Controls for your screen On iPhone, select an intersection, then confirm with Play move. On iPad, one tap places a stone. With a mouse or trackpad, check the stone preview and click to play. Share a game image or record when you choose.

Analysis on your device KataGo models download to your device and run using WebGPU or the CPU. Internet access is required to load the initial page and download a model. Stored models are reused, but may need downloading again if device storage is cleared. Offline cold launch is not guaranteed. Speed and search depth depend on your device, model, settings and position.

Understand the estimates Win rates, score differences and ownership are AI estimates, not a final score or a guarantee of the best move. Check dead stones and territory when scoring. Follow the rules of any online Go service when using analysis tools.

No account, advertising, subscription or in-app purchases. Available in Korean, English, Simplified Chinese, Traditional Chinese, Japanese, French, German, Russian, Spanish and Polish. The app starts in a supported device language; you can change it in Settings.
