Capture a screenshot of a chess position

Step 1

Capture a Position

Take a screenshot of a finished game, a puzzle, a chess book diagram or a video, or snap a photo of a board. Make sure the entire 8×8 chessboard is clearly visible.

Step 2

Upload & Wait for Results

Upload or drag & drop the screenshot into the drop area above. The computer vision engine will automatically detect the board, identify pieces, and calculate the best move in seconds.

Step 3

Copy FEN & Open Analysis

Copy the detected FEN string or open it directly on lichess Analysis ↗ or Chess.com Analysis ↗ for deeper study. Check the side to move and use Switch Turn / Swap sides if needed, and Flip board next to the detected position to view it from the other side.
