Built for collectors of English and Japanese cards — singles, sealed product, and graded slabs. AI Card Scanner Point your camera at any card. CollectorBased identifies the card, set, and number instantly, confirms the condition, and adds it to your inventory with live pricing. No typing, no scrolling, no guessing. Live Market Prices Real prices on every card, refreshed daily. Condition-specific values for NM, LP, MP, HP, and DMG, plus graded slab data for PSA, CGC, BGS, and TAG. See what your collection is actually worth, not what someone wishes it was worth. Inventory Tracking Singles, sealed product, graded slabs, and custom lots in one place. Add by scan, search, or CSV import. Every card carries its purchase price, condition, and current market value, automatically. Show Mode Sell at card shows from your phone. Live pricing on every scan, quick-sell without pre-loading inventory, generate a QR code for buyers, and session data persists offline. Built for the dealer behind the table.

Export everything to CSV or PDF when April comes.
