Underpriced AI
Photograph it. See what it actually sold for
Photograph the item. Underpriced AI shows what it sold for and the sold listings behind the number, then lists it on eBay from the same screen.
Graded weekly against 379 real sales, published win or lose. See the grade.
ChatGPT answers. We help you sell.
ChatGPT and Gemini guess a price, then the chat ends. We show the sold listings behind it, post your listing to eBay and eight more marketplaces, and track it until it sells.
Love ChatGPT or Claude? Keep them. Add Underpriced AI to your chat and ask for real sold prices without leaving it.
The price
From real sales, checked every week.
Your number never rests on one feed. A specialist sold-price API goes first, a second independent vendor steps in when it comes up short, and our own scraping and archive of over a million sales cover the rest.
Read moreEvery week we check our estimates against what items actually sold for and publish the result, wins and misses, category by category. You can judge the number instead of taking it on faith.
Read moreThe listing
Written once, posted everywhere.
One click fills in a listing on Facebook, Poshmark, Mercari, Depop, Vinted, Whatnot, OfferUp and Etsy from an item you already priced. The extension is free for Chrome and Firefox.
Read moreWhen you publish to eBay, the listing joins your existing Promoted Listings campaign at the ad rate you already chose, instead of letting eBay apply its own suggested rate to it.
Read moreYour way
Where you work, and how you pay.
Add us to Claude, ChatGPT or your coding assistant and it can price an item, pull sold comps, say whether it is worth buying and draft an eBay listing, all without leaving the chat.
