About this game

Go AI is a complete Go trainer - play, learn, and review the ancient board game
of Go (baduk in Korea, weiqi in China) with a real neural-network engine running entirely on your phone.

■ 4,121 TSUMEGO, ORGANISED BY THEME
Liberties, atari and capture, connect and cut, shape, snapback, shortage of
liberties, net, squeeze, semeai, life and death. Every Go problem comes with a
hint and a full explanation, so you learn the reason - not just the answer.

■ A REAL AI, FULLY OFFLINE
Go AI runs KataGo, a state-of-the-art neural network Go engine, natively on your
device. No account, no ads, no waiting for a server. Play Go on a plane, on
the subway, or anywhere you have a few minutes.

■ 12 KYU TO AMATEUR 4 DAN
Every rank from 12 kyu up to amateur 4 dan. Weaker levels don't just play slightly worse - they make the kind of mistakes a real player at that rank makes, so the game stays honest and instructive at every level. Three Human SL play styles: Modern, Traditional, and Varied.

■ REVIEW EVERY GAME
Step through any finished game move by move with a win-rate graph, see where the game turned, and check the top candidate moves. Your full history is saved locally.

■ BUILT FOR FOCUS
13x13 for a quick game, 19x19 for the full experience. Chinese rules, adjustable komi, undo, pass, resign, and move hints always within reach. Light and dark themes, stone sounds and haptics.

■ TRACK YOUR PROGRESS
Win rate, streaks, and a complete record of every game you have played.

■ PRIVACY
No account, no ads, no third-party analytics. The AI runs on your device, not in
a data centre, and your games are saved locally - they never leave your phone.
Everything works in airplane mode. No ads.

Whether you are learning Go from scratch, grinding tsumego to climb from 12 kyu toward amateur dan, or just want a strong offline baduk opponent in your pocket - Go AI is built for you.

Free to play with a daily game limit. One-time purchase unlocks unlimited games.
