The Comic Grading App That Answers "Is It Worth It?"
ComicMintAI is a browser-based comic grading app — snap a photo on any iPhone or Android and get a CGC-style grade band, what the book is worth raw and slabbed, and whether the $27–45 submission pays for itself.

What the Comic Grading App Gives You
Enough of the grading rigour to make the submission call, in something that lives in your pocket.
CGC-Style Grade Band
Snap a photo and the app returns a band on the CGC 0.5-10.0 scale with a confidence level, plus the subgrades behind it.
No Download Needed
It runs in your mobile browser. Nothing to install from the App Store or Google Play — just open the link and grade.
Raw and Slabbed Value
Every grade comes with market value from real recent sales — ungraded and slabbed — so the gap the submission is chasing is visible.
Works on Any Phone
iPhone or Android, the app uses your standard camera — no special lens or scanner required.
Decide at Conventions
Pull up the app at a con, shop or estate sale and see whether the asking price leaves anything once condition is priced in.
Your Collection, Synced
Graded books save to the cloud and sync across devices, so your collection is always with you.
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 answers the question before any money moves; mailing books to CGC costs $27–45 each plus handling and shipping both ways, and answers it about 45 days after the money has already gone. Use the app to catalogue, to price books at shows, and to work out which copies justify a submission. CGC still makes sense for certifying high-value keys before resale — on the books that earn it. 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.

Grade your whole collection on the go
Because it runs in the browser and syncs to the cloud, the app is built for the real world: pull it up at a convention, comic shop, or estate sale and grade dealer books on the spot before you buy. Your graded collection travels with you across every device.
Built for the people who live in the long boxes.
Will this book pay for its own submission?
CGC is $27–45 a book plus handling and shipping both ways. Find out which of your comics clear that bar — and which ones never will — before the box goes out.
Price it, don't guess it.
A defensible comic grading report on every listing, and a straight answer on whether slabbing it first would net you more than selling it raw.
Raw or slabbed?
See both numbers side by side — what the book fetches raw today against what it fetches slabbed, minus the fee.
Route a whole collection.
Sort a long box by expected net return, then send only the books that clear their own break-even grade.
Skip the costly misfires.
Find out which books are NO-GO before the box goes out, not 45 days after it comes back.
Priced against one wasted submission.
Pay once, per decision. No subscription, and nothing to cancel — because deciding whether to slab a book is something you do a few times a year, not every month.

Comic Grading App FAQ
Do I need to download the comic grading app?
No. ComicMintAI runs entirely in your phone's browser — there is no App Store or Google Play download. Open the site, sign in, and start grading. This means it works on any device with a camera.
What does the app return for each book?
A CGC-style grade band with a confidence level, the subgrade breakdown behind it, an estimated value raw and slabbed, the full cost of a CGC submission, and the verdict — GO, NO-GO or PRESS FIRST — with the break-even grade beside it.
Can I work through a whole box?
Yes. Book after book, and the results save to your collection so you can sort the box by expected net return and submit only the copies that clear their own break-even grade.
How accurate is app-based grading?
A modern phone camera captures enough detail to place a book in a grade band, which is what the submission decision needs. It will not catch everything a grader holding the book would, so the report shows the band and its confidence rather than a single number.
Does the app work on iPhone and Android?
Yes. Because it is browser-based, the app works on any modern iPhone, Android phone, tablet, or computer.
