  description

  Get real-time chess AI analysis and coaching right inside Lichess and Chess.com (and other sites). Chessvia combines Stockfish 17 engine evaluation with AI-powered coaching that explains moves in plain English — not just raw numbers.
  
  What makes Chessvia different from other chess analysis tools:
  Unlike basic chess calculators that only show engine lines, Chessvia is an AI chess coach. It tells you what to do, what to avoid, and the key idea behind each position. Every analysis includes plain-language explanations you can actually learn from.
  
  Features:
  - Stockfish 17 evaluation running locally in your browser (fast, private, no server needed)
  - AI coaching that explains the best move and why it works
  - Position assessment: opening, middlegame, or endgame context
  - Candidate moves with explanations for each option
  - "What to do / What to avoid / Key idea" coaching breakdown
  - Ask your own questions about any chess position
  - Quick question chips for instant analysis
  - Best move arrows drawn directly on the board
  - Copy analysis to clipboard or have it read aloud
  - Works on Lichess and Chess.com analysis boards
  - Dark mode and light mode support
  - Keyboard shortcuts (Ctrl+Shift+C to toggle)
  - 100% free — no signup required
  
  How it works:
  1. Open any Lichess or Chess.com analysis board
  2. Chessvia automatically detects the position and runs Stockfish eval
  3. Click "Analyze" or ask a question to get AI coaching
  4. Learn from plain-language explanations of your chess positions
  
  Privacy & Fair Play:
  - Stockfish runs locally in your browser — your positions stay private
  - Only activates on analysis and practice modes, never during live games
  - TOS compliant — only activates on analysis modes, never during live games
  - No account required, no data sold
  
  Powered by Stockfish 17 and Chessvia AI
  
  Built for chess players who want to improve, not just see engine numbers. Whether you're a beginner learning chess fundamentals or an intermediate player studying openings and tactics, Chessvia makes chess analysis accessible and educational.
