What it solves

KaTrain is a tool designed for Go players to analyze their games and improve their skill through AI-driven feedback. It addresses the difficulty of identifying specific mistakes (costly moves) and practicing against opponents that match their own skill level.

How it works

The application integrates with the KataGo AI engine to provide real-time analysis. It uses the engine's evaluation to highlight mistakes with colored dots on the board, indicating the point loss associated with a move. It offers various AI personalities—ranging from full-strength professional level to calibrated rank bots and human-like models—allowing users to play against AI that mimics different styles or skill levels.

Who it’s for

Go players of all levels, from beginners who need immediate feedback on blunders to advanced players seeking deep analysis of variations and professional-style play.

Highlights

• AI-Driven Game Review: Automatically identifies the most costly moves in a game and generates focused SGF reviews.
• Teaching Mode: Provides instant feedback during play and can automatically undo moves that are significantly bad.
• Diverse AI Opponents: Includes calibrated rank bots, human-like models, and experimental styles (e.g., territory-oriented or center-oriented).
• Deep Analysis Tools: Features tools for exploring variations, calculating expected territory, and performing deeper re-evaluations of specific positions.
