What It Is

SmartGo One is a Go learning, playing, and study app from Smart Go, Inc. for Go players, available on iPhone, iPad, and Mac. It is not a general-purpose AI assistant, but a specialized tool built around Go use cases: learning the rules, practicing against the computer, reviewing games, solving problems, reading interactive Go books, and managing SGF game records.

Core Features

Its AI capabilities are powered by the KataGo engine, supporting games against the computer, undo, hints, territory estimation, and exploration of alternative variations during review. In the free version, computer play is limited to up to 13x13; the Pro version unlocks full 19x19 board play and analysis. The study features are a highlight: Pro includes more than 137,000 GoGoD professional games, searchable by player or year, and can perform pattern matching based on corner, side, or whole-board positions to show what professional players chose in similar situations. The problem sets, interactive books, and tree-style game record view also improve learning efficiency.

Pricing and Trial

SmartGo One is free to download. The free version includes game record and file features, over 100 professional games, more than 200 problems, sample chapters from 160 books, and 13x13 computer play. Pro costs $30/year and includes a 14-day free trial; it can also be unlocked with a one-time purchase of $99. Books and problem collections are one-time purchases, and purchases support Family Sharing.

Pros and Cons

Its strengths are its focused feature set and high level of Go specialization. KataGo, the professional game database, and pattern matching are very valuable for review and study. It also supports both Simplified Chinese and Traditional Chinese, making it relatively easy to get started. The drawbacks are that the full feature set depends on Pro, while books and problem sets require additional purchases; player biographies are English-only; the text does not state whether the AI runs locally, how privacy data is handled, or which payment methods are supported.

Who It’s For and Access from China

It is suitable for Go beginners, amateur dan/kyu players, teachers, review-focused users, and anyone who frequently works with SGF files. Access from China cannot be determined from the text alone. App downloads, subscription payments, and iCloud sync may be affected by the device account and network environment. Alternatives include Sabaki, Lizzie, KaTrain, AI Sensei, OGS, as well as domestic Go learning and playing apps.
