Honestly all the GPT stuff they are introducing seems pretty useful.

I like the idea of having automatic tasks generated after a meeting. I usually jot down 'follow-up' items while in meetings, and send them out to relevant coworkers afterward. It would only save me 5 minutes or so after every call, but could maybe help me focus more on what's being said rather than writing everything down 🤷‍♂️.

Also flagging parts of a meeting that you missed, auto-chapters, and tagging sections by the speaker all seem genuinely helpful.

That being said, my company doesn't use Microsoft products, so I hope to see features like this come to other platforms.
