Go! lets you play Go against AI directly inside ChatGPT, with no separate login required. Games use the professional and international tournament standard 19×19 board by default, while 13×13 and 9×9 boards are available whenever you request a shorter match. Choose to play Black or White, select from three AI difficulty levels, and use a handicap of 2 to 9 stones when you want to balance the game. Go! handles legal move placement and captures while enforcing the prohibition on suicide, ko, and repeated positions. During a game, you can pass, resign, or undo a move. When play ends, the board is scored using Chinese area scoring. The result clearly identifies the winner and uses standard notation such as B+12.5 or W+R. A detailed breakdown shows stones, territory, komi, and totals, with territory marked directly on the board so you can understand how the result was calculated. The complete interface is presented in English. Whether you search for Go, Baduk, Weiqi, or simply want to play Go without leaving ChatGPT, Go! provides a convenient, rules-aware way to start a match at your preferred board size and difficulty.
