What I've built

AI card grading · iOS, Android, Web

ZeroPop

Photograph the front and back of a trading or sports card and ZeroPop identifies it, grades corners, edges, surface and centering, and prices it from real market sales. Two AI models handle identification and grading, while measurement and fixed rules keep every grade consistent.
