SellRight alternative: know what it sold for before you pick a price
SellRight is an iPhone app for the things you have been meaning to sell: one photo becomes an editable draft with a suggested asking price, posted to Facebook Marketplace, Depop and eBay. Underpriced AI prices the photo from real eBay sold comps first, then drafts, crosslists and tracks the sale. First scan free.

What SellRight does well
The first listing. Take a photo, confirm the item, add the scuffs the camera missed, and the app writes a title and a description in a paragraph or its Quick Scan format, then suggests a price you can accept or change. Postage guidance names a service and an estimate for eBay and Depop, and an insights view shows item counts, marketplace status and estimated value. The first three listings are free, and it launches in Australia, the US, Canada and the UK.
Where Underpriced AI goes further
SellRight's own App Store listing says its prices are suggested asking prices, not verified valuations, and that similar-item matches show asking prices, not completed sales. An asking price is what another seller hoped for; a sold price is what a buyer paid, and that gap decides whether the $8 thrift find is a flip or a donation. Underpriced AI shows the real eBay sold comps behind every estimate, a calibrated range and the net after fees. It runs on iPhone, Android and the web, publishes to ten eBay markets and Bonanza, crosslists to Facebook, Depop, Poshmark, Mercari and more, tracks what each item netted, and publishes its measured pricing accuracy.

Common questions
How is Underpriced AI different from SellRight?
SellRight is for selling your own things from an iPhone: one photo becomes an editable draft with a suggested asking price, posted to Facebook Marketplace, Depop and eBay. Underpriced AI starts at the buy decision: the photo returns real eBay sold comps you can open and the net after fees, then the listing, crosslisting and profit tracking, on iPhone, Android and the web.
What does SellRight cost compared to Underpriced AI?
On its App Store listing on 2026-10-10: the first 3 listings are free, then a subscription is required, with two in-app purchases shown, Basic $19.99 and Seller Plus $119.99. The listing does not show their billing period; sellright.xyz says prices and included listings appear before you buy. Underpriced AI: free first scan, then Starter $5 a month for 15 scans, Pro $15 for 75, Pro Plus $29 for 200, or a $3 pack of 5 scans.
Does SellRight use sold prices?
Its App Store listing says no: prices are suggested asking prices, not verified valuations, and similar-item matches show asking prices, not completed sales. Its site FAQ calls the suggestion a starting point, not a crystal ball. Underpriced AI prices from completed eBay sales and shows you each one.
Which marketplaces does each one post to?
SellRight posts to Facebook Marketplace, Depop and eBay where available, which varies by region and needs your own account on each; Vinted is listed as coming soon. Underpriced AI publishes directly to ten eBay markets and Bonanza, and its extension fills Facebook, Depop, Poshmark, Mercari, Vinted, Whatnot, OfferUp and Etsy from one listing.
Does SellRight run on Android or the web?
The App Store listing says only for iPhone, iOS 18.4 or later, and nothing on sellright.xyz names an Android or web app. Underpriced AI runs on iPhone, Android, the web and a browser extension, so the same item can be priced in the aisle and listed from a desk.
