Qiban: Go Coach & Lessons

Qiban (棋伴, "Go companion") is a Go coach that teaches while you play. The moment you make a mistake, it stops, shows you the better move and what follows right on the board, and lets you try again. Between games, learn from lessons written for Qiban, review every game move by move, and practise on drills made from your own mistakes. • Live coach: stops you at each real mistake, explains it on the board and adapts to your level • Lessons: opening, life and death, tesuji, shape and endgame, with board diagrams • Drills: your own mistakes become your practice • Game review: what each move gained or lost, your key mistakes and the better lines • A human-like opponent at your level, from beginner to strong amateur, that adapts as you improve • Study board: open any SGF or set up a position and see the AI's judgement • AI vs AI: watch networks play each other • In English, Français, 简体中文, 繁體中文, 日本語 and 한국어 Runs on your device: the Go AI calculates on your iPhone, iPad or Mac. No internet needed (stronger networks download once from Apple when you first choose them), no account, no ads, no tracking. Completely free: every lesson, unlimited reviews and unlimited study, on iPhone, iPad and Apple-silicon Macs (with the largest network on a Mac). No in-app purchases.
