Meta is expanding its Muse AI assistant to desktop computers with the launch of a dedicated Mac application. The move gives users another way to access the AI assistant and brings it closer to the software and files they use every day.
Muse first arrived on mobile devices and the web in September 2026, quickly attracting attention and climbing to the top of the U.S. App Store rankings. Meta is now taking that momentum to the desktop as it looks to make Muse a more useful part of users’ everyday digital routines.
Meta executives Alexandr Wang and CEO Mark Zuckerberg announced the expansion on X. Zuckerberg highlighted the speed of the rollout, saying the team is “shipping fast.”
The Mac version is designed to do more than simply provide another window for chatting with an AI. Meta is positioning Muse as a desktop assistant that can interact with information and applications already stored or used on a Mac.
Instead of requiring users to copy and paste information into a chatbot, the desktop assistant is designed to work with files, messages, calendars, notes and email. This could allow users to ask Muse to help find information, organize tasks or work with content across different parts of their computer.
The integration is part of a broader shift in how AI assistants are being developed. Traditional chatbots largely wait for users to provide information before generating an answer. AI agents, by comparison, are increasingly being designed to interact with software and complete tasks using information already available on a device.
Meta is also giving users control over what Muse can access. The company has built permission controls into the Mac application so users can decide which parts of their computer the assistant is allowed to interact with.
Access to files and other sensitive information is not automatically granted. Instead, the system operates on an opt-in basis, meaning users must give Muse permission before it can perform certain actions or access protected information.
The permission system is particularly important because a desktop AI assistant can potentially interact with much more personal information than a standard chatbot. A computer may contain private documents, emails, photographs, financial records, work files and other sensitive data, making user control a key part of the experience.
Muse can also be kept within easy reach by placing it directly in the Mac dock. That allows users to open the assistant alongside the other applications they regularly use rather than treating it as a separate service that they have to access through a browser.
The Mac launch comes as competition around AI assistants becomes increasingly focused on agents that can actually perform tasks. Companies across the technology industry are developing systems that can move beyond answering questions and instead interact with applications, files and digital services on behalf of users.
For Meta, bringing Muse to the desktop gives the company an opportunity to make the assistant part of everyday computer use. The company already has a large ecosystem of applications and services, including Facebook, Instagram and WhatsApp, which could provide additional opportunities for Muse to connect with users' existing digital lives.
The move also reflects a broader change in the relationship between people and computers. Instead of users having to open individual applications and manually complete every step of a task, AI agents are increasingly being designed to understand what a user wants and then interact with the necessary software to help accomplish it.
That could eventually change how people use computers, with AI assistants becoming a layer between users and the applications they rely on. Rather than simply recommending what to do, these systems are being developed to take action, subject to the permissions granted by the user.
Muse’s arrival on Mac therefore represents more than an expansion to another platform. It gives Meta’s AI assistant access to a computing environment where users carry out work, manage information and store important files every day.
As Meta continues developing Muse, the company will be competing in a rapidly expanding AI-agent market where the focus is shifting from conversational assistants toward systems capable of interacting with the digital tools people already use. The Mac application gives Muse a new place in that competition and could become an important step in Meta’s broader AI strategy.
