For me it’s pasting a snippet of code I’m struggling to debug and asking it to help. Sometimes it works, sometimes it comes up with an answer that is also buggy or doesn’t work.

I find it much more useful for soft things like writing a complaint to a vendor for me, dealing with customer service, or cover letters from a job ad that I only have to slightly tweak. Takes me five minutes instead of 30+ and I got a few compliments about my “outstanding” cover letter.
