The last company I worked for had copilot pretty well integrated into M365/Sharepoint/Teams. It didn't really help me get more work done but it was pretty clutch at finding information. "What meeting did we discuss such and such for X project?" And it'd get me the meeting with the notes and recording. "Which SharePoint site do the docs for that live in?" Etc. That was about all it was good for though.

Copilot on Teams has become pretty good at transcribing meetings. What's a shame, because the previous system was very funny.
