I use LLMs in my fiction writing; and before the wolves come out to shred me to pieces: The LLM never gets to see my writing and doesn't do any of the writing for me. I use LLMs in other ways.

One of the first uses I discovered was to have it identify my own blandness. I'll give it a general scenario from my writing and ask it for ten resolutions to that scenario. If my own resolution appears, I realize at best my resolution is bland and at worst cliche.

This is eerily similar to something I do with Hacker News stories that hit the front page. I run the post against a couple of LLMs (Mixtral, GPT-OSS, Qwen3, etc.) with the directive to produce a set of 20 of the most likely top-level replies.

I then wait a few days, and then use a couple of systems (embeddings, deBERTa, etc.) to rank comments by novelty against the LLM-produced replies.
