The best AI card grading apps

An AI pre-grade will not replace PSA, but it tells you which cards are worth the fee and which to sell raw. These apps estimate the grade from photos; here is what each one judges and costs. Facts checked October 14, 2026.

Questions

Are AI card grades accurate?

They are estimates from photos: glare, sleeves and photo quality hide defects that a grader sees in hand. Use them to sort cards, not as a guarantee.

Which grading companies do these apps estimate?

Midpoint estimates PSA, BGS, CGC and TAG. Check each app’s listing for the others.

Use our card centering tool to pre-grade your card in 30 seconds.
