The only use A.I truly has in writing, at least for the very near future, is checking continuity, and making illustrations for those of us that can’t afford to pay an artist. A.I quiet literally isn’t made with the memory capacity it would need to even begin to give you anything other than regurgitated information—and the whole point of reading and writing is the creative aspect (for a lot of us anyway)
A.I will miss things if you write at any great length, even simple spelling and grammatical errors/typos. If you actually research how LLM’s work, it’d be really obvious. Imagine having termites in your house, and the exterminator clears 1 room, and then half of whatever else was relevant after that room. It’s not efficient.
Like I said though, for things like checking continuity, it can be great. I had to maintain almost 100 lore entries, and it was so much quicker to check for contradictions and update information with A.I. Yes, I can ctrl+f for a lot of things, but for the lore entries intrinsically tied to 2 or 3 other lore entries—let me just say that I haven’t had such strong continuity until I figured that out. I don’t have to worry about overcooking the lore books, or forgetting anything, because it’s easy to make mini-lore books from your bigger lore books when it’s relevant. I’m saying lore books, but it applies to outlines, canon, etc. I usually generate my notes and continuity into audio format and listen to them while either writing or multi-tasking, jotting down a quick note if something got twisted. (It’s hard remembering who the Queen’s sister’s husband was 100 years ago but it’s super relevant eventually)
