A Different Approach to Card Assessment
Most pre-grading services give you a number. We show you why — probability distributions, component scores, flaw evidence, and confidence bands so you actually understand what's driving the estimate.
Getting Started
Create a free account in seconds — no card on file required just to look around. Each new account starts with the option to try the service before purchasing credits.
When you're ready, head to the Pricing page to buy a credit pack. One submission uses one credit, and credits are valid for 6 months from purchase.
Submitting Your Cards
Go to Upload and drag-and-drop your photos. Each card needs a front and a back image.
Photo tips for the best results
- Bright, even lighting (no harsh shadows or glare)
- Card fills most of the frame — fully in-focus
- Plain background (a tabletop, mat, or neutral surface)
- Hold the camera parallel to the card so corners look square
Add the card identification details (set, year, player, etc.). Click Submit — one credit is deducted per submission and analysis usually completes within a couple of minutes.
Reading Your Results
Each result page shows a predicted PSA grade, a probability distribution across grades 1–10, and detailed sub-grades for centering, corners, edges, and surface.
The confidence band tells you how certain the model is. A tight band on a single grade is high confidence; a spread across two or three grades means the card sits near a boundary and could go either way.
Open the flaw heat-map to see exactly where the AI flagged issues — surface scratches, corner softness, or off-centering. Toggling these helps you understand why the predicted grade landed where it did.
Help Us Get Better — Report Real Outcomes
Once you get a card back from PSA, come to your submission and click Report Actual Grade. Enter the real grade you received — that single click feeds the validation loop and helps the model improve over time.
Reporting outcomes is optional, but it's the most valuable thing you can do for the community.
Frequently Asked Questions
Is this an official PSA grade?
No. AI Grading Lab provides AI-generated PSA-aligned grading estimates only. We are not affiliated with or endorsed by PSA. Always treat results as a guide, not a guarantee.
How accurate is the prediction?
The model performs strongest on common modern issues (centering, corner wear, surface scratches). It tends to under-call hard-to-see flaws like print lines or microscratches that PSA graders may catch in person. Use the confidence band as a sanity check.
Do credits expire?
Yes — 6 months from the date of purchase. Six months is plenty of time to work through a meaningful batch of cards, and that policy is exactly what lets us keep the per-card price as low as it is.
Can I refund unused credits?
Credits are non-refundable, but they don't lock you into a subscription either. You only ever pay for what you actually use.
