Chess Coach

Chess Coach turns Claude into a patient chess coach for your own games. Tell Claude your Chess.com or Lichess username and pick a game: Chess Coach analyzes it move by move with the Stockfish engine and shows it on an interactive board right in the chat.

What you get:

• The two or three moments that teach you the most, numbered on the board (①②③) and explained below it in plain language, without notation or numbers unless you ask for them.
• Arrows for the move you played and the better one, an evaluation graph, accuracy for both players and every move classified.
• Practice mode: replay the positions where you went wrong and find the better move yourself.
• Follow-up questions: ask "why?" from the board, try your own ideas and compare several positions in a carousel.
• Search your whole history by month, opponent, result, color, time control or opening, or paste a game link or PGN.
• Opening reports for you or your next opponent, a five-area player profile (blunders, tactics, clock, converting won positions, openings) and drills built from your own mistakes.

Every evaluation comes from Stockfish and every move description is computed from the rules of chess, so Claude explains real analysis instead of guessing. Chess Coach only reads public, finished games: it never asks for your chess password and never helps with games in progress.

Plans: Free includes one in-depth review a day. Plus ($3.99/month) adds 10 reviews a day, the player profile and the drills. Pro ($7.99/month) is unlimited with fair use. Sign in with email or Google.
