I am one of the SE editors/regular contributors and I did play around with this a bit for a poetry collection: https://groups.google.com/g/standardebooks/c/IUvGLmvZrmM/m/s...

I'm sure someone sufficiently determined and good at prompt engineering, and integrating LLMs into a larger toolset, could come up with something even better. I'm personally very skeptical of LLMs as a technology, but even I have to admit that this was a pretty ideal and unobjectionable use of LLMs.

That being said, though it was a fun experiment, I later found that it was easier (and less wasteful of natural resources) to just do the same thing with a bit of custom markup and a search and replace script.
