Three grading companies. One honest prediction.
Professional grading costs $79.99 a card and takes about ten weeks. TAS reads the same four things a grader looks at — from a photo, in about ten seconds, before you spend anything.
Photograph both sides
Photograph the front and the back, or drop in images. Your browser finds the card and trims each photo to it, and warns you when the card is too small in the frame to judge. Nothing is uploaded until you press Get my grade.
A vision model looks it over
The photos go to an AI vision model — GLM through OpenRouter, with Google Gemini as a backup — which is told to check the borders for centering and the surface, corners and edges on both sides, and to name every flaw it counts.
A vision model grades all three companies
TAS predicts an honest 1–10 for PSA, CGC and BGS — weighing each company's own quirks. PSA tolerates slightly soft corners; BGS wants near-perfect subgrades. Three verdicts from one card's photos, each with the reasoning written out.
Decide whether it clears the fee
For Pokémon cards you get the current raw market price from TCGplayer, dated, beside an estimate of the value at the predicted grade — enough to judge whether a $79.99 submission makes sense. The graded value is an AI estimate, not sold-listing data, so check recent comps before acting on it.
Under the hood
Before you trust it
Don't take our word for it.
TAS is new, and you have no reason to trust it yet. So here is exactly what happens to your photo, the standard your card is held to, what TAS can't see — and how to test it on a card whose grade you already know.
Where your photo goes
Four stops, in order. Nothing leaves your device until you press “Get my grade”.

The card is found and each photo trimmed to it on your device. Nothing has gone anywhere yet.
- 02GLM via OpenRouter (Gemini as backup), when you ask for a grade
The front and back photos, and the card name if you typed one, are sent to our AI provider to produce the prediction, under its API terms.
- 03Our server
The scan isn't stored with your photo. If you save the card to your collection, a preview copy is kept with it so you can see it later — delete the card and it goes.

The yardstick, in public
Centering is the easiest flaw to check yourself. Measure the left and right borders with a ruler, work out the ratio, and hold it against PSA's published limits for the front of a card. If your result blames centering, the two should agree.
A ratio is the wider border's share first. Off-centre on either axis counts; the worse axis sets the cap. Corners, edges and surface can only pull the grade lower.
| PSA grade | Worst front centering allowed |
|---|---|
| 10 | 55/45 |
| 9 | 60/40 |
| 8 | 65/35 |
| 7 | 70/30 |
| 6 | 80/20 |
| 5 | 85/15 |
| 4 | 85/15 |
| 3 | 90/10 |
| 2 or lower | worse than 90/10 |
What TAS can't do
A photo is not the card. These are the gaps, stated up front rather than in the small print.
TAS asks for the front and the back, because back corners and edges are where wear often shows first. But a photo can hide a soft corner or a dent a grader would feel — look the card over in hand before you submit.
TAS predicts condition, not whether a card is genuine. A good-looking fake gets a good-looking grade.
Glare, sleeves and toploaders add reflections that can read as scratches; blur and angle hide real ones. A poor photo gives a poor prediction.
We haven't compared enough predictions against grades that came back from PSA, CGC and BGS to publish an honest number, so we don't publish one.
The raw price is real TCGplayer market data, dated. The value at the predicted grade is the model's estimate — check recent sold comps.
TAS isn't affiliated with PSA, CGC or BGS. Only a company that physically examines the card can grade it.
Test it before you rely on it
The free plan gives you 3 scans a day — enough to try all three of these without paying anything.
Photograph a slabbed card straight on, with no glare on the case, and compare the prediction to the label. That's the fastest way to learn how far to trust it.
Measure the borders with a ruler and hold the ratio against the table above. If your result says centering capped the grade, the ratio should back it up.
Each grade names the flaw that set it — a whitened corner, a scratch, a thin border. Find it on the card in your hand. If it isn't there, the grade is wrong.
Know what your card would grade before you pay anyone.
Scan a card now for a predicted PSA grade with the working shown — CGC and BGS side by side on any paid plan.
