Photograph a stamp and get a centering score. Each score is measured from the real margins on your stamp, so you can see exactly why it landed where it did.
AI Stamp ID measures stamp centering from the margins themselves. Take a photo with your phone, and the app measures the left, right, top, and bottom margins and turns them into a centering score.
The measurement is deterministic. The same margins always produce the same score, so the result doesn't depend on who is looking or what kind of day they're having.
AI Stamp ID also compares single stamps and blocks of four against a reference library and suggests likely identifications, which you can confirm or dismiss.
The digital perforation gauge is built in, so the paper one can stay in the drawer.
Your collection lives in the app, with filtering and search to find any stamp in it.
Every stamp you analyze can have its own public page, so sharing a result with a dealer, a club, or a friend takes a single link.
AI Stamp ID is free to download. The Free Plan includes centering scores, the digital perforation gauge, single and block of four identification, and collection filtering and search, with 5 stamps a month and room for 5,000 stamps in your collection.
Stamp Identification Plan raises your limit to 250 stamps a month.
Stamp Grading Plan raises it to 1,000 stamps a month and adds downloadable sales trading cards and room for 20,000 stamps in your collection. It also includes 20 deep searches a month in the AI Stamp ID web app, on your computer or phone, when you sign in with the same account.
Both paid plans are available as monthly or annual subscriptions, and the annual option costs less than twelve months of the monthly one.
Payment is charged to your Apple Account when you confirm your purchase. Your subscription renews automatically unless you cancel at least 24 hours before the end of the current period. You can manage or cancel it at any time in your Apple Account settings.

The most noticeable change in this release is an improved identification experience, with stronger matching and clearer results to help collectors identify stamps from around the world more quickly.
We’ve also improved the grading and measurement tools, making it easier to evaluate centering, margins, perforations, stamp size, and other details directly from the stamp image.
The editing and results workflow is better too, giving collectors more control to review or correct an identification, refine measurements, and save a more complete record of each stamp.
We also fixed several issues that collectors reported, some of them more than once. Thank you for sending them in.
