A new version of KaTrain has just been released. It’s a tool you can use to review your games more effectively, as well as play teaching games against AI. It contains a number of weaker AIs calibrated for 1-10k players which are also the foundation for some of the bots on OGS which have been challenged over 12,000 times in the last few months.
This version has a complete UI redesign, thanks to great help from @kameone, as well as translations into Korean and French. A few volunteers have already contacted for help in supporting more languages, but do let me know if you can contribute.
