Our Mission

Sachess was founded on a simple idea: everyone who takes chess seriously should have access to professional analysis tools without paying or installing complex software. We built this platform on the open-source Pikafish engine, enabling AI analysis to run directly in the browser.

Our goal is to lower the barrier to chess analysis. Whether you want to review your games, study opening theory, or practice endgame techniques, Sachess provides powerful support. All features are completely free, with no ads and no paywalls.

  • Professional analysis tools, completely free.
  • Built on open-source engine, technically transparent.
  • Runs directly in browser, no installation needed.

Technical Architecture

Sachess uses the Pikafish engine for AI analysis, a Chinese chess engine based on Stockfish that runs in the browser via WebAssembly. This means all computation happens on your device—your game records are never uploaded to servers.

We also integrate the ChessDB cloud book to provide practical game data. Combining engine analysis with cloud book data gives you a more comprehensive perspective for understanding positions.

  • Pikafish engine, based on Stockfish technology.
  • WebAssembly enables in-browser execution.
  • ChessDB cloud book provides practical game data.
