Analyze with Chess Masti — the Chrome extension

One orange button, dropped into the top navigation of every Lichess and Chess.com game page. Click it. Your PGN comes with you to chessmasti.com and the AI coach is already talking. No copy-paste, no upload, no account.

Coming to the Chrome Web Store

We've submitted the "Analyze with Chess Masti" extension and it's in review. First-time reviews can take a few days to a couple of weeks. Check back, or follow @ChessMastiAI — we'll post the install link the moment review approves.

♟ Install — review pending

What you get

The whole point of the extension is to kill the friction between finishing a game and reviewing it. Right now, you finish a game on Lichess or Chess.com and the "Rematch" button is right there. So you click it. The blunder dies undiagnosed.

With the extension installed, a single orange ♟ Analyze with Chess Masti button sits in the top nav of every game page. Click it and a new tab opens at chessmasti.com with your PGN already loaded. Stockfish 17 evaluates in your browser; the AI coach starts a real conversation about your moves; the hallucination validator double-checks every claim. It's the post-mortem you keep meaning to do, in one click.

  2. Visit any game page on lichess.org or chess.com.

What the extension does not do

  • It does not collect personal information.
  • It does not track your browsing across sites.
  • It has no background script, no storage, and no remote server of its own.
  • It runs only on lichess.org and chess.com — no other sites.
  • It modifies those pages only by adding the single button.
  • It sends the PGN only to chessmasti.com, and only when you click — equivalent to copy-pasting the PGN into chessmasti.com yourself.

The full privacy disclosure for both this extension and the chessmasti.com website is at /privacy.
