I don't use ChatGPT for scene creation, but for creating stat blocks for minor NPCs. My scenes are all handwritten in a notebook unfortunately. I keep telling myself someday I will digitize them into PDFs/modules, but I'm at about 3 years of content right now 😬
There are a few good creators on r/battlemaps that have patreon subs available (with many freebies too on that subreddit). I also have purchased dungeondraft, but as of yet have not delved into creating my own maps. I generally find something "close enough" and then tell my players what specifically is different in the scene should it come up.

That series took me something like 5-6 years to read, broken in the middle with Game of Thrones. WOT gets extremely dry by book 9 and Robert Jordan is tied up in something like two dozen plot lines with no way out.
I only finished the series because I was overseas with nothing to do except listen to audiobooks on my time off for a year and a half. The last 3-4 books being written by Brandon Sanderson was the best thing that could have happened to the series.
