Analyze your chess game for free
Paste a PGN or pick a recent game via your Chess.com or Lichess username. The analysis runs in your browser: every move is graded, key moments are flagged on the graph, and the game’s number-one turning point is explained.
What the analysis does
Far more than an evaluation graph: every move is graded, your decisive mistake is isolated and explained in plain language.
Engine evaluation of every move
Stockfish, the reference open-source engine, evaluates every position of the game — right in your browser.
Every move graded
From brilliant to blunder: see at a glance the moments where the game was decided.
Your key moment
We pinpoint THE turning point — the exact moment your advantage flipped — instead of drowning you in dozens of comments.
The explanation, in plain words
Not just a raw engine number: we explain why it was a mistake, what the best move was and the line you should have played.
Your game at a glance
Accuracy, your moves broken down by category, the phases where you slip: a full overview on a single screen.
Free and private
No account required, unlimited analyses. Everything runs in your browser: your game is never uploaded or stored.
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. No account is needed to analyse a game.
Which chess engine is used?
Stockfish, the reference open-source engine, running in your browser — the same strength as the big sites' analysis.
Are Chess.com and Lichess supported?
Yes. Enter your username and pick from your recent games, or paste any PGN.
Is my game stored?
No. The analysis is ephemeral: it runs in your browser, nothing is sent to our servers or stored.
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.
