Scan a Chess Position — Screenshot to FEN Converter

Upload a screenshot from Chess.com, Lichess, a book diagram, or anywhere else you've spotted an interesting position. The scanner detects the board, every piece, and its orientation automatically, converting it straight into a FEN — no manual square-by-square setup required. Everything runs on-device in your browser; nothing is ever uploaded to a server.

How it Works

  1. Everything runs locally in your browser through a small on-device model — your screenshot is never uploaded anywhere.
  2. The board, every piece, and its orientation are read automatically — no manual steps.
  3. Fine-tune anything by dragging pieces, then continue to the analyzer to set whose turn it is.

Tips for Best Results

  • Screenshots and diagrams work best — chess.com, Lichess, books, and similar sources.
  • Photos of a physical board taken at an angle aren't supported yet.
  • A clear, uncropped, well-lit image reads most reliably.
