To analyze a Chess.com game with AI: open the game, export the PGN via the share menu, then paste it into a free AI chess coach like Chess Masti AI. You'll get Stockfish evaluation plus natural-language explanations of every critical move — without using your Chess.com Game Review quota or paying for Diamond. The engine runs in your browser; the game data never has to leave your device for the analysis step.
Open the finished game on Chess.com
Go to chess.com/games/archive (or your profile → Games) and click into the game you want to review. Any time control works — bullet to daily.
Export the PGN
Below the move list, click the share icon (or "..." menu on mobile). Choose "PGN" and either download or copy. You can also append /pgn4 to the game URL on desktop to grab the PGN directly. PGN format is universal — every analysis tool reads it.
Open Chess Masti's analysis board
Free, no login required. The board accepts a PGN, FEN, or starts blank. Paste the PGN from step 2. Stockfish starts evaluating in your browser immediately — your game stays on your machine for the engine work.
Walk through the critical moves
Click forward through the moves. At each significant evaluation swing the AI coach explains what happened in plain language: what your plan was, where the mistake came in, and what the right idea was. Claims are validated against Stockfish before they're shown, so the coach doesn't make up moves.
Ask follow-up questions
If you don't understand why a move was bad — "is g6 always weak here?" or "why couldn't I take the bishop?" — ask in plain language. The chat holds the whole game in context, so you can reference earlier moves without re-explaining.
Drill the patterns you missed
Your biggest blunders become puzzles automatically. Practice the exact positions until the pattern sticks. This is what actually moves your rating — explanation without practice is comfort food.
Chess.com's built-in Game Review is solid and stays in-platform. The trade-offs: some features are gated behind a Diamond membership, and the free tier limits how many reviews per day. If you want unlimited reviews without paying, exporting the PGN to a free external AI coach is the cleanest path.
The engine work is comparable either way — both use Stockfish. What you're trading is in-platform convenience for unlimited free use plus, in Chess Masti's case, a training loop that turns blunders into puzzles.
Pick the loss, not the win.
Wins teach less than losses. Analyze the games you wish you could replay.
Bring your reasoning.
If you remember what you were thinking on the move that lost the game, type it into the chat. The coach can respond to your actual logic instead of guessing.
Convert the worst blunder to a puzzle.
One drill per game review keeps the habit lightweight. The pattern repetition is what actually compounds.
