Everything You Need to Improve at Chess
Comprehensive chess training tools designed to help players of all levels analyze games, practice tactics, and develop winning strategies.
Puzzles Made From Your Own Games
Most puzzle trainers give you random positions. Caissablanca analyzes your actual Chess.com and Lichess games to find the moments where you went wrong — then turns them into puzzles you can solve again and again.

- Puzzles generated from your real blunders and missed tactics

Frequently Asked Questions
Everything you need to know about Caissablanca and chess analysis.
We offer a free tier with 10 Caissa AI messages and 1 game per day, plus Stockfish analysis. For unlimited access to all features including game review, Chess.com integration, and unlimited Caissa AI messages, upgrade to Pro starting at $4.99/month.
Our pricing is designed to cover the cost of running advanced AI models (LLMs) that power Caissa AI and our analysis features. We're committed to keeping Caissablanca as affordable and accessible as possible while providing high-quality coaching. The free tier ensures everyone can benefit from chess analysis, and Pro pricing simply helps us sustain the service.
Our Stockfish engine supports ELO ratings from 400 to 2800, making it suitable for complete beginners to advanced players. You can adjust the difficulty to match your current level or challenge yourself against stronger opponents.
Simply navigate to the Analyze section and use the Chess.com integration to fetch your recent games. You can also manually paste PGN notation or FEN positions for any game you want to analyze.
When you connect your Chess.com or Lichess account, we analyze your games with Stockfish to find positions where you made mistakes or missed tactics. These positions are turned into puzzles that you can solve repeatedly, so your training targets your actual weaknesses instead of random positions.
A Chess.com or Lichess account is needed for personalized puzzle generation, since the puzzles are built from your game history. However, you can still use Caissablanca to play against Stockfish, analyze positions via FEN/PGN, and chat with Caissa AI without one.
Caissablanca generates puzzles from your own games — not random positions — so every puzzle you solve targets a real weakness. Combined with Stockfish analysis and Caissa AI that explains moves in plain language, it's the most personalized chess training experience available.
