What to look for in a real grading AI

Five questions every collector should ask.

Is it trained on real PSA returns?

Demo tools generate plausible-looking grades but have no calibration against actual outcomes. Ask for the verified return count.

Does it publish accuracy data?

Real tools publish prediction-vs-actual data, including misses. Marketing-only tools claim "95% accuracy" with no source.

Does it grade by subgrade axis?

A real grader evaluates centering, corners, edges, and surface separately. A black-box single number is a red flag.

Does it refund low-confidence calls?

If a tool charges you for predictions it isn't sure about, it's monetizing guesses. SnapGrade refunds below 70% confidence.

Is it free to try?

Real tools let you test before you pay. SnapGrade gives 2 free credits with no card required.

Does it support your game?

Pokémon, Yu-Gi-Oh!, Magic, sports, One Piece. Check support before buying credits.
