Chess Helper is a browser extension for Chrome, Edge, and Firefox that overlays chess analysis features on Chess.com and Lichess.org, helping players see attackers, hanging pieces, checks, engine evaluations, and more without leaving the game page.
What is Chess Helper?
Chess Helper is a browser extension that enhances chess gameplay on Chess.com and Lichess.org by providing real-time visual cues and engine analysis. It takes the current board state from either platform and produces highlighted squares for attackers, hanging pieces, checks, and pinned pieces, as well as optional engine-calculated best moves and user-drawn arrows. The extension is developed by an independent team and is available via Chrome Web Store, Microsoft Edge Add-ons, and Firefox Add-ons.

- Arrow Visualization — Draw freehand arrows on the board to explore tactics and see updated board state after hypothetical moves.
- Engine-Calculated Best Moves — Built-in stockfish-like engine suggests top moves with evaluation scores, displayed as colored arrows.
- Fully Customizable — Toggle engine features, highlight styles, and timing preferences via a settings panel.
- Cross-Platform Support — Works identically on Chess.com and Lichess.org, including live games, bot games, and puzzles.
