Meta’s Muse AI Agent Is Coming to Windows PCs as a Native App

Meta’s Muse personal AI agent is coming to Windows PCs as a native app, Microsoft announced on stage at its Windows and Surface event in San Francisco on Wednesday, October 7, 2026, though neither company has given a release date.

Muse is Meta’s personal AI agent, designed to complete tasks like booking appointments, filling out forms and managing email rather than just answering questions. It launched in the U.S. on September 8, 2026, on iPhone, Android and the web, then arrived in Canada on September 18, 2026, where it quickly climbed to No. 1 on the App Store. Meta followed with a native iPad app today, leaving Windows as the biggest platform still waiting.

Pavan Davuluri, Microsoft’s executive vice president of Windows and Devices, made the announcement during the keynote. In a post on Microsoft’s Windows Experience Blog published after the event, he wrote that “Muse for Windows, a personal AI agent from Meta, is coming soon as a native app on Windows with MXC integration,” calling it a way of “providing more choice in the agents people can use on their Windows PC.”

The “MXC integration” Davuluri mentioned refers to Microsoft Execution Containers, a sandboxing layer that became generally available on Windows 11 today. It lets organizations decide which files and networks an AI agent can reach, with those rules enforced while the agent runs, and Microsoft says the same safeguards are built into the experience for people using agents on a personal PC.

OpenAI’s Codex, GitHub Copilot and OpenClaw already support MXC, according to Microsoft, while Anthropic’s Claude Code, Perplexity and Manus are among those planning to add it. Microsoft is pushing its own Copilot agent at the same time, which makes giving stage time to a rival agent from Meta a notable move.

A native app would bring Windows users closer to what Mac owners have had since Meta released Muse for Mac on September 17, 2026. That app can work with files, notes, calendars and email on the computer itself, asking permission before sensitive actions. It also needed a quick fix after a researcher disclosed a security flaw in the Mac app last month. Windows users have so far been limited to the web version at muse.ai, where the agent runs in Meta’s cloud-based Muse Secure VM and can’t reach files on the PC.

Neither Microsoft nor Meta has shared a launch date for the Windows app, and Meta has yet to post its own announcement. It also isn’t clear whether the app will need Windows 11 or a Copilot+ PC, whether it will come through the Microsoft Store or as a download from Meta, how much local file and app access it will get compared to the Mac version, or which countries will get it first.

Canada is one of only two countries where Muse is officially available, alongside the U.S., which puts Canadians in a good position when the Windows app ships, but Canadian availability hasn’t been confirmed yet. Muse is free for most tasks, with paid Power and Maximum plans at $20 and $100 per month for higher limits, and there’s no word on whether the Windows app will change that.
