Chess Goat
About Chess Goat
Chess Goat is a website that analyzes a chess.com player’s public games with the Stockfish chess engine and shows what is really costing them rating points. It is for chess.com players who want to know why their rating is stuck and what to practice next. Chess Goat only uses public chess.com data, and it isn’t affiliated with chess.com.
Chess Goat (also written ChessGoat) lives at trychessgoat.com. It is a training site, not a ranking of the greatest players of all time: the goat is the mascot.
What is Chess Goat?
Chess Goat has five parts, all built on the same public chess.com games:
- Goat Card: free. A player’s habits from their clocks and results, in a few seconds.
- Free game review: free and unlimited. Stockfish review of any of your chess.com games, or any game you paste as a PGN, at trychessgoat.com/game-review/.
- Goat Report: $5 at launch (normally $10), paid once. Stockfish on up to 2,000 of your games, with an 8-week plan.
- Goat Pass: $5 a month or $39 a year. Lessons and puzzles built around the mistakes your games show; the first lessons are free.
- ChatGPT app: the Goat Pass course and your Goat Report inside ChatGPT.
What does the free Goat Card show?
The Goat Card is free. Type any chess.com username at trychessgoat.com/u/ and in a few seconds you see that player’s habits from their clocks and results: tilt after losses, time trouble, best and worst hours, their nemesis. No engine, no sign-up, no email.
From your Goat Card you can also click any of your games for a free Stockfish game review: accuracy, inaccuracies, mistakes, blunders and best moves, with no account and no daily limit. The review runs in your browser; phones get a quicker pass.
What is in a Goat Report, and what does it cost?
The Goat Report costs $5 at launch (normally $10), paid once. It runs Stockfish, the free open-source chess engine, on every move of up to 2,000 of your games. It ranks the mistakes you repeat by the rating points they cost you compared with your opponents in the same games, cuts puzzles from positions in your own games, and gives you an 8-week plan. The link arrives by email about 1.5 hours after you pay. See a sample report.
What is Goat Pass?
Goat Pass is a subscription to the Chess Goat lessons and puzzles, at $5 a month or $39 a year. The course starts from the mistakes your own chess.com games show, and the first lessons are free. Puzzles come from the Lichess puzzle database. Start on the Learn page.
Can I use Chess Goat in ChatGPT?
Yes. The Chess Goat ChatGPT app teaches the Goat Pass course in your chat, starting from what your latest chess.com games show. Goat Pass members sign in with their Pass email, and their progress is shared with this website. Report buyers can bring in their Goat Report. Other AI assistants can connect to the Chess Goat MCP server; see For AI agents.
How are the numbers made?
Every claim in a report comes from your own games, and each report ends with a method section: which games were analyzed, the engine settings, and how rating-point costs and trends were calculated. The games come from chess.com’s public data API, and the engine is Stockfish. If a report is wrong or never arrives, you get a full refund (refund policy).
The same method is used in public research on this site. Time pressure, measured runs Stockfish on 356,000 blitz moves by Nakamura, Carlsen, GothamChess and Botez, and shows how big mistakes rise as the clock runs down.
Where are the free guides?
The Improve pages are free guides for common spots: stuck at 1000, 1200 to 1500, tilt, time management, converting winning positions.
