GrailSweep

GrailSweep is the only multi-TCG AI card scanner with built-in fake detection — spot counterfeits, grade condition and check live market prices all from a single photo.

Supports Pokémon (English & Japanese), Magic: The Gathering, Yu-Gi-Oh! and One Piece Card Game across 167,000+ cards.

🛡️ FAKE CARD DETECTION

GrailSweep runs an AI authenticity check on every single scan before identification. Suspected fakes are flagged automatically — a feature no other TCG scanner app offers.

⭐ AI CONDITION GRADING

Two grading modes, one app.

- Auto Grade — instant condition estimate from every scan, no extra steps

- Deep Grade — full AI analysis with per-attribute scores for centring, corners, edges and surface. Get the insights you need before sending to PSA, ACE, BGS or CGC

📸 AI CARD SCANNER
