  description

  Elevate your game with an AI chess companion that doesn’t just show you the moves—it teaches you the "why" behind them.
  
  Stop staring at engine lines you don't understand. Glassfish sits alongside your lichess.org analysis board to provide real-time, conversational analysis. Whether you’re stuck in a complex mid-game or trying to convert an endgame advantage, Glassfish acts as your personal coach, offering everything from subtle nudges to deep strategic breakdowns.
  
  Key Features
  💡 Intelligent Hints: Not ready for the answer? Get a tactical nudge that points you in the right direction without spoiling the solution.
  
  🎯 Move Reveal & Explanation: See the best move instantly, accompanied by a natural language explanation of the strategy, threats, and long-term goals.
  
  💬 Interactive Chess Chat: Have questions about a specific line? Ask the AI! "Why is the Bishop better than the Knight here?" or "What happens if I push my h-pawn?"
  
  🧠 Context-Aware Analysis: Our AI understands the nuances of your specific position, providing human-like insights that standard engines miss.
  
  ⚡ Seamless Integration: Works quietly in your sidebar, ready to assist whenever you need a second pair of eyes.
  
  Why use Glassfish?
  Standard engines like Stockfish are incredibly powerful, but their "advice" is often just a string of numbers. Glassfish attempts to translates those numbers into actionable concepts, helping you recognize patterns and improve your board vision for your next match.
  
  Perfect for:
  - Beginners looking to understand basic tactics.
  - Intermediate players stuck on a plateau.
  - Anyone who wants a more "human" way to review their games.
  
  How to Use
  - Open the analysis board on a game on lichess.org.
  - Click the Glassfish icon in your extensions bar.
  - Use the Hint button for a nudge, or keep chatting to dive deep into the position!
  
  Disclaimer: Please use Glassfish responsibly. This tool is designed for post-game analysis and learning. It does not work on anything except the lichess.org analysis board. Always follow the fair play terms of the platform you are playing on.
