An AI pre-grading tool for trading-card collectors that maps defects, calculates centering, and estimates grading outcomes from guided photos.

Its reports pin defects to the confirmed card crop, keep confidence separate from the estimated grade, and let users dismiss false positives or move centering guides before recalculating.
