Underpriced AI tells resellers what a secondhand item sells for. Give it a photo link or a description and it returns a calibrated estimate with a range, the recent real eBay sales behind it, three list prices with the two-week sell chance, the net after eBay fees, and a worth-it verdict when you say what you would pay. Ask for the comps themselves and it returns the most recent sales with the count, median and quartiles. Sign in and a photo price becomes a real scan saved to your account, and it can prepare an eBay listing draft that you review and publish. Prices are USD and reflect eBay US.
Example prompts
- “I can buy this for $12 at a yard sale. What would it sell for on eBay?”
- “What are vintage Pyrex Butterfly Gold bowls selling for right now?”
- “What should I list this at if I want it sold within two weeks?”
