my main LLM use case thus far has definitely been thesaurus. it's fun to be able to describe the sense of the word i want, not just spider a graph from some related word as with conventional thesauri. and it's nice to be able to ask for more options providing more hints about what i'm after. but it hasn't been a miracle. it only occasionally offers good candidate words i haven't already considered. most are inevitably bad choices or words i've considered. still, on net it's been helpful.
