MintQuest: AI Card Grader

Meet Professor Hoot, the monocled owl appraiser of the card world. MintQuest turns your phone into a pixel-art pre-grading lab so you can estimate your card's condition BEFORE paying for professional grading.

Photograph the front (and back for a fuller read) of any raw trading card and get an AI-estimated grade from 1 to 10 in seconds.

WHAT YOU GET

- Estimated overall grade (1-10)

- Four subgrades: Centering, Corners, Edges, Surface

- Defect list: whitening, dents, scratches, print lines and more

- Card identification (name, set and number when recognizable)

- "Worth grading?" verdict so you can submit smarter

WORKS WITH YOUR COLLECTION

Every scan is saved in your Binder, stored on your device only.

PRIVACY FIRST
