Analyze your chess game for free
Paste a PGN or pick a recent game via your Chess.com or Lichess username: the analysis starts in seconds, free and with no account. Every move is graded by Stockfish, key moments are flagged on the evaluation graph, and the game’s number-one turning point — the one that actually decided the result — is explained in plain language: why it was a mistake, what you should have played, and the correct follow-up. Nothing to install and nothing uploaded to a server: everything runs in your browser, on desktop and mobile alike.
What the analysis does
Far more than an evaluation graph: every move is graded, your decisive mistake is isolated and explained in plain language — the work of a desktop analysis program, with nothing to install.
Engine evaluation of every move
Stockfish, the reference open-source engine, evaluates every position of the game — right in your browser. It is the same engine the big platforms rely on: a trustworthy evaluation of every move, with no queue and no cap on the number of games.
Every move graded
From brilliant to blunder, every move gets a clear grade. See at a glance the moments where the game was decided: the inaccuracies that pile up, the mistakes that turn the tide and the blunders that cost the game.
Your key moment
We pinpoint THE turning point — the exact moment your advantage flipped — instead of drowning you in dozens of comments. It is the one move worth remembering: the lesson you will still be using ten games from now.
The explanation, in plain words
One game is just the start
This analysis spots your mistake in a single game. ChessPivot goes further: import your games and it detects the recurring mistakes costing you rating, then gives you a plan to fix them.
Frequently asked questions
Is the analysis really free?
Yes, completely and with no limits: as many games as you want, with no account and no credit card. The full analysis — move grades, evaluation graph, explained key moment — is free. An account only becomes useful to track your recurring weaknesses across all your games.
Which chess engine is used?
Stockfish, the reference open-source engine, running in your browser — the same strength as the big sites' analysis. It is the engine the world’s best players use to prepare their games.
Are Chess.com and Lichess supported?
Yes. Enter your username and pick from your recent Chess.com or Lichess games, or paste any PGN — including an over-the-board game entered by hand. No login to your account is required: the username is enough.
Is my game stored?
No. The analysis is ephemeral: it runs in your browser, nothing is sent to our servers or stored. Close the tab and nothing remains — run the analysis again whenever you like, it is unlimited.
How is this different from Chess.com’s analysis?
Instead of a long list of moves, ChessPivot isolates your decisive moment and explains it in plain language. And across all your games, it detects your recurring weaknesses to help you improve: the difference between fixing one game and fixing your play.
How do I analyze a Chess.com or Lichess game for free?
Simply enter your username in the tool above, pick the game from the list and start the analysis: move grades, evaluation graph and an explained key moment, with nothing to install. You can also export the PGN from Chess.com or Lichess and paste it directly.
