It seems to mostly be replacing work that is both repetitive and pointless. I have it writing my contract letters, ‘executive white papers’, and proposals.

The contract letters I can use without edit. The white papers I need to usually redirect it, but the second or third output is good. The proposals it functionally does the job I’d have a co-op do… put stuff on paper so I can realize why it isn’t right, and then write to that. (For the ‘fluffy’ parts of engineering proposals, like the cover letters, I can also use it.)
