ChatGPT chess analysis and coaching: what really works
ChatGPT explains chess ideas well, but on its own it is not a chess engine: it can give a wrong verdict with full confidence, and it only sees the games you paste. Chess X-Ray runs Stockfish on powerful machines to check your chess.com or Lichess games, then turns the answer into a short video lesson on your own positions, not another wall of text.
Ask about your gamesCan ChatGPT analyze chess games?
Partly. Paste a PGN and ChatGPT will walk through the game, name the opening and describe the plans. That part is often useful, because it puts ideas into plain words.
The weak point is precision. A language model predicts text, while an engine such as Stockfish calculates the position. So ChatGPT can praise a move that loses a piece, or invent a threat that is not on the board, in the same confident tone as when it is right.
What ChatGPT does well, and what it gets wrong
- Good: explaining a concept in plain words, such as a pawn break or a weak square.
- Good: turning your goals and your schedule into a study plan.
- Good: answering follow-up questions, as many as you want.
- Risky: saying which move was best in a sharp position.
- Risky: long variations, where a piece can end up on a square it cannot reach.
- Missing: your history. It only knows the games you paste, so it cannot see the habits that come back from game to game.
ChatGPT chess coach prompts to try
These prompts keep it on what it does well. Give it the engine’s verdicts rather than asking for its own, and check any concrete move on a board.
Here is my game as a PGN. I played White. Without judging precise moves, tell me the three moments where the plan of the game changed, and ask me what I was thinking at each one.
Stockfish says my move 18 lost the advantage and the better move was the one I paste below. Explain in plain words, for a player rated around 1200, what idea I missed.
I am rated around 1200 and I have 30 minutes a day. Build me a one-week chess study plan, and ask me three questions about my games first.
Why one pasted game hides your habits
A mistake made once is bad luck. A mistake made every week is a habit, and a habit does not show in a single game. You would have to paste your games one by one and remember that today’s position is the one you lost last month.
To coach you, the answer has to start from all your recent games, with every move checked, and then be explained in plain words.
ChatGPT vs Stockfish for chess analysis
They do two different jobs. Stockfish calculates: it searches the position and finds the best move, but it gives you a number and a line, not an explanation. ChatGPT explains: it writes in plain words, but it does not calculate the position.
A good chess analysis needs both, in the right order: the engine decides what is true, and only then do words explain why.
Stockfish on powerful machines, on your own games
Chess X-Ray runs Stockfish on powerful machines, not on your phone. That is what lets it go through your recent chess.com or Lichess games, not just one, and find the moments that keep coming back.
Every claim is checked before it is said: when the lesson says a move loses a piece, the engine has confirmed the line. Then the explanation is written from those verified moves, so the words cannot drift away from the board.
A video lesson, because written lessons are hard to digest
ChatGPT answers with text, and so do most AI chess apps: long reports and written lessons full of notation, which you have to read, picture and replay on a board by yourself.
Chess is something you see. That is why Chess X-Ray generates a video: the pieces move on the board while a voice explains why, on your own positions. It is the most playful format to learn from your games, and short enough to watch before your next one.
ChatGPT or Chess X-Ray: which one for what?
- Use ChatGPT to explain a concept, build a study plan or ask follow-up questions about an idea.
- Use Chess X-Ray to know what is really costing you points: your games, checked by Stockfish, explained in a video.
- ChatGPT needs a pasted PGN. Chess X-Ray only needs your username: no password and nothing to install.
- ChatGPT gives you text to read. Chess X-Ray shows you the move you played, the better one, and a voice that explains why.
How it works
- Type your username
chess.com or Lichess. No password, nothing to install: we read your public games.
- Ask your question
In your own words, or pick one of the examples: your last blitz session, an opening, a habit.
- Watch your video
Your own positions, the move you played and the better one, with a voice that explains why.
Questions
Can ChatGPT analyze my chess games?
Partly. Paste a PGN and it can talk you through the plans and ideas of a game. Without a chess engine behind it, its verdicts on precise moves can be wrong, so check them on a board. Chess X-Ray checks your moves with Stockfish before it explains anything.
Is ChatGPT a good chess coach?
For explaining a concept, building a study plan or asking the same question ten different ways, yes. For telling you which move was wrong and why, not on its own: a coach has to know your games and be right about the moves.
Can ChatGPT play chess?
It can play moves, but it is not built for it. Public tests of older models report illegal moves and informal rating estimates, and there is no official rating. A chess engine such as Stockfish plays far stronger.
Does ChatGPT use Stockfish?
Not in a normal chat. It answers from what it learned, without calculating the position with an engine. Some setups connect an engine as a tool, but then you have to build that yourself. Chess X-Ray runs Stockfish on powerful machines for you, on your own games.
How do I analyze a chess game with ChatGPT?
Paste the PGN, say which color you played and ask about plans rather than precise moves. Then check every concrete move on a board with an engine. To skip those steps, give Chess X-Ray your username and ask your question.
What is the best alternative to ChatGPT for chess analysis?
One that calculates the moves and knows your games. Chess X-Ray reads your chess.com or Lichess games, checks them with Stockfish and answers with a short video lesson, so you see the moves on the board instead of reading about them.
Is there a Chess X-Ray app inside ChatGPT?
It is on its way. In the meantime, ask your question on chessxray.com: you get the same video on your own games.
Do you need my chess.com or Lichess password?
No. We read your games through the public chess.com or Lichess API, using your username. We never ask for your password.
What can I ask?
Anything about your own games, in your own words: your last blitz session, an opening that keeps losing you points, why you fall apart when the clock runs low, the mistakes in your endgames and what you missed.
