About
Slabbr is the fastest way to know what a Pokemon card is worth while you're watching a Whatnot live auction. Press S while any card is on screen and Slabbr instantly identifies it and shows real market prices in a clean overlay — so you can bid with confidence and never overpay again. WHAT YOU GET - Instant card ID + live market pricing the moment a card hits the screen - Works on vintage holos, modern sets, and Japanese cards - "WON BID" tracking — log what you paid vs. market and watch your savings add up - A built-in collection to track the cards you win - A clean, unobtrusive overlay that stays out of your way HOW IT WORKS 1. Install Slabbr and pin it 2. Open any Pokemon stream on Whatnot 3. Press S when a card is on screen 4. See the card name + current market value instantly BUILT FOR WHATNOT BUYERS Whether you're hunting deals in breaks, sniping singles, or building a collection, Slabbr gives you the pricing edge that live auctions demand — no more frantic eBay-tab searches while the timer runs down. PLANS - Free — 8 scans/day (15/day for your first 30 days), 5-card collection - Basic ($9.99/mo) — 75 scans/day, unlimited collection - Pro ($24.99/mo) — 300 scans/day, unlimited collection FAIR SCANS If Slabbr ever misidentifies a card, just tap "report wrong" and we refund that scan — you're never charged for our mistakes. PRIVACY Slabbr only runs on whatnot.com. When you scan, the current video frame is sent securely to our service to identify the card — nothing else is collected or sold.
