Chess.com Local Eval (Stockfish) tekijä CTP

Chess dot com local eval provides private, on-device post-game analysis for completed Chess.com games in Firefox.

Features:

• Bundled Stockfish WebAssembly engine—no cloud analysis
• Evaluation graph and evaluation score bar
• Best move and principal variation
• Blunder, mistake, inaccuracy, good, and conservative brilliant labels
• Move navigation and board synchronization
• Board arrows, highlights, and move-quality icons
• Selectable Stockfish depth from 8 through 18
• No account, analytics, telemetry, remote API, or paid Chess.com endpoint

For fair play, engine analysis is unavailable while a game is live or in progress. Review becomes available only after the page exposes a definitive game result or the completed game is opened in Chess.com’s analysis view.

All calculations happen locally on the user’s device. Game moves and analysis results are not transmitted anywhere.
