Latest version
Version 0.4.1
Released Sep 11, 2026 - 4.44 MBWorks with firefox 140.0 and later, android 142.0 and later0.4.1
New: whole games. On a page that shows a game as a move list (chessgames.com, lichess, chess.com articles, blogs), fenshot finds it, checks every move is legal, and shows it on a small board you can step through with the arrows or the keyboard. One click opens the full game on Coachess or Lichess, or copies the PGN. Several games on one page? Page through them. Games with a custom starting position (studies, puzzles) are supported; Chess960 and other variants are recognised but not imported.
Changed: Coachess is now the primary analysis button, Lichess second. Links to Coachess carry a static utm_source=fenshot tag (no identifier, no data).
Permissions: adds "scripting", used together with activeTab on the click only, to read the page's visible text for the move list. No host permissions, nothing persistent, nothing leaves the device.
Board reading (screenshot → position) is unchanged.Source code released under MIT License
