I created a GPT to answer DW questions. In my testing it's pretty good about not getting confused with DnD rules (which regular ChatGPT does). I'm organizing my first DW game as a GM and I'm planning to use it to help me out.
Some good prompts for it:
How much XP does a character need to level up?
How do I resolve damage from multiple NPCs attacking the character?
Suggest 3 monsters the party might encounter in an evil wizard's castle
