Underpriced AI

The eBay listing tool that starts with one photo

The sales behind a price like this

In the 90 days to September 28, our archive captured 332 eBay sales matching “lady head vase”. The middle half went for $29.99 to $74.99.

The scan priced ours at $34.30, low in that spread; it sold for $45. Every scan lists the sold listings behind its price, each one a link to eBay, like these three from the archive:

The vase is a real find by a reseller in our family. Sales from our archive of eBay sold listings, read September 28, 2026.

The figures

On the 195 sales in the last 90 days where the seller set their own price, the typical gap between our estimate and the sale was 38%, and 41.5% sold inside our range. That is why every result shows a range and the sales, not one confident number.

Photo to live listing

Four steps, one of them yours

The scan does the research and the writing. You check it and choose how it sells.

  1. 1

    Photograph it

    One photo, or up to 12 angles of the same item for one scan. It is identified and priced from real eBay sold listings.

  2. 2

    Review the listing

    Title, description, category and the item specifics eBay requires, filled from the scan. Edit anything.

  3. 3

    Pick how it sells

    Fixed price or auction, reserve and Buy It Now, Best Offer rules, and a start time up to 21 days out.

  4. 4

    Publish from your account

    One tap, to any of ten eBay countries. It joins your Promoted Listings campaign at your own rate if you turn that on.

After it lists

Run the listing without Seller Hub

Change the price
Update a live price, or tap a 5, 10 or 15 percent markdown, without opening Seller Hub.
Best Offer on autopilot
Offers at or above your price sell; offers below your floor are declined for you.
End and relist
End a listing in one click. An ended one shows a relist card, at a new price if you like.
The sale comes back
When a listing you published from the app sells, the sale price, fees and shipping sync into your profit, no typing.
Already listed?
Import your active eBay listings so the whole store is in one inventory.
Sold somewhere else?
Turn it on in Settings and marking an item sold elsewhere ends its eBay listing too, so you do not sell it twice.

Questions

How is this different from eBay's own listing tool?
Underpriced AI starts before eBay does: it identifies the item from a photo and shows you the sold listings behind its price, each one a link, before you open a listing. After it lists, it tracks the item, syncs the sale and its fees, and helps you list the same item on other marketplaces.
Does it fill in eBay's required item specifics?
Yes. When you pick a category and condition, the form loads the item specifics and condition details eBay requires for that category and fills them from your scan where it can. You fill whatever is still blank and publish.
Can I list as an auction or schedule the listing?
Yes. Choose fixed price or auction. An auction takes a start price, a duration of 1, 3, 5, 7 or 10 days, and an optional reserve and Buy It Now. Any listing can go live now or at a time you pick, up to 21 days out.
Which eBay countries can I publish to?
The US, UK, Canada, Australia, Germany, France, Italy, Spain, the Netherlands and Belgium. Prices come from the sold listings of the eBay site that matches the country on your account, in its currency.
Do you see my eBay password?
No. You connect your account through eBay's own sign in page and eBay gives us permission to list for you. You can disconnect it in Settings at any time.
Is it free?
Your first scan is free with no card, and it shows the price and the sold listings behind it. Publishing to eBay needs a plan (from $5 a month) or unused scan pack credits (a 5 scan pack is $3).

Your first scan is free with no card. Then pay as you go at $0.25 a scan, buy a 5 scan pack for $3, or pick a plan from $5 a month for 30 scans. Compare plans.
