Free chess game review — every mistake, explained in plain English

Type your Chess.com or Lichess username and pick a game. ChessAdept runs a full engine pass and shows your accuracy, the moment the game turned, and what to study next. No account. No trial. Nothing to install.

…or paste a game link into the analyzerchess.com/game/live/… and lichess.org/… URLs load straight into the review. You can even just swap the domain to ours.

How it works

  1. Type your username

    We fetch your ten most recent public games from Chess.com or Lichess. Public games only — no password, no OAuth.

  2. Pick a game

    Tap the one that stung. The engine walks every move at full depth — the same pass signed-in members get.

  3. Read your review

    Accuracy, blunders, the turning point, and a plain-English “why the better move wins” for each mistake.

What the review includes

Questions, answered honestly

Is it actually free?

Yes. The review is ChessAdept's front door, not a teaser — the same engine pass, accuracy model, and explanations signed-in members get. An account adds the training loop on top: puzzles from your own blunders, opening drills, and progress tracking.

Do I need an account?

No. Reviews run for guests. Rate limits apply so the engine stays fast for everyone; signing in raises them.

Which sites are supported?

Chess.com and Lichess — by username, by pasted PGN, or by game link. Daily and live games both work. See the site-specific guides: Chess.com game review · Lichess game review.

Will the accuracy match the number Chess.com shows me?

Very nearly. For Chess.com games we show Chess.com's own score when it exists, and otherwise a calibrated estimate fitted against thousands of their scored moves — typically within a few points, and labelled either way.
