## Description

Photograph a Go board, review every uncertain point, and score with Chinese or Japanese rules.

KifuLens turns a final Go position into a board you can verify and score.

PHOTO TO BOARD
• Take a photo or choose one from your library
• Adjust the four board corners before recognition
• Use free on-device recognition for 9×9, 13×13, and 19×19 boards
• Review highlighted uncertain intersections and correct any stone

SCORE WITH CONTROL
• Calculate with Chinese or Japanese rules
• Confirm dead stones explicitly before scoring
• Enter historical captures when Japanese rules require them
• Adjust komi and review a clear score breakdown

KEEP YOUR GAMES
KifuLens Pro is a one-time purchase that unlocks local game saving, the game library, SGF export, and sharing. Optional AI cross-check credits are separate from the free on-device recognition flow.

Photos are prepared on your device. KifuLens asks for your consent before any optional AI cross-check upload. Always review the editable board before accepting a score because glare, shadows, and camera angle can affect recognition.
