How we compared
We looked for apps and sites that give an AI grade estimate for trading cards, then checked each one's pricing, platforms, subgrades, supported cards and value features on official pages. We did not test accuracy head to head, and no app's accuracy claims (including Binder AI's own 87% figure, which is based on Binder AI's internal comparison of app estimates with returned professional grades) should be taken as a guarantee. Prices change often, so confirm on each official page before you buy.

The apps in more detail
Binder AI
Binder AI is an AI pre-grading app for iOS, Android and the web. You photograph the front and back of a card and get an overall grade estimate on the PSA, BGS or TAG scale you choose, with centering, corners, edges and surface subgrades and written condition notes. It also has a manual centering tool, identifies the card, shows eBay sold prices, price history and a graded value table, and sorts cards into binders by game or sport with sharing and wishlists. It supports Pokémon, Magic: The Gathering, Yu-Gi-Oh!, One Piece, Digimon, Lorcana, baseball, basketball, football, hockey, soccer, WWE and non-sport cards. The app is free to download, and grading is included in a subscription: $1.99/week, $3.99/month or $24.99/year on the website ($4.99/month or $29.99/year in the App Store).
Best for: collectors who want grading, pricing and collection tracking in one app across Pokémon, other TCGs and sports. Not for: anyone who needs an official grade; Binder AI's results are estimates. Read how AI card grading works.

How to choose
- You mainly want to know what to submit: pick an app with subgrades and the grading scale you plan to use, then check the money with our grading ROI calculator.
- You also want pricing and a collection in one place: look for sold-price data and binders alongside grading.
- You grade occasionally: credit-based tools can be cheaper. You grade often: a flat subscription can be simpler.
- Whatever you choose: good photos matter more than any app. Follow our scanning tips.
