Drag pieces to set up position or scan a screenshot · click "Analyze Position" to find the best move
Set up any chess position by dragging pieces onto the board, pasting a FEN string, or scanning a screenshot from Chess.com, Lichess, or a book diagram — the analyzer reads it automatically and finds the best move using the Stockfish engine.
Whether you're stuck on a tactical puzzle, working through an endgame, or want a second opinion on a position from one of your own games, pick a target playing strength from beginner to full engine power and get an instant, engine-backed recommendation.
Everything runs locally in your browser: no account, no cookies, and no paywall — the full analyzer is free to use for as long as you need it.
