Ask Claude what something is worth and get the answer from real eBay sold listings, not a guess. Underpriced AI is built for thrift store, estate sale, garage sale and online resellers who want a number before they buy or list. Say what you have, as you would type it into eBay: brand, what it is, size or pattern, any marks. Or paste a public photo link. You get a calibrated estimate with a range, the recent sales behind it, three list prices (fast, market, patient) with the two week sell chance for each, and what you keep after eBay fees. Tell it what you would pay and you get a buy or pass verdict. Things people ask it: "What does a Pyrex Butterfly Gold mixing bowl sell for?" "Is this Coach bag worth $25 at the thrift store?" "Show me recent sold prices for a Leica M4 body." "I can get this KitchenAid mixer for $40. What would I clear on eBay?" "How much do vintage Levi's 501s go for?" Ask for the comps and you get the most recent sold listings with the count, median and quartiles, so you can see the spread, not just an average. Signed in to your Underpriced AI account, a photo price is a real scan saved to your history, priced in your own eBay marketplace and currency, and Claude can prepare an eBay listing draft from it that you review and publish yourself at underpricedai.com. Nothing is listed, bought or charged through the connector. Works without an account for a few questions a day. Prices are USD and reflect eBay US unless you are signed in. Cross list to Poshmark, Mercari, Facebook Marketplace and more from the app once you have the number.
