The pre-submission checklist every collector should run.

Cherry-pick the winners

Run your batch through SnapGrade and only ship the cards predicted 9.0+. Skip the borderline 7s and 8s.

Find the surprise hits

Sometimes a card you'd almost throw back grades as a 9. Pre-grading catches both directions.

Plan the right service tier

A predicted 10 belongs on Express. A predicted 9 fits Regular. Match the submission to the prediction and stop overpaying.

Keep your submission list organized

Your graded cards live in one dashboard, sorted by predicted grade — an easy at-a-glance view of which cards are worth submitting to PSA.

What does "checking your PSA grade before submission" mean?

Checking your PSA grade before submission means using an AI pre-grading tool to predict the most likely PSA outcome for a card before paying PSA's $25–$75 fee. SnapGradeAI's internal calibration figure — 87% of predictions within ±0.5 of the actual PSA grade, across 412 comparisons — comes from checking predictions against real PSA return grades we've logged directly.

How we calibrate accuracy

The 87%/412 figure is our internal calibration number today, not yet a live, per-card public log — we're building toward that. Every prediction also carries its own confidence level, and low-confidence predictions (below 70%) refund automatically rather than charging you for a guess we're not confident in.

We're building a public, per-card verified-returns log where any collector can submit their own real PSA result — cert number, publicly checkable on PSA's own site — and have it factored into the published accuracy figure. Today's number reflects our own internal calibration testing, not yet a crowdsourced dataset.

Accuracy snapshot

As of May 2026:

Where we're weakest

Vintage cards (pre-2003) are our hardest cohort — unusual aging signatures are under-represented in our training data relative to modern cards, so treat a vintage prediction as a rougher estimate than a modern one. We're actively working to close that gap.

Why this page exists

Most AI grading tools claim "95% accuracy" with nothing public backing the number. We'd rather publish a real, current figure — and be upfront about what it is and isn't yet — than a bigger-sounding number with no way to check it. See also: AI Pokémon card grading vs PSA — how close is the match?.

Common questions

Everything you actually want to know.

How does checking the grade beforehand save money?
PSA's economy service is ~$25 per card and Express runs $75+. If pre-grading flags 5 cards in your 20-card submission as likely 7s, you've avoided $125–$375 in wasted fees.
Will my SnapGrade match what PSA returns?
87% of the time within ±0.5, based on our internal calibration testing against 412 real PSA-return comparisons. We don't hide the miss rate.
What about borderline cards?
For low-confidence predictions (below 70%), your credit refunds automatically. We'd rather give you no answer than a misleading one.
How often is the accuracy figure updated?
As we log more real PSA-return comparisons. We're building a public, per-card version of this where collectors can submit their own results directly — until that ships, this is our internal calibration number.
Can I see the individual verified-returns data?
Not yet as a public per-card log — we publish the aggregate figures on this page. A full public log, with the ability to submit your own real PSA result, is something we're actively building.
How accurate is SnapGrade specifically on vintage Pokémon cards?
Vintage cards (pre-2003) are our hardest cohort — unusual aging signatures are under-represented in our training data relative to modern cards. We're actively working to close that gap.
