Chess Goat

Your chess coach, in ChatGPT and Claude

Chess Goat teaches chess right in your chat. It reads your latest chess.com games, picks the lesson you need most, and teaches it on an interactive board: you play the moves, it checks them, gives hints one at a time, and never shows the answer before you try. The same coach works in ChatGPT and in Claude.

What can you ask it?

“Teach me the chess lesson I need most. My chess.com username is …” It looks at your recent games first and starts from a habit they show.
“What kind of player am I?” Your free Goat Card: your archetype, three habits with numbers, a stop-loss rule and your rivals.
“How did my last games go?” or “Which openings score best for me?” Your recent results and openings, from chess.com.
“Continue my course.” Picks up where you left off, even in a new chat. Progress is shared with the website.
“What does my report say about my endgames?” If you bought a Goat Report, connect it and work from its findings.
