Chess Notation Analysis T

Chess Notation 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 v1.5:

Audio Time Alerts – Get spoken countdown warnings at customizable thresholds (30s, 10s, 5s, 3s, 2s, 1s) so you never lose on time.

Free Lichess Analysis – One-click export of your Chess.com games to Lichess for free computer analysis, with automatic board orientation.

Because everything runs locally in your browser, no personal data is collected or transmitted.

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 extension popup to pause, change highlight duration, enable audio alerts, or analyze on Lichess.

Who it's for:
Beginners mastering algebraic notation
Players who want audio time warnings without premium subscriptions
Anyone who wants free game analysis on Lichess
Coaches & students reinforcing move-to-notation connections
