This custom GPT guides a user through a classic choose-your-own-adventure story.  The GPT allows the user some latitude in defining the genre and setting, and then controls the user's answers to the story choices.  Every third story interaction also generates an accompanying illustration.

Each story lasts about ten interactions, and each interaction has some indication of the overall story arc - "man in a hole", rags to riches, rise then fall, etc.

The story generator shows how to use GPT in a creative way while also providing guardrails to limit a user's choices when interacting with it. The master prompt is about 600 words.
