About CAISSA Chess

AI-powered chess analysis for everyone

Our Mission

CAISSA Chess exists to democratize chess analysis. We believe every chess player, from beginner to master, deserves access to powerful, intuitive tools for improving their game.

Traditional chess analysis tools are either too expensive, too complex, or too limited. We're building a free, open platform that combines the power of Stockfish with modern AI to make chess analysis accessible, educational, and enjoyable.

Your privacy matters. Here's how we handle your data:

  • No Tracking – We don't use Google Analytics or third-party trackers.
  • Open Source – Our code is transparent and auditable on GitHub.
  • Your API Keys – AI Mentor uses your own API keys. We never store them permanently.
