I wanted to test Copilot using some actual data, but not data from work. The docs I loaded are a mix of PDFs and Office documents, with embedded graphics, tables, and so on. Asking questions about e.g. stall speed is a proxy for asking fact-based questions from a corpus of "real" work docs.
Some of the features I'm most excited about trying, like meeting recap, aren't available to me unless I schedule a bunch of meetings in the sandbox, which I can't do because it's a sandbox where I don't have access to invite outsiders.
I will say that the integration and fit/finish of Copilot throughout M365 is quite good. For the most part, it's very easy to discover the entry points and get Copilot to do stuff. When its results are good, it's a very useful tool… but MS has some overall work to do to get consistency on that point.
Out of those use cases, though, four of them are just using Copilot as a natural-language front end (e.g. re-theming in Power BI). I would expect that to work well and, frankly, don't think it's that interesting as a use case. Sort of like Copilot for Windows… why do I want a natural-language system to tell me where setting X lives?
