Three verticals. One app.

Built for the way each grader actually measures.

Capture flow, sub-grade rubric, and accuracy model are dialed per vertical. No one-size-fits-all single-photo guess.

01
Comics

CGC-shape sub-scores.

Three guided photos — front, back, spine. We return cover wear, spine stress, corner blunting, and page quality on a 10.0 scale, calibrated to CGC and CBCS.

Centering is the kingmaker.

Two photos — front and back. BGS-shape sub-grades: centering, corners, edges, surface. Outcome-reportable against PSA, BGS, SGC, and BAS.

How it works

Shoot. Score. Decide.

01

Shoot.

Type-aware overlays guide each photo — three for comics and manga, two for cards. The frame brackets snap onto the cover; the app catches glare, misalignment, and blur before you tap.

Capture flow — aligning the back cover of a manga volume
02

Score.

A predicted grade with confidence and four sub-scores. About fifteen seconds. No human in the loop.

03

Decide.

A clear verdict — slab it, sell raw, or pass. Submit only the ones worth slabbing. Skip the rest. Report your real grade later to keep us calibrated.

Why this isn’t another AI scanner

Published accuracy. Per vertical.

Every prediction is checked against real CGC, CBCS, MGS, PSA, BGS, SGC, and BAS outcomes that users report back. We publish per-type calibration — mean absolute error, hit-rate within ±0.5, and a sub-grade breakdown — so you know exactly what you’re trusting.

Gradeyes predicts likely grades. Not affiliated with or endorsed by CGC, CBCS, MGS, PSA, BGS, SGC, or BAS.

FAQ

Questions, honestly answered.

Still curious? Email support@gradeyes.com and we’ll get back within a business day.

Does Gradeyes guarantee a grade?

No. We predict a likely grade with a confidence score. Final grades are issued by the third-party graders (CGC, CBCS, PSA, BGS, SGC, BAS). Use the prediction to decide whether submission is worth the fee.

Which graders do you support?

CGC, CBCS, and MGS for comics and manga. PSA, BGS, SGC, and BAS for trading cards. Outcome reports are accepted against any of them.

How many photos do I take?

Three for comics and manga (front, back, spine). Two for cards (front, back). The capture flow walks you through each one.

How accurate is it?

We publish per-type accuracy as Phase 1 outcomes accumulate. The calibration gates we ship under are mean absolute error ≤ 1.0 for comics and a ±0.5 hit-rate ≥ 65% for cards.

iOS, Android, or both?

iOS first, Android shortly after. Download the version that matches your phone — both are listed on the home page.

Are you affiliated with CGC, PSA, or BGS?

No. Gradeyes is an independent pre-screen. The graders’ rubrics inform our model, but we’re not a partner, reseller, or referral channel for any of them.
