When you are in the chat you go to the room #titan. This is the playground for AI.
There, you have the official bot, called Lira Firehand. I recommend the other bots. For stories the "The Fighting Pit" is ideal. Well, but you need to read the instructions first. It is good to know some basics about AI. If you know how to use the bots then they can create really good stories. You type in the commands and the bot will answers with 5-10 sentences.
Sometimes the bots are under maintenance. Then, it takes some minutes until they recover.
