Highlights chess notation, alerts you on low time, opens a free game review, and checks your opponent for cheating. Chess Helper brings standard algebraic chess notation (SAN) to life directly on your board, no more switching back and forth between moves and notation. As you play on Chess.com or Lichess.org, this extension automatically: 1) Detects each move in real time 2) Highlights the destination square with a subtle overlay grid 3) Displays the SAN (e.g. Nf3, exd5, O-O) on that square, then fades out Handles castling, pawn promotions, captures and disambiguations seamlessly. New in v1.8: Free game review: On a finished Chess.com game, one click opens a full review on freechessreview.com, with accuracy, move badges (best, mistake, blunder, brilliant) and engine lines. Stockfish runs in your own browser, so there is no daily limit and no account. Also included: Check your opponent: One click opens a free statistical report for the player you are facing, with their username and the time control (blitz or rapid) already selected. Audio Time Alerts: Spoken countdown warnings at customizable thresholds (30s, 10s, 5s, 3s, 2s, 1s) so you never lose on time. Everything runs locally in your browser. The extension collects no personal data and transmits nothing on its own. The game review and the opponent check simply open a link when you click them: the review link carries your game's moves in the part of the address that browsers never send to a server, and the opponent check carries your opponent's public username. How it works: 1) Install and enable the extension 2) Navigate to any live game on Chess.com or Lichess.org When you (or your opponent) move a piece, watch the board highlight the landing square and show its notation, instant feedback that helps you learn SAN while you play. Open the extension popup to pause, change highlight duration, enable audio alerts, review your finished game, or check your opponent. Who it's for: Beginners mastering algebraic notation Players who want audio time warnings without premium subscriptions Anyone who wants an unlimited free game review Coaches & students reinforcing move-to-notation connections Install Chess Helper today and level up your chess experience!
