Hello, I'm happy that you like it :) We did consider chatbot functionality, and would love to add it at some point! Using it as optional feature so people can use a model of their choosing would be the most sensible approach as it could be self contained and completely optional for people who don't want AI stuff in their game while also enabling the rest to chat with the characters.
I created one just now:

There are only donation tiers for now as i need to think of proper rewards that will provide fun benefits to members, also thank you for wanting to support what we do :)
For now it is set up as my personal one (the art, animation etc. guy) due to legal reasons.
