About FlipTip AI
FlipTip tells resellers what a second-hand item really sells for — from real completed sales, not asking prices — and whether it is worth buying, while the item is still in their hand.
Why it exists
At flea markets and garage sales the same two mistakes keep happening: people overpay for things they believe are rare, and walk past a valuable item because they don't recognise it. Checking sold prices on eBay with one hand while the seller waits is slow, and most people give up halfway.
FlipTip does that check properly: it identifies the item from what is printed on it, looks up what that exact item actually sold for, and turns it into a decision — your profit after the marketplace's fees, the most you should pay and a clear WORTH IT or SKIP.

How FlipTip works
- Identification. AI reads every label, logo and model number on the photo. The exact model is named only when it can point at the proof — a readable model number or a detail only that version has; otherwise you see what is certain and the likely versions.
- Prices. Recent completed sales of that exact item — eBay, and in the US also Mercari and Poshmark when eBay has few — with other versions, lots and parts left out. In countries without eBay data, the marketplaces people there use.
- The decision. Profit after the fees of the marketplace you sell on, the most to pay, what to offer the seller, how fast it sells and a verdict.
How we check ourselves
Every day FlipTip runs blind tests: it scans the photo of an item that has just sold on eBay, without seeing the sale, and compares its answer with what the item really sold for. The results — misses included — are public, with the method and every single test.
What FlipTip does not do: promise profits, authenticate luxury goods or replace a professional appraisal. It shows the evidence it used, so you can check it.
