WELCOME BACK TO THE HOBBY. You shouldn't need a padded envelope, a three-month wait, and a prayer to find out what your card is. AOG grades your card in minutes — and shows its work. THE PRAXIS PROTOCOL Every grade runs the same fixed forensic pipeline. Centering is measured, not eyeballed. Corners, edges, and surface are analyzed independently, and a committee of AI models cross-checks the result before your grade is issued. You get a 0–100 composite, four subgrades, and grading notes in plain language — because a grade with no explanation is just a rumor with a number on it. YOUR VAULT Every card you grade or add lives in your vault: filter by sport, search your collection, track values, and mark cards for sale or personal collection. Your cards, organized like they matter — because they do. SLABS WORTH FLEXING Your graded card becomes a digital slab with a scannable QR certificate anyone can verify. Choose from hundreds of slab designs — earn them, open them in packs, or pick them up in the store. Then share the flex. WHAT'S INSIDE - Forensic AI grading with centering, corners, edges, and surface subgrades - Plain-language grading notes on every card - Digital slabs with public QR-verified certificates - A collection vault with search, filters, and value tracking - Hundreds of collectible slab designs and pack openings - Card identification that fills in the details for you THE STRAIGHT TALK AOG grades are AI-powered digital assessments of your photos — built to be consistent, transparent, and explained. AOG is not affiliated with any physical grading company, and a digital grade is not a physical certification. We just think you deserve to know what you're holding without mailing it away. TOKENS & SUBSCRIPTIONS Grading runs on Gold Grade Tokens and slab designs run on Mint Tokens, available through in-app purchases. Optional subscriptions (Collector, Pro, Elite) deliver tokens monthly. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the period; manage or cancel anytime in your App Store account settings. Slab. Flex. Repeat.
