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. Full policy: https://slabbr.pro/privacy
