I’ll probably come back and add more details later on, but now here’s my basic workflow.
I don’t use AI as a creative writer. I’m sure with better prompting, I could get better results, but with what I’ve been doing using it for creative writing hasn’t produced the results I want. Plus, this is MY story, not ChatGPT’s. 
I’ll describe a general aspect of the plot, focusing on a specific scene… my chapters are ~3500 words each, so I break them down into chunks of 700 words to create several scenes. A short scene would be a single chunk, whereas my longest single scene is 3 chunks, if there’s a lot to cover.
I describe and discuss what happens in the scene in exhaustive detail - I might write 1500+ words to get 500 back - and what the AI returns is a basic structured outline of the scene. I have this up on one of my screens, and the Google doc on the other, and I write the next draft there… sometimes I write it to follow the outline, other times I go off in a completely different direction… when that’s done, if I don’t feel it flows as well as it could, or if it needs polishing in terms of grammar, ensuring tenses etc all match, I’ll feed it back into ChatGPT and ask it to tidy it up. There aren’t substantial changes at this point, it’s a gloss edit… I’ll do one more pass on this next iteration, and when I’m happy with it, that passage replaces the first draft in the google doc.
Occasionally I’ll do a deep dive into one aspect of the story just to ensure the details are at the level I want them at… there’s a mention in one scene of a book the main character is reading, and I wanted it to be highly symbolic of the story so I dove into themes of classic literature to find one where the struggles of the hero in that story paralleled the struggles my hero is facing, and ended up with a Russian book from a century ago that I’d never heard of before, but was a perfect choice. It’s a single quick mention in a 100,000-word book, but for someone who recognizes its significance, it will add depth to the plot.
Same thing for details of timekeeping; I spent nearly an hour discussing temporal perception for various spans of time as a computer would perceive them, to arrive at nothing more than a status display that the reader will see… overkill? absolutely. But when I do something, I consider the details. I don’t want to write something that someone with more knowledge than me will see and immediately scoff at how ridiculous or implausible it is.
Even so, I feel I’m making some good progress on this; I’m averaging about a chapter a week (with the time I’m able to devote to it… about an hour a day, after my daughter goes to sleep). The time is spent about half on actually building the scenes, and the other half refining plot elements and ensuring the different story arcs mesh together and leave as few plot holes as possible.
It’s a fun process, and at this rate, I fully expect to have a finished novel by the end of this year.
Even if I never try to publish, at the very least I can have a (via KDP) physical copy of a book on my shelf, and be able to say I created that. That’s MY story.
Definite bucket list project.
