fenshot: chess board to FEN, one click 作者： Coachess

See a chess position anywhere, on lichess, chess.com, a YouTube video, a book PDF, a blog post, and want to analyze it? Click the fenshot icon.

The extension screenshots the visible tab, reads the board with a neural network that runs entirely inside your browser, and shows you the position. From there:

• Analyze on Coachess, one click to coached analysis
• Open on Lichess
• Copy the FEN to use anywhere

Whole games too. On a page that shows a game as a move list, such as chessgames.com, lichess, a chess.com article or a blog, fenshot finds it, checks that every move is legal, and shows it on a small board you can step through. One click opens the full game on Coachess or Lichess, or copies the PGN. Several games on one page? Page through them.

Privacy, for real:

• The screenshot and the page text are read only when you click the icon (activeTab permission), and only from that tab
• Recognition runs 100% on your device, nothing leaves your browser
• No account, no analytics, no tracking, no network requests
• Fully open source (MIT): github.com/scoriiu/fenshot

Works with lichess and chess.com themes, book diagrams, and most piece sets. When a position is hard to read, fenshot says so instead of pretending, and routes you to an editor to fix the squares.

Built from the position-import engine of coachess.app.
