Chessvia AI — Chess AI That Explains Your Moves Get real-time chess AI analysis and coaching right inside Lichess, Chess.com, Chessiverse, and more. Chessvia combines Stockfish 17.1 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 17.1 evaluation running locally in your browser (fast, private, no server needed), AI coaching that explains the best move and why it works, position assessment covering opening/middlegame/endgame context, candidate moves with explanations for each option, a "What to do / What to avoid / Key idea" coaching breakdown, the ability to 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, supports 6 chess platforms, dark and light mode support, keyboard shortcuts (Ctrl+Shift+C to toggle), and it's 100% free with no signup required. How it works: Open any bot/AI game, puzzle, or analysis board on supported sites. Chessvia automatically detects the position and runs Stockfish eval. Click "Analyze" or ask a question to get AI coaching, then learn from plain-language explanations of your chess positions. Privacy & Fair Play: Stockfish runs locally in your browser so positions stay private. It only activates on analysis and practice modes, never during live games. TOS compliant with all supported platforms. No account required, no data sold. Powered by Stockfish 17.1 and Chessvia AI. Built for chess players who want to improve, not just see engine numbers.
