Snap a board, paste a game or point your camera at a live one. Chess Revision reads the position, runs a cloud engine and shows you both the perfect move and the move a real player at your rating would actually find.
Free to scan and analyze. Premium unlocks the live feed, human moves and the deep engine.
A perfect engine is everywhere. A live camera that follows a game, and a move tuned to your own rating, are not.
Point your camera at a board on a screen or a real set and Chess Revision reads each move the instant it lands. No pausing, no manual entry. The evaluation, the best line and the move classification keep pace with the game, so you watch the turning points happen live.
Stockfish tells you the perfect move. It never tells you what a real person would do. Powered by Maia, Chess Revision shows the move a human rated 1100, 1500 or 2100 would actually pick in your position. Train against your own band instead of a 3500 engine and learn the moves you can realistically find over the board.
Run a full review and each move is rated from brilliant to blunder, with an accuracy score for both sides and a phase-by-phase breakdown. An evaluation graph traces the swings across the game, and one tap jumps you to the exact move that decided it.
Snap a photo or screenshot of any 2D board and the position is recognised in seconds. Paste a FEN or a full PGN. Or pull your real games straight from Lichess or Chess.com by URL, id or username, then step through them move by move.
