Chess position scanner
Scan any chess position and get the best move
Point your phone at any chessboard — a real board at the table, a screenshot, or a diagram in a book — and ChessCopilot reads the position and shows the strongest move in seconds, powered by the Stockfish engine, offline.
What ChessCopilot can read
- ✓ Real, physical boards photographed at an angle — tilted, shadowed, mid-game.
- ✓ Screenshots from Lichess, Chess.com, streams, or puzzle apps.
- ✓ Printed diagrams from books, magazines, and worksheets.
What you get from every scan
- ✓ The position as a FEN string you can copy anywhere.
- ✓ The best move in standard notation, plus the evaluation in pawns.
- ✓ The top engine lines to study — and a "Play from here" board to explore.
How it works
Point your camera at the board. The vision AI recognizes every piece and rebuilds the position — you confirm it in one glance. Then the on-device Stockfish engine returns the best move, the evaluation, and the lines behind it. No account, and your positions stay on your phone.
Why on-device matters
Unlike scanners that need a server, ChessCopilot runs Stockfish directly on your phone. That means analysis works offline — perfect for a crowded tournament hall or a spotty connection — with no waiting and nothing uploaded.

How do I scan a chess position from a photo?
Open ChessCopilot, point your camera at the board (or pick a photo from your gallery), and the app rebuilds the exact position. You confirm it in one glance, then get the best move and evaluation instantly.
Can it scan a real, physical chessboard?

What does the scanner output?

Does the analysis work offline?
Yes. The Stockfish engine runs 100% on your phone. A connection is only used for the initial photo recognition step.
