Giving an AI assistant access to your files is a bigger change than giving it another chat box. At its Windows and Surface event, Microsoft showed a Copilot upgrade designed to read local files and take actions across the operating system, under an approach it calls “Hybrid Intelligence.”
A mix of local and cloud AI
Microsoft described Hybrid Intelligence as a way for apps and tools to use a combination of local and cloud AI models to complete tasks. The company did not provide further details in the report about how the models divide the work or what controls govern access to files and Windows actions.
The shift is practical in intent: the assistant is being presented not only as a place to ask questions, but as a tool that can work with information on the PC and act within the OS. The demonstration offered a glimpse of that idea, not a full account of its limits.
A tax-filing demonstration
Jacob Andreou, Microsoft’s executive vice president of Copilot, showed a video in which he asked the company’s Autopilot tool for help filing taxes. He told the agent that he had received an email from his accountant and asked it to get her something. The available description ends before saying what he wanted sent or whether the task was completed.
That leaves the central product details unanswered. The demonstration showed the direction Microsoft is taking, but the report does not specify availability, permissions, or the safeguards around access to personal files. An assistant that can act on your PC may save a few steps. The important question is which steps it is allowed to take.
