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.
