How the AI chess coach teaches
You play, the coach reacts. Each move is graded from Best to Blunder by Stockfish, with the evaluation and win chance before and after it. The AI then explains the position in the voice of a coach sitting next to you. It only explains what the engine found: every move, line, square and number on screen comes from Stockfish and the rules of chess, never from the AI.
Choose how much help you get
- Full lesson
- A full lesson after every move you play.
- Mistakes only
- A quick grade on good moves. The full lesson when you slip.
- Find it yourself
- After a mistake the answer stays hidden. Take the move back and find a better one.
- Hints before I move
- Ask for a nudge before you move. The coach never gives the move away.
Add a focus (tactics, strategy, calculation, openings or endgames) and pick Beginner, Intermediate or Advanced to set how technical the explanations are. The coach writes in your language.
What a lesson covers
- Why it's wrong
- What your move allowed, with your opponent's strongest reply and the refutation you can step through on the board.
- What was better
- The engine's best move, its evaluation and win chance, and the line that follows it.
- What it weakened
- Loose pieces, weak squares, an exposed king or a broken pawn structure, each one highlighted on the board.
- The calculation
- The candidate moves side by side with their evaluations and win chances, so you can see how far apart they are.
- Remember
- The one principle to take into your next game.
