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 analyzer — chess.com/game/live/… and lichess.org/… URLs load straight into the review. You can even just swap the domain to ours.
We fetch your ten most recent public games from Chess.com or Lichess. Public games only — no password, no OAuth.
Tap the one that stung. The engine walks every move at full depth — the same pass signed-in members get.
Accuracy, blunders, the turning point, and a plain-English “why the better move wins” for each mistake.
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.
No. Reviews run for guests. Rate limits apply so the engine stays fast for everyone; signing in raises them.
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.
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.
