ChessBuddy AI

Your AI chess coach, right next to the board on lichess.org.

ChessBuddy puts a friendly AI chess coach right next to the board on lichess.org. Ask anything about the position in front of you and get a clear answer in plain language: no engine numbers to decode. WHAT BUDDY DOES • Puzzles: ask for a hint that points you in the right direction without giving the answer away. Buddy cheers when you solve it and helps you understand what you missed. • Game review: open a finished game or the analysis board and ask why a move was a mistake, what the plan was, or where the game turned. • Openings: learn the ideas, typical plans and traps behind the opening you are looking at. • Practice against the computer: get tips while you play the lichess AI. • Watching games: let Buddy explain what is going on in a top game on lichess TV. • Voice: talk to your coach instead of typing. THREE COACHING STYLES Coach (explains and asks you questions), Analyst (concrete and precise) or Assistant (short answers). Switch any time. FAIR PLAY BUILT IN Outside help in games against other people breaks lichess's rules, so the chat locks during your own rated games against humans and unlocks when the game ends. In unrated games against humans Buddy gets no engine lines and suggests no moves. Puzzles, bot games, analysis, openings and TV are fully open. FREE TO START Sign in with your ChessBuddy account. The free plan includes 10 coach messages and 5 voice minutes a month; paid plans at chessbuddyai.com include more. The same account works in the ChessBuddy web app. FITS INTO LICHESS On wide screens the chat sits in lichess's side column, level with the board. On smaller screens Buddy waits in a corner as a floating chat you can move and resize. Follows lichess's light and dark theme.
