Microsoft showed off a slew of new devices and features at this week’s Surface event. We saw updates on the Surface Laptop Go 3, Surface Laptop Studio 2, and — the star of the show —  Microsoft’s Copilot AI assistant, which makes its full debut on Windows 11 on September 26.

But Copilot won’t be limited to the confines of Windows 11. The company revealed its Microsoft Edge and Bing chat-powered AI assistant will be able to communicate across all of Microsoft’s applications, tapping into your files, Microsoft 365 activity and your phone’s text conversations. In short, Microsoft wants Copilot to be at the heart of your Windows experience.

At the Surface event, Microsoft showcased some of its functionality. In a demo, Copilot, manifested as a chatbot embedded in the OS, was asked to check a Windows-11-connected phone for a user’s flight info. Copilot dug out the details in seconds, no scrolling through text conversations or email inboxes needed.

The assistant can also text people on your behalf. For example, if you’re trying to set up a little movie date night, you can ask Copilot to send your significant other all the upcoming showtimes. Or if get a text from a friend saying they’re visiting the city and have some free time, Copilot can suggest relevant places or events to see at certain times all without you having to do anything. Obviously, this all raises some privacy concerns. Microsoft has said users can toggle whether Copilot can access their texts.
