Chess Revision vs ChessCopilot

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.

Scan games, analyze moves, improve faster. ChessCopilot turns any chess board — a real board, a screenshot, or your handwritten score sheet — into instant Stockfish analysis. Start with a 3-day free trial — full engine analysis on your own boards and games, no commitment. Cancel anytime before it ends. HOW IT WORKS • Scan a position — a photo of a real board or a screenshot from any app or video. ChessCopilot recognizes the pieces and runs Stockfish to find the best move and the top lines. • Scan a score sheet — photograph a handwritten or printed game; ChessCopilot reads the moves, checks them for legality, and lets you review the whole game move by move. • Play from here — continue any scanned position against the engine's suggestions, no re-scanning needed. WHAT YOU GET • Real engine analysis powered by Stockfish — best move, evaluation bar, and the top variations. • Whole-game review — accuracy, blunders, mistakes, and the key moments. • Save your games and export them as PGN. • Open any position or game in your favorite analysis site to dig deeper. • No ads, ever. No account or sign-in — your games stay on your device. WHO IT'S FOR Club and improving players who want fast, honest feedback: settle a "what's the best move here?", review the game you just played from your score sheet, or study a position you saw online. SUBSCRIPTION Start with a 3-day free trial, then keep ChessCopilot with an auto-renewing subscription. Each plan has a clearly stated daily scan allowance (never "unlimited" — every scan is a real AI request, so the limit is honest and shown up front): • Casual — 20 scans/day • Pro — 50 scans/day • Pro Yearly — 50 scans/day, best value A note on accuracy: recognition is AI-powered and isn't perfect — glance at the recognized board before trusting it, and fix any misread piece with a tap. Payment is charged to your Apple ID at the end of the 3-day free trial. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel anytime in your App Store settings.
