What a comic grading app should do
A good comic grading app turns your phone into a pocket grader: snap a photo and get a reliable condition grade and a value estimate in seconds. ComicMintAI does exactly that — it grades on the 0.5–10.0 CGC-standard scale and pairs each grade with a market value from recent sales, all in your mobile browser with nothing to install.
How to grade a comic with the app
- Open ComicMintAI in your phone browser — no App Store download.
- Snap the front and back of the comic in even light.
- Get an instant grade with a sub-grade breakdown (centering, corners, edges, surface).
- See the value estimate for that grade, and save it to your synced collection.

App grading vs. mailing books to CGC
A phone-based grading app gives you an answer in seconds and costs nothing to start; mailing books to CGC costs $30+ each and takes weeks. The app is ideal for cataloguing, buying decisions, and pre-screening; CGC still makes sense for certifying high-value keys before resale. See the full comparison in our CGC alternative guide and the cost breakdown.
Tips for the best results from your phone
- Shoot straight-on, filling the frame, with even light and no glare.
- Capture both covers — back-cover defects affect the grade too.
- Use a plain, dark background so edges and corners read clearly.
