Questions

How is this different from KaTrain?

KaTrain is a full local desktop tool. Read19 focuses on opening a game in the browser and keeping the board, variations, and whole-game trend together. KaTrain can also connect to this cloud KataGo service.

Do I need to install KataGo or weights?

No. KataGo runs in the cloud. The client only shows the board and results.

Where are games and reviews stored?

Games stay on the device first. After you sign in, the Web, Windows, and Android clients also sync them to your Read19 library.

What is included in the free plan?

Free Beta includes 100,000 KataGo analysis units each month, up to 1,000 units per position, and 3 concurrent jobs.
