Meta’s Muse AI Agent Triggers Market Shake-up and Privacy Debate

Meta released its personal AI assistant, Muse, on September 8 as a scheduled rollout. The agent operates through a cloud-based virtual computer that can browse the web, send emails, book travel, and generate documents. Early adopters reported that Muse organized packing schedules, drafted restaurant recommendations into Google Docs, and attempted price negotiations on platforms such as Facebook Marketplace. The app’s interface features a Pixar-style avatar and five tabs for chat, interests, prompt ideas, goal tracking, and file management.

Within two weeks of launch, Muse climbed to the top of the free-app charts on both Apple’s App Store and Google Play in the United States and Canada. Sensor Tower recorded 2.5 million downloads initially and later 2.8 million with an average daily growth of 55 % in the first ten days. The rapid adoption coincided with a sell-off in sectors that rely on “consumer inertia.”
