Game summary
Every move gets a clear verdict. When a move went wrong, an arrow shows the better one and a short note says why it mattered.
Human insight
The engine knows the best move, but people often don't find it. A model learned from real games shows which moves players of your rating usually choose.
Your patterns
After three analysed games the coach shows which kinds of mistakes cost you the most, like leaving pieces undefended or missing forks.
Training
Your mistakes become exercises. Find the move you missed, with hints when you need them: first the idea, then the piece, then the kind of move.
AI coach
Ask why a move was bad or what the plan should have been. The coach sees the whole game, and every move and number it mentions is checked with the engine before you see it.
Practice games
Play on from a position against an opponent that moves like a real player at the level you choose, not like a cold engine. You can even practise against one that plays in your own style.
Progress
Progress is measured on fresh positions you haven't seen before, so it shows real learning, not memory. Every estimate shows how certain it is.
This product never assists with games in progress on any chess site. Only finished games are analyzed.
Verdicts come from Stockfish, a leading open-source chess engine. The coach's answers are checked against it before you see them.
Download everything or delete your account at any time. Your games are never used to train models for anyone else.
Estimates show their uncertainty, and newer features are marked experimental until they are proven.
No card needed to sign up. Prices are shown in the app before you pay.
