AI Pre-Grade
Grading costs money and weeks of waiting. AI Pre-Grade tells you, before you pay, how a card is likely to score. Here is what it looks at and how far you should trust it.
Condition
The same four things a human grader weighs, scored from your photos. Swipe through them to see what each one covers.
How evenly the border runs on all four sides, front and back. This is the single most common reason a card misses a 10: further out than roughly 55 to 45 and the top grade is gone, however clean the rest is.
9.4out of 10
Sharpness and whitening, checked corner by corner at high magnification. One lifted fibre is enough to show up in the reading.
9.1out of 10
Nicks, chipping, and wear along all four edges, including the print line along the cut.
9.1out of 10
Scratches, print lines, dents, and how the holofoil catches the light. Glare in your photo is kept apart from real damage on the card.

Worked example
Real chase cards with example readings, so you can see how the estimate presents itself. Your own card gets its own numbers in the scanner.

How to read it
What the estimate can tell you, where it stops, and how to get the most out of it.
You photograph the front and back of a card. GrailPilot measures the same four things a grader looks at, and turns them into a grade estimate plus the odds of a PSA 10.
The result is a range with a confidence level. When the photos are too dark, too blurry, or cut off, you get told to shoot again instead of getting a number that means nothing.
An AI Pre-Grade is our estimate, never an official PSA grade. At PSA a person looks at your card, and they can reach a different call.
Treat the number as a filter, not a verdict. It is very good at telling you which cards clearly should not be submitted, and reasonably good at spotting the ones that deserve a closer look.
We will never tell you a card is a guaranteed 10, because nobody can.
Not yet. Slab reading is on the way.
Identification does. Grade estimates work the same way, since condition has no language.
Only to run the estimate and to show it back to you. You can delete them with your account at any time.
Scan a card and read the same four measurements on something you actually own. It costs nothing.
