I’ve used ai in general a few years ago as a companion till for writing seo optimized articles. It was ok at that time, and would do maybe 30% of the work I needed, but I would still have to go back in and make major edits or it would only pop out a sentence at a time so I would be contently prompting it.

My wife is a full time writer for a company and she uses it all the time to create emails and speeches. She says the leaks and bounds in actual usability is pretty insane. Like, one prompt can give her an entire speech.
