GoYomi

GoYomi is a friendly place to learn Go.

Play 9x9 games against an AI that scales from beginner to strong while a coach watches every move, grades it, and explains what happened.

What you get:

• An opponent at your level. Nine AI levels from Pebble to Phoenix, all played by KataGo's neural network right in your browser.
• A coach that grades every move in plain language, and adjusts its explanations to your experience.
• It tells you when the AI's move doesn't need an answer, and warns you before you pass too early.
• Find better moves yourself: an optional mode that gives you another try after a mistake before the coach shows its move. Hints when you want them, with the reason the best move matters, and a look at what your opponent is planning.
• See the board like a stronger player with overlays for liberties, atari and territory. 
• Undo any move, try something else, and experiment freely. Scoring made simple. Pass twice and the coach counts the game. Review your games. A game graph with mistakes marked. Save and load SGF files.
• Accessible. Play with the keyboard alone, and hear every move and comment through a screen reader or built-in speech.
• New to Go? The rules are easy to learn and explained in the game.
