Which generative AI prompt do you mostly commonly use?

I mostly use it to improve the grammar and wording of things I've already written. Sometimes I'll ask it to rewrite it in a couple different professional styles. I usually use my original combined with parts that I liked from whatever it re-writes. There have been a couple times where I just went with the original because I thought GPT's re-write was poor, but I'd say 95% of the time it improves on something. 

First, paste a written work and ask it to improve grammar and reorganize structure in three other forms for ease or increased understanding.

Second, in context to the pasted material what other topics should I consider. A gap analysis.
