I have used AI often and i use it in combination with my fave world-building tool in the Game Unfolding Machine and Plot Unfolding Machine toolsets:

AI + PUM + GUM is what helped me get to grips with Solo RPGing. I don't blog about it too often on hive as I don't think there is a niche space for it, but I have been running a game for quite a while.
