I do a ton of voice dictation, and the notes are usually haphazardly written and rife with structural and semantic issues.

With the appropriate prompt I can literally just toss the entire block of text into chat GPT and it will spit out a polished structured version of my original transcript, I've probably saved dozens of hours already.

It does an excellent job summarizing and restructuring existing data.

I have heard people using it for fiction generation, but the results that I have seen are highly unimpressive and tend to be extremely formulaic. Impressive for a LLM but not for a good storyteller.
