I just discovered AI Dungeon 2 for myself, if you don't know what it is, it's basically an AI director creating a text adventure on the fly based on your inputs, you can make it remember certain things, alter the story to fit you, write some story yourself and interact with the world within, once you get the AI to follow the path you want it can get very interesting.

I highly suggest playing it, it's free, you can find it play.aidungeon.io (you need and account to enable NSFW stuff).
