Know the grade before you pay for it.

No. It reports a ceiling: the best a company's grade could be, based on centering and edges measured automatically from your own two photos, plus corners and surface as your own guided call. Since a real grader's own inspection can land anywhere at or below that ceiling, the actual submitted grade can land below the number shown, but should not land above it.

Every grading company caps a card at its weakest attribute. The ceiling assumes your own corner and surface calls hold up, and that the automatic centering and edge reading holds too. A real submitted grade can land at or below it, but shouldn't land above it. That's also why a result here never reads as a bare PSA 9: it's always PSA 9 at best.

A phone photo taken in ordinary room lighting cannot reliably separate a scratch or a soft corner from glare on the shot, so a score from that kind of photo would be more guess than measurement. Instead, the tool asks two short questions: what the worst corner looks like, and what the worst surface flaw looks like, each with four plain, labeled examples to compare against. Your answer, not a guess from the photo, is what sets those two axes.

Centering lands within about one to two percentage points on a flat, evenly lit photo of a card with a printed border, and drifts further on heavy foil or under glare, or is reported as not measured on a full-art card with no printed border at all. Corners and surface reflect your own judgment against labeled examples, not a photo measurement, and a professional grader's closer inspection may disagree with either call.

No. Those are the three companies' names, used only to describe their own publicly published grading standards. This tool is not affiliated with, endorsed by, or partnered with any of them.

No. Every measurement (centering, edge condition) is computed from the two photos you take, entirely in your browser. No image is sent to a server at any point.

The tool locates the card's printed inner frame in your photo and measures the border width on each side, front and back, automatically. There is no manual line placement anywhere in this tool. When the front border can't be found (a full-art card, or a photo the detector can't read confidently), the result honestly says so and uses the back reading instead. The full breakdown of what each measurement can and can't tell you is shown next to the scores on the results page.

No. The tool works fully signed out, straight from your phone's browser, the same as the card scanner.

No. This tool only reports the physical-condition ceiling described above. It does not estimate a price, a return, or any recommendation about whether submitting a card is a good use of a grading company's fee.

Front centering has no printed frame to measure against, so it's reported as not measured rather than a made-up number, and back centering is used in its place when available. Edge findings and your own corner and surface answers still combine into a ceiling normally.
