Get an instant, AI-powered grade prediction for your comics, manga, and trading cards — before you spend $50+ sending them to a professional grading service. Gradeyes uses computer vision to estimate what CGC, CBCS, PSA, BGS, SGC, BAS, or MGS would give your collectible. Snap a few photos and get a predicted grade with sub-score breakdowns in seconds. WHY USE GRADEYES • Decide whether to submit or sell raw — a 7.0 comic isn't worth a $50 grading fee • Negotiate confidently when buying or selling • See exactly what's holding your grade back — cover wear, spine stress, corner blunting, and more • Track your collection's grade distribution over time HOW IT WORKS 1. Pick what you're grading: comic, manga, or trading card 2. Take photos of the front, back, and spine (cards: front and back) 3.
