I've been using AI to help me write some short stories. Now, I'm not releasing these short stories but I do enjoy writing something quick and then asking ChatGPT and Gemini their perspectives on it.
I think using the LLM's to help you create dialogue, scenarios and settings can help bridge the gap when some of us experience writers block. Its an interesting thing to create a character and then tell the AI to give you a perspective by giving the AI their own personality traits to follow. Sometimes I'll create an entire character biography and get the AI to follow some dialogue and see if that character behaves as they should according to their biography.
There are so many ways to bring characters, dialogue and events to life using ChatGPT. I'm really impressed.
