Gradeon

Gradeon is an AI-powered mobile app for pre-grading trading card game (TCG) cards. Built by collectors, it analyzes centering, edges, corners, and surface to deliver an instant grade estimate before sending cards to PSA, CGC, or BGS.

Gradeon helps Pokemon, Magic: The Gathering, Yu-Gi-Oh, and One Piece collectors decide which cards are worth professional grading — saving them time and money on submission fees for cards that wouldn't grade well.
