ChessWOW Stockfish 19 Analysis

ChessWOW turns a chess position from a photo, a screenshot or a book diagram into a board you can analyze. Stockfish 19 runs on your phone, so play, analysis and scanning work without an internet connection.

SCAN A POSITION
• Take a photo with the camera, choose an image from your gallery or paste a screenshot from the clipboard.
• Recognition runs on your device.
• Drag the corner markers onto the board edges, rotate the photo, choose the side to move and correct single pieces by tapping.
• Check castling rights and en passant before you analyze.
• Good sources: chess books, videos, puzzles and your own finished games.

ANALYZE WITH STOCKFISH 19
• Full NNUE network, offline on your device.
• Evaluation bar, the best move as an arrow and up to three lines.
• Evaluation in pawns, with the search depth always visible.
• The analysis shows the name of the opening.
• Optional Syzygy endgame tablebases for up to five pieces, downloaded on request.

GAME REPORT
• Accuracy for both sides, an evaluation graph and the critical moments of your game, explained in plain words.
• Every move gets a class: book, best, good, brilliant, inaccuracy, mistake or blunder.
• Retry the critical moves: play the position again and look for the better move.
• The report counts how many of your moves were opening theory.
