Stockfish Helper Chess

Stockfish Helper Chess adds a lightweight panel on Chess.com to help you analyze positions quickly. It detects the board, reads the current position in FEN format, and displays Stockfish’s suggested best move with SAN notation and evaluation score.

You can adjust the analysis depth directly from the panel. It is designed for post game review, study, and training purposes only.

Do not use this extension during live or rated games. Using an engine while a game is in progress violates Chess.com’s fair play policy and may result in account penalties, including suspension or permanent ban. Always respect the platform rules and use this tool responsibly for analysis outside of active play.
