Interactive Story Planning

I've been using ChatGPT to help me work through the Story Genius method of story planning. I give ChatGPT summary of each step in the process with questions that need to be answered. Then I have it ask me questions about what I have in mind, and suggest improvements. I work on each step until it is what I envision, and then move on. ChatGPT helps with coaching, brainstorming, suggesting improvements, summarizing, and rewriting each step. Then, I move on to the next stage. I feel like this process gives me the control I need to be sure the story is following my vision. The new Story Engine is a BIG step in this direction. However, I'd really like to collaberate and work through each step before moving on to the next. Thanks!
