## What it is
KaTrain is a cross-platform desktop application for playing and analyzing the game of Go (Baduk/Weiqi) with AI feedback powered by KataGo. It helps players review games, identify costly mistakes, and train against a variety of weakened AI opponents with different styles.

## Use cases
- review my go games to find my biggest mistakes
- play against a go AI with instant feedback on bad moves
- practice baduk against weakened AI opponents of different styles
- generate SGF reviews of my weiqi games automatically
- analyze go game records with kataGo
- train to improve my go rank with AI teaching
- retry moves when I make mistakes playing against AI

## When to choose
- you want a user-friendly GUI for KataGo-based Go analysis and training
- you want to play against varied weakened AI opponents with immediate mistake feedback
- you want automatic SGF game reviews highlighting point-losing moves

## When to avoid
- you need a headless KataGo engine for programmatic use rather than a GUI app
- you need analysis of other board games or chess
- you need a web-based or mobile Go client
