I also use it for that pretty often. I always double check and usually it's pretty good. Once in a great while it turns the summary into a complete shitshow but I always catch it on a reread, ask a second time, and it fixes things up. My biggest problem is that I'm dragged into too many useless meetings every week and this saves a ton of time over rereading entire transcripts and doing a poor job of summarizing because I have real work to get back to.

I also use it as a rubber duck. It works pretty well if you tell it what it's doing and tell it to ask questions.
