it. This removes only that photo; the item and its other photos stay exactly as they were, and deleting the whole item is a separate action from the item's own menu. The buttons are always visible on a phone and appear when you hover on a computer, and the steps are the same on web, iPhone and Android.
Safari says "the file doesn't appear to be a valid download file" when I use Download All Images. What do I do?
That was a bug on our side in Safari, fixed on 2 November 2026. "Download All Images" is on the item page under the photos, shows the photo count, and saves every photo on the item one file at a time. Safari refused the files because the download link was withdrawn before Safari had read it. Each photo now downloads straight from our server with a short pause between files, so Safari on a Mac saves all of them, and Chrome, Edge and Firefox do the same. On a phone or tablet the share sheet opens instead, so the photos go into Photos or straight into the marketplace app. If you still see the message, reload the page once so the browser picks up the new version. To save a single photo, tap it so it shows in the large view, then use the three-dot "More actions" button in its top-left corner and choose "Download". The phone copy kit ("Copy it step by step") also shares or downloads your photos before the fields.
I'm on my phone's browser (Safari or Chrome), not the app. How do I list on Depop, Poshmark, Mercari or another marketplace?
In a phone browser, open the item, pick the marketplace and tap "Copy it step by step" (Poshmark, Mercari, Facebook, Depop, Vinted and OfferUp). It shares or downloads your photos, then gives you one Copy button per field in the order that marketplace's form asks, plus an Open button. You paste each field and post it yourself. "Open the form with my listing" is only in the iPhone and Android apps (version 2.4.0 and up), not in a mobile browser. Chrome on a phone cannot run extensions. On Android, Firefox with our free add-on can fill the form. On a computer, use the Chrome or Edge extension's "Copy & Open". You always pick the category and post it yourself.
Can I remove the background from my item photos?
Yes, on every plan, and it does not use a scan. Open the saved item, and in the photo viewer tap the eraser button in the photo's top-left corner (always visible on a phone, shown on hover on a computer) labeled "Remove background". The AI cuts out the item and places it on a plain white background in a few seconds. Your original is kept: a "Restore original" button appears on that photo to undo it. It works per photo, including photos imported from eBay. The Rotate left and Rotate right buttons next to it turn a photo that came out sideways. There is no crop or filter tool, so make those edits on your device first. If eBay seems to crop your photo on publish, that is the separate eBay Photo Style setting in Settings (choose "Fit whole item").
Can I list on eBay as an auction instead of fixed price?
Yes. Fixed price is chosen for you when you list on eBay, and Auction is one tap away in the listing format choice. Auction opens up a start price, duration (1/3/5/7/10 days, default 7), and optional reserve and Buy It Now. The start price defaults to 50% of the estimated value since low starts historically attract more Watchers and bids, but you can change it to anything you want.
Do I need eBay business policies (shipping, returns, payment) before I publish, and where do I set them up or change them?
On eBay US, UK, Canada, Australia and Germany you do not need them: if your eBay account has no business policies, each listing carries the shipping and return terms you choose in the publish form. On eBay France, Italy, Spain, the Netherlands and Belgium you need all three (shipping, payment and return) before you can publish there. If your account already uses business policies but one of the three is missing, the app tries to create the missing one when you publish, named "Underpriced AI default payment" or "Underpriced AI default returns", and a shipping one named for its terms ("Underpriced AI shipping, free to buyer" or "Underpriced AI shipping, buyer pays" and the amount; older ones are "Underpriced AI default shipping"), so you can find and edit it on eBay. Policies are created and edited on eBay itself, in Seller Hub under business policies (for eBay US: https://www.bizpolicy.ebay.com/businesspolicy/manage). In the app you only choose which ones to use: More > Settings > Marketplaces, then in the eBay card tap "Manage" next to Business Policies and pick a Shipping Policy, Payment Policy and Return Policy ("Auto-detect" uses the one marked default on eBay, or your first one). After you make or change a policy on eBay, tap "Refresh policies from eBay" in the same card. Your choice applies to listings you publish from then on; listings already on eBay, including ones you imported, keep the terms they have.
Can I connect the eBay account I already use for buying, or do I need a separate seller account?
Use the account you already have; you do not need a new one. Connect it from Settings, and we list through it. If you have never sold on that account, eBay asks you to finish its own seller setup (adding your payout details) before your first listing goes live. That step happens on eBay, once, and is the same for every seller.
Can I end an eBay listing from Underpriced AI?
Yes. Open the item, look for the "End on eBay" button under "Live on eBay." One click ends the listing on eBay directly with no need to go to Seller Hub. Ended listings show a Relist card: one tap brings the listing back live, optionally at a new price. (A relist is a fresh eBay listing, so watchers don't carry over; that's how eBay works.)
Can Underpriced AI lower my prices or write my listings for me?
Yes, on Pro and up, under Settings then Notifications, in Selling on autopilot. Three switches. Drop the price after 14 days: a live fixed-price eBay listing unsold for 14 days moves to the Market price, 14 days later to the Sells fast price, then we stop; it never goes under your cost plus eBay fees when you have recorded a cost, or under the lowest recent sold price (whichever is higher), and we email you each day something moves. It is off until you turn it on. Write my listings overnight: items you kept this week with no listing get an eBay draft written while you sleep (title, description and the Market price), waiting under Sell in Not live yet for one tap each; nothing goes live until you publish it. An item counts as kept once you open it or add a cost, a photo, a tag or a storage spot. That one is on by default on Pro and up. Draft everything I scan: every item you save gets a draft, kept or not, for scanning a whole lot you mean to sell; it is off until you turn it on. Auto-relist of an ended listing is a checkbox at publish time on every plan.
Can I change the price of a listing that's already live on eBay?
Yes. Open the item and you'll see your live listing card with a price field and an "Update price" button: the new price pushes straight to eBay, no Seller Hub needed. There are also one-tap markdown chips (−5%, −10%, −15%) for quick price drops. If you've edited the title or description in the app, a "Push title & description to eBay" button updates those on the live listing too. One eBay rule to know: auctions that already have bids can't change price. eBay refuses that on every tool, not just ours.
Can eBay Best Offers be accepted automatically?
Yes. On your live listing's card, open Best Offer settings to enable offers with two optional thresholds: offers at or above your auto-accept price sell instantly, and offers below your minimum decline automatically, so no more waking up to lowball offers waiting for a response. The offers in between wait for you on Sell, under Live, in Offers: tap Accept, Counter or Decline. Where we have recent sales, each offer says whether it is in the range similar items sold for. Accepting is a sale, so it asks you to confirm first. If that box says Answer eBay offers here, tap Reconnect eBay once; nothing on your listings changes. Fixed-price listings only (eBay doesn't do Best Offer on auctions).
Can I set a Promoted Listings ad rate when I publish to eBay?
Promoted Listings is eBay's own advertising and is set on eBay, not in the app. Listings published from a connected tool open on eBay in the "Revise your listing (with restrictions)" form, where the General promote toggle only applies the rate of the campaign the listing sits in and typing a different percentage flips back. To use a fixed rate such as 3%, open Seller Hub's Advertising dashboard (https://www.ebay.com/sh/ads/dashboard), edit your General campaign, switch the ad rate strategy to a fixed rate, and save. Every listing in that campaign then follows it. Or turn on Promote on eBay in Settings or at the publish step: pick one of your running General campaigns and every listing you publish live joins it at that campaign's rate.
Does the app fill in eBay's required item specifics for me?
Yes. When you pick a category and condition, the intake form loads any item specifics or structured condition details eBay requires for that specific category and pre-fills them from your scan when possible (Brand, Model, Coin Condition, Storage Capacity, and so on). You just fill in whatever's still blank and publish. No more "publish, fail, retype" round trips.
Can I schedule a listing to go live later?
Yes. On the publish screen, pick a time (the "Go live at" picker, or tick "Start it later on eBay") and tap "Schedule on eBay". The listing waits in eBay Seller Hub, where you can still edit it, and goes live by itself at that time, up to 21 days out. It is not a draft, and there is no separate save-as-draft-on-eBay button: to keep a listing in the app without sending anything to eBay, use "Save for later". To go live now, tap "Publish on eBay". The time is chosen per listing. There isn't a global default listing time setting that applies to every new listing automatically.
Does the listing include keywords for SEO?
Yes. Listing titles and descriptions are optimized with relevant keywords that buyers actually search for. This includes brand names, model numbers, size, color, condition descriptors, and category-specific terms to maximize visibility in marketplace search results.
Can I share a scan result with someone?
Yes. On any scan result, tap 'Share' to get a public link you can send to a buyer, a friend, or post anywhere. The recipient sees the item, the price range, and the recent sales without needing an account. You can share before or after you list.
How do I change which marketplace my items list to by default, for example eBay instead of Etsy?
Two things decide it, and both are on every plan. (1) In Settings, open "Where do you sell" (underpricedai.com/settings#preferences) and pick every place you sell: eBay, Poshmark, Mercari or another app, Facebook or local pickup, or Not sure yet. If eBay is one of them the app leads with eBay, since we publish there for you; otherwise the copy kit comes first and the eBay suggestions stop. (2) The List button remembers one marketplace: the one you last picked in the "Where do you want to list it?" chooser, or else the one you last listed to through the app, and it names it, for example "List on Poshmark". To change it, tap "Change" or "List somewhere else" next to the button and pick another marketplace; that pick is remembered from then on. The chooser lists the remembered marketplace first, then the places you named in Settings, then eBay, then the rest. eBay is only remembered from your history while your eBay account is connected. There is no other default marketplace setting.
What happens to my listings if I cancel?
Listings already published to eBay or Bonanza stay live on those platforms - Underpriced AI never removes them. Your saved scan data is also preserved if you decide to resubscribe later.
Inventory & Tracking
Can I hide or rearrange parts of Items or the item page?
Yes. On Items, tap 'Customize' under 'Your Items'. On an item, open the More actions menu (⋮) and tap 'Customize this page', or use the link at the end of the page. Each part has a switch to show or hide it and arrows to move it up or down; tap 'Done' to save. Your items list stays at the bottom of Items, and the next step on an item, your scans left and payment notices always show. The item page layout applies to every item, and a part you hid is still one tap away under 'More on this item'. To put everything back, open Customize and tap 'Reset to default', then 'Done'. Your layout is saved on your account, so the phone app and the web match.
Can I track my purchase price and profit?
Yes. When you save a scan, you can record the purchase price, and on any item page the Inventory card at the top holds Purchase Price, Where Found, Purchase Date, and Quantity. The app calculates estimated profit based on the suggested selling price minus your cost and estimated platform fees (eBay, Poshmark, Mercari, etc.). The eBay fee follows the Country on your account: US sellers pay a 13.6% final value fee in most categories, while UK and German private sellers pay no eBay selling fee on domestic sales, so none is taken off. Other countries use the US rate as an estimate, the other marketplaces use their US rates, and you can type over any fee. When items sell on eBay, the actual sale price and fees are auto-synced - no manual entry needed.
What does the Quantity field mean, and why does my title say 'box of 81' when I have 45?
Quantity on the Inventory card is how many identical lots you have to sell, and it becomes the listing quantity when you publish. One box of 81 tiles is Quantity 1. If you have a partial box, say 45 tiles, keep Quantity at 1 and edit the title and description on the item page so they say 45 tiles, partial box. The scan wrote 'box of 81' because that is what the packaging says, and it priced the item as a full box, so tap the price to set your own for the partial lot. Changing Quantity never changes the title, the description or the price.
What is the Sourcing Calculator?
Every scan result has a 'Should I Buy It?' check. Type the price tag and it tells you whether the item is worth buying, with your net profit and ROI on eBay, Poshmark, Mercari and Facebook; add shipping for a closer number. It is made for sourcing in the store: scan the item and know before you pay.
Does Underpriced AI sync with eBay automatically?
Yes. When an item you listed through Underpriced AI sells on eBay, we automatically pull the sale price, marketplace fees, and shipping charges via eBay's Fulfillment API. Your profit calculations update automatically - no manual data entry required.
What is the Ready to list card?
On Sell (in your bottom bar or under More), under Not live yet, the Ready to list card ranks every item you've saved but not yet listed anywhere, so you know what to list first. It scores each item on how long you've owned it, how fast the category sells, the profit potential, and the item's value, and puts the ones costing you most at the top. Each row has a List button that opens the listing form for that item.
Will I be notified if an item's value changes?
Not item by item, and we would rather say so than have you waiting on an email that isn't coming. What you do get is a weekly portfolio email covering what your inventory is worth, what sold, what you listed, the profit you realised, and what's trending in the categories you source. For a fresh number on one specific item, open Scan history (in your bottom bar or under More) and tap 'Get price' on its scan, which re-runs it against today's recent sales on the spot, free. You can turn the weekly email off under Settings, Notifications.
Where do I see which marketplace an item sold on?
The marketplace is saved with the sale. When you tap Mark Sold you pick where it sold (eBay, Poshmark, Mercari, Facebook, OfferUp, Craigslist, Whatnot, Depop, Etsy, Vinted, Bonanza, local or other), and a sale on your connected eBay account is recorded as eBay automatically when it syncs. You see it in the confirmation right after you mark the item sold, and the Items export (the Export button on Items, every plan) has a "Listed On" column that lists the marketplaces on each item, plus the sale price, date, fees and net profit. The Items list, the item page and the Sold tab under Sell do not show a "sold on" label yet, so the export is the place to look across many items.
How do I download or re-download my inventory as a CSV / Excel file?
There are two ways to export your full item list to a CSV (which opens straight into Excel or Google Sheets), and both are available on every plan: (1) On Items (in your bottom bar or under More), use the 'Export' button in the toolbar. It downloads your items (name, brand, category, value, condition, and more), and it respects any filters you have applied. (2) On the Scan history page (in your bottom bar or under More), use 'Export CSV' to download all of your scans as a CSV (this is the file named 'underpriced-inventory-[date].csv'). You can re-download either one any time - the export is generated fresh each time, so there is nothing to find again; just click the button once more. Note: this is different from the 'Tax Report' on the Analytics page, which is a Schedule C accounting export for tax season, not your inventory list.
Why does Items show only some of my items, and how do I see more than 100?
Items shows 100 items a page: items to list first, then live, then sold, newest first in each. When you have more, a line above the list says which you are seeing (for example Items 101 to 200 of 359), and Previous and Next under the list move between pages. The sort you pick applies across every page. To jump to one item, use the search box or the status, location and tag filters, which look across your whole inventory, not just the page on screen. Export on Items downloads every item as a CSV.
Can I export a tax report?
Yes, on Pro Plus and above. Open Analytics (under More; on lower plans it is not listed there, and underpricedai.com/pricing shows what each plan adds) and click 'Tax Report' to download a Schedule C-ready CSV for the current year. It includes per-item revenue, cost of goods sold (COGS), shipping costs, platform fees, other expenses, and net profit - plus summary totals. This makes tax season significantly easier for resellers.
What inventory features are included?
Pro Plus and higher plans (Business, Power, Scale) include storage locations (organized hierarchically), custom tags for categorization, bulk operations (archive, delete, assign, print labels, refresh prices), and advanced filtering. This makes it easy to manage large inventories across multiple sourcing trips.
How do I record where an item is stored (bin, shelf, room, or a SKU for its location)?
Use Storage Locations (Pro Plus and higher plans). First create your locations under Settings > Inventory Organization > Storage Locations at underpricedai.com/settings/storage (that card shows only on Pro Plus and above). They can nest, for example Garage > Shelf A > Bin 3. Then open any item from Items: the Inventory card at the top of the item page has a 'Storage Location' dropdown and your tags. It saves as soon as you choose. To move many items at once, tap 'Select' on Items, pick the items, and use Actions > Move to location. Items can filter by location. Each item can also carry your own SKU: the Inventory card's 'SKU / custom label' field, with a Suggest button that builds one from the location (Garage > Shelf A > Bin 3 becomes GAR-SA-B3 plus a short code). It prints on barcode labels and goes to eBay as the listing's custom label.
Can I print barcode labels and scan them to find an item?
Yes, on every plan. Open an item and use 'Print label' in the Inventory card, or on Pro Plus and higher plans select several items on Items and choose Actions > Print labels. Pick the Avery 5160 sheet layout (30 labels per letter page) or the 2.25 x 1.25 inch thermal layout for Dymo, Rollo, or Brother label printers, then print from your browser's print dialog. Each label carries a Code 128 barcode of the item's SKU plus the title and storage location; items without a SKU print a short code that works the same way. To find an item later, tap 'Scan label' on Items (on a phone it is under 'More') and point the camera at the label - the item opens.
My barcode label printed only the Underpriced AI logo, or came out blank or cut off. How do I fix it?
A label that printed only the logo was a bug we fixed on October 13, 2026: the app's top bar printed on every page and, on a 2.25 x 1.25 inch thermal label, covered the label itself. The labels page now prints the labels and nothing else, so reload it and print again. If a label still comes out wrong, check the print dialog: for the Thermal 2.25 x 1.25 in layout, choose your label printer and turn off headers and footers (each label is its own page); for the Sheet (Avery 5160, 30/page) layout, set margins to none and scale to 100%. A label with text but no barcode means its SKU could not be turned into a barcode; the code is still printed as text. If it still prints wrong, tell us your printer model, the label size loaded in it, the layout you picked, and your browser, and we will look into it.
How do I undo 'Mark as live' or set an item back to not listed?
Open the item and tap the status badge at the top of the item page (Saved / Live / Sold): it opens a small menu with the status changes. The three-dot menu next to it has the same actions. While an item shows as Live, you will see 'Unlist Item', which sets it back to Saved (not listed) without touching anything on a marketplace. Tapping the 'Analyze' step in the progress bar at the top of the item page does the same thing. This only changes the status flag in your inventory - if the item is actually live on eBay through Underpriced AI, end the listing from the "Live on eBay" card on the item page instead, and the status updates on its own. Sold items have 'Mark as Unsold' in the same menu.
How do I delete an item from my inventory?
Open the item you want removed from Items; you'll find a delete option in that item's actions. On Pro Plus and higher plans, there's also a bulk-delete option under bulk operations if you want to clear several items at once. Deleting is permanent: once removed, the item's photos and valuation history are gone for good.
Is there an analytics dashboard?
Pro Plus and above (Business, Power, Scale) get the full analytics dashboard with revenue and profit reports, category performance analysis, inventory aging reports, sourcing ROI tracking, and tax report exports. This helps you understand which categories and sourcing methods are most profitable.
Platforms & Devices
The app says "Failed to fetch" or my scan won't go through. What should I do?
"Failed to fetch" means your phone or computer lost its connection to our servers for a moment. On a scan, a connection that drops before the photo reaches us never uses a scan: the app retries once on its own, and if that fails too it says "Connection hiccup. Your scan wasn't used." If it says your scan was interrupted after it started, open your Scans list first: if the result is there, the scan went through and it is yours; if it is not there, the scan was not used. Then try again on a stronger connection: switch between wifi and mobile data, or fully close the app or browser and open it again. If it keeps failing, open the assistant at underpricedai.com/contact, attach a screenshot of the message, and say whether you are on the iPhone app, the Android app or a browser.
How do I change the tabs in my bottom bar?
Put the places you open most one tap away. Go to More, then Settings, then Your tabs, and tick the 2 tabs you want between Scan and More: Items, Sell, Scan history, Labels, or Analytics on Pro Plus. It saves as soon as 2 are ticked and the bar changes right away; your other devices pick it up the next time you open the app. To swap, tap the tab you want: it replaces the older of your two picks. Scan always stays first and More always stays last. A tab you don't pick is never gone: it waits under More, so if Sell or Items isn't in your bar, open More and it's at the top. Reset to Scan, Items, Sell puts the original bar back.
How do I close the banner at the bottom of the screen in my phone's browser?
In a phone browser we show a small banner at the bottom of the screen: on iPhone it offers the Underpriced AI app from the App Store, on Android it offers to add the site to your home screen. Tap the X on its right side to close it. Once closed it stays away for 30 days, and after the third close it stops for good. If you see no X, close the tab and open underpricedai.com again: an older version of the banner put its X off the edge of the screen, which was fixed on October 17, 2026. In the iPhone or Android app the banner never shows.
Can I use Underpriced AI inside ChatGPT or Claude?
Yes. We run a connector (an MCP server) that plugs Underpriced AI into Claude, ChatGPT and coding assistants like Cursor and VS Code. Once it is connected you can ask the assistant to price an item, pull the real recent sales behind that price, get a worth-it verdict on a potential buy, or draft an eBay listing, all without leaving the chat. It never publishes a listing on its own; anything it drafts waits for you. It is listed in both the Claude Connectors Directory and the ChatGPT plugin directory, so in either app one tap adds it: claude.ai/directory/underpriced-ai or chatgpt.com/plugins/plugin_asdk_app_6aa6c2b7d6b48191b7c775a81717421d. Setup for other assistants is at underpricedai.com/mcp.
Do you have an API we can build into our own product?
Partly, and it is worth being precise about which part. The MCP server above is a real programmatic interface to the same pricing engine our apps use: price an item from a photo, pull the recent sales behind that price, and a worth-it check against a cost. What it does not have yet is a service-key or machine-to-machine login, which is what a server-side integration inside another product normally needs. It signs in a person through OAuth, so it suits an assistant acting on someone's behalf rather than your servers pricing items on their own. If you are building something that would price at volume inside your own platform, write to support@underpricedai.com with your expected monthly volume and whether you would be sending photos or text descriptions, and Frank will answer directly. We have set up flat per-item volume arrangements outside the standard plans before.
Does Underpriced AI work on mobile?
Yes. The web app is fully responsive and works on any smartphone or tablet. We have a dedicated iOS app on the App Store and an Android app on Google Play, both with native camera integration for the fastest scanning experience.
Is there a Chrome extension?
Yes, for desktop Chrome and Edge, and it does two things. First, scan from anywhere: right-click any product image while browsing online listings, thrift store websites, or auction sites and choose "Scan with Underpriced AI" for a valuation. Second, one-click cross-listing: on any of your items, one click opens the create-listing form on Facebook Marketplace, Poshmark, Mercari, Depop, Whatnot, Vinted, OfferUp, Etsy, District, Craigslist, 1stDibs, and Ruby Lane, and fills the title, price, description, and photos; you review, pick the category, and click Post. It runs entirely in your browser and we never see your marketplace logins.
Can I cross-list to Facebook Marketplace, Poshmark, Mercari, and other marketplaces?
Yes. On desktop Chrome, install our free extension and every item gets one-click cross-listing to Facebook Marketplace, Poshmark, Mercari, Depop, Whatnot, Vinted, OfferUp, Etsy, District, Craigslist, 1stDibs, and Ruby Lane: we open the marketplace's own create form and fill the title, price, description, and photos; you review and click Post, so nothing is ever posted without you. On a phone the extension can't run, so each item page has "Copy it step by step": it shares your photos, then copies every field in the order the form asks, and you post it yourself in the marketplace's app. eBay and Bonanza go further with full direct publishing from inside the app (Discogs too, for records). On a phone, the iPhone and Android apps (version 2.4.0 and up) have "Open the form with my listing": it opens the marketplace's form inside the app and fills it for you; on Android, Firefox with our add-on fills it too. You pick the category and post.
Do you support international sellers?
Yes. eBay integration supports 10 countries (US, UK, Canada, Australia, Germany, France, Italy, Spain, Netherlands, Belgium), and pricing data is localized to your marketplace and currency. Italian users get recent sales from ebay.it in EUR, UK users from ebay.co.uk in GBP, and so on. The identification and listing features work globally regardless of country.
Why does signing up with Google send me back to the create-account page?
This almost always means the browser is blocking the cookies or scripts Google sign-in needs to hand you back to us. The usual cause is opening the site inside another app's built-in browser (a link tapped in Gmail, Facebook, or a text message) or a strict privacy or ad-blocking setting. Two fixes: first, open Chrome or Safari directly, type underpricedai.com in the address bar, and tap Continue with Google from there rather than following a link inside another app. Second, if it still loops, create the account with your email and a new password instead (not your Google password), and you'll get a confirmation email and you're in, and you can connect Google to the account later in Settings.
Security & Privacy
Is my data secure?
Yes. Images are stored securely in encrypted AWS S3 storage. Platform connections use OAuth - we never see or store your marketplace passwords. We support two-factor authentication (2FA) for additional account security.
How do I change or reset my password?
Use the password reset. On the sign-in page, tap "Forgot password?" (or go to underpricedai.com/forgot-password), enter the email on your account, and we email you a link titled "Reset Your Password". The link works for one hour; pick your new password there. To change a password while you're signed in, sign out and do the same; there is no separate change-password screen in Settings. If you signed up with Google or Apple, you can keep signing in that way, or use the same reset to add a password to your account. If no email arrives after a few minutes, check spam, then write to support@underpricedai.com from the address you signed up with.
Can I delete my data?
Yes. You can delete individual scans or disconnect a marketplace account at any time without touching the rest of your account.
How do I permanently delete my account and all my data?
This is separate from canceling. Canceling or pausing your plan just stops billing - your account, scans, and history stay. To permanently delete everything, go to Settings and use Delete Account, or visit underpricedai.com/delete-account and enter your email for a one-click deletion link (no login needed; the link expires in 30 minutes). Deletion is permanent and removes your account, scan history, saved items, and listings - it can't be undone.
Do you sell my data?
No. We never sell your personal information or scan data to third parties. Your scans and inventory data are yours. See our privacy policy for full details.
Reselling Tips
What are the best items to resell for profit?
Popular high-margin categories include vintage clothing (Levi's, Pendleton, Starter jackets), collectibles (Hot Wheels, Pyrex, depression glass), electronics, designer handbags, and athletic wear (Lululemon, Nike Dunks). Check out our blog for detailed guides on each category.
Where should I source items to resell?
Thrift stores, estate sales, garage sales, flea markets, and online auctions are the most popular sourcing spots. Our estate and yard sale finder (Estate & yard sales, under More on Pro Plus and above; on lower plans it is not listed, and underpricedai.com/pricing shows what each plan adds) opens the main estate sale, yard sale and auction sites already searched to your ZIP code.
Which marketplace should I sell on?
It depends on what you're selling. eBay is best for electronics, collectibles, and niche items. Poshmark excels for clothing and fashion. Mercari works well for general goods. Facebook Marketplace is ideal for large or local-pickup items. Many successful resellers cross-list on multiple platforms to maximize exposure.
