Yesterday (show-and-tell with SO) I ran some of the AI Writing Tools on a few Notes I had (draft letters written, multiple paragraph docs, etc.) and I appreciate the functionality much more, now.
I don't know about compute-generated stuff, but using the in-built tools to refine and act-upon Content that I have personally created holds some definite plusses.
CIP: I had a tab-separated Materials/Labor doc I made for a Client last year, and I was able to plop it into a Table. Unfortunately, not all of the original data (namely, some of the most important parts) was included in the resulting matrix, so it looks like this is a WIP.
OTOH, AI Writing Tools did a decent job of re-fining old draft letters upon which I tried it.
