Is there a free online card grader?
Yes. CardMintAI's online card grader is free to try with no credit card required. Two free grades, full PSA-standard analysis (centering, corners, edges, surface), same AI as paid users.
How accurate is online card grading?
CardMintAI achieves 95% alignment with PSA grades by analyzing the same four attributes professional graders evaluate. High-quality photos with even lighting yield the most accurate results. Best used as a pre-screening tool before PSA submission.
Does online card grading replace PSA?
No. PSA provides authenticated, encapsulated grades that carry market value for resale. Online AI grading is faster, cheaper, and ideal for deciding which cards are worth PSA fees — but a PSA slab is what buyers actually pay premium prices for.
Can I use an online card grader on my phone?
Yes. CardMintAI is a progressive web app — works on any phone (iPhone, Android), tablet, or desktop browser. Take a photo with your phone camera, upload, get your grade. No app store download.
What card types work with online grading?
All major card categories: Pokémon, Magic: The Gathering, Yu-Gi-Oh, baseball, basketball, football, hockey, soccer, and more. The AI evaluates universal physical attributes (centering, corners, edges, surface) regardless of card type.
Is online card grading legitimate?
Yes — within its scope. AI-powered grading is a real, accurate pre-grading tool used by 10,000+ collectors and dealers. It's not a substitute for PSA encapsulation, but it's a legitimate, validated tool for deciding which cards merit PSA fees.
