Check your card before you pay to grade it.

Photograph a raw card, front and back. PROOF gives you an AI read of its condition and a vote from other collectors, and keeps a public record of the result.

Sports, Pokémon, One Piece, MTG, and more. Saga and Seeker are the reference devices, but any Android collector with a Solana wallet can join the alpha.

JOIN THE TESTER LIST

Help us decide what gets graded.

We approve testers through Discord. Wallet is optional, and Saga / Seeker holders are pre-approved automatically on first connect. Tell us how you handle raw cards so the alpha can tune toward real collector workflows.

PROOF complements market-data tools rather than replacing them: the app asks whether a card should move forward, not just what a comp says today.
