How Scanner works

1Capture

Take a photo or choose a JPEG, PNG, or WebP image.

2Review

CAISSA finds the board and asks you to check every recognized piece.

3Continue

Edit if needed, then analyze the confirmed position with Stockfish 18.

Less manual setup

Capture positions from popular chess sites, apps, screenshots, broadcasts, and photos of screens.

Always editable

Recognition can make mistakes. Review/Edit remains the required safety step before a position is accepted.

Privacy by choice

Scanning does not silently share your image. Optional feedback separates correction consent from image consent.

Best inputs

Digital 2D boards, screenshots, website or app boards, broadcast boards, photos of screens, and clear printed diagrams.

Current limits

Physical 3D boards, heavy occlusion, severe perspective, and HEIC/HEIF files are not supported in this beta.

Help improve Scanner

Optional corrections enter an unverified private vault. They never train the model automatically and require owner certification.
