Meta Launches Muse AI Assistant on Mac With Native Task Execution

Meta has launched its new AI assistant app, Muse, on macOS, expanding the tool to desktop environments following its debut on mobile and the web earlier this month. On Mac, Muse can natively interact with local files, messages, calendar entries, notes, and mail applications to execute tasks directly on the user's computer. Meta emphasized that access across these components is opt-in, and the agent requires clear approval from the user before undertaking any sensitive actions. The desktop release comes amid intensifying competition across the tech sector to build consumer-facing agentic AI systems capable of handling multi-step workflows. Market pressure has pushed platforms to accelerate their feature roadmaps; both Muse and competing agent Instinct introduced voice calling capabilities this week. The launch also reflects broader momentum in the agentic AI market, where early pioneers like Poke were acquired earlier this year and contenders like Instinct are reportedly seeking capital at valuations approaching $10 billion. Meta CEO Mark Zuckerberg highlighted the speed of the desktop deployment, noting that the team is focused on rapid delivery.
