According to Microsoft, you can safely send your work related stuff to Copilot. Besides, most companies already use a lot of their software and cloud services, so LLM queries don’t really add very much. If you happen to be working for one of those companies, MS probably already knows what you do for a living, hosts your meeting notes, knows your calendar etc.

If you’re working for Purism, RedHat or some other company like that, you might want to host your own LLM instead.
