Sure. Here is the fanfiction book I've been using LLMs to help me write. Helps a lot with improving prose and identifying plot holes. It's much better then a rubber duck for talking out how to improve a chapter and write plausible story arcs. It's not great at word smithing, but I find it errs on the side of too many similies and metaphors, so I just delete some of them as I copy the suggestions over into my draft.
