Chess Revision: Live Scan

The move that lost you the game is hiding in plain sight. Chess Revision finds it.

Point your camera at any 2D board, on a screen or in a screenshot, and in a second it becomes a fully playable, fully analyzed game. No manual setup, no typing in pieces.

WATCH ANY GAME LIVE
Aim your camera at a game in progress on a screen and Chess Revision reads every move as it is played and analyzes it in real time. It is an engine looking over your shoulder.

EVERY MOVE, SCORED
Tap any piece and each square it can reach is scored right on the board, best move to blunder. You see what a move costs before you play it, not after. Five pieces a day are free.

THE HUMAN MOVE, NOT JUST THE ENGINE MOVE
Engines only tell you the perfect move. They never tell you what a real player would actually do. Powered by Maia, Chess Revision shows the move a human at your exact rating would play, so you train against reality instead of a 3500-rated machine.

PLAY IT OUT INSTEAD OF WONDERING
Think you were winning? Take the position over and play it to the end against Maia at your own rating, from a game you scanned, a game you imported or a board you set up by hand. Take a move back, ask to see the best move, or change the rating you are facing without leaving the game. One game a day is free.

SEE WHAT WENT WRONG
Run a full game review and every move is graded, from brilliant to blunder, with an accuracy score for both sides. Jump straight to the moment the game turned.
