Meta’s Muse Tops US App Store, Expands to Mac
Meta’s Muse is positioned as a personal AI agent that goes beyond generating conversational answers. The app is designed to understand instructions and take actions across platforms on a user’s behalf, including carrying out complex, multi-step tasks. Its rapid adoption underscores growing consumer interest in agentic AI products that can complete work rather than simply provide information, opening a new front in competition among major technology companies.
Muse reached No. 1 on Apple’s US App Store free-app chart just 10 days after launch, briefly moving ahead of OpenAI’s ChatGPT. Meta has since brought Muse to Mac, extending the agent’s ability to act directly on a user’s computer. The desktop expansion broadens its potential use cases and builds on the early chart success, offering fresh evidence of strong demand for task-oriented AI agents.

The history behind this eventMeta Launches Muse to Close Gap in AI Agent Race
AI agents go beyond answering questions by acting across services, turning them into the next battleground in consumer AI. Meta is positioning Muse at the center of CEO Mark Zuckerberg’s “personal superintelligence” strategy as it seeks to narrow the gap with OpenAI and Google and diversify beyond advertising. The launch also gives investors a tangible product against more than $130 billion of planned 2026 spending on AI chips and infrastructure.
Meta launched Muse in the United States on Sept. 8, 2026, through iOS, Android, muse.ai and WhatsApp, with a free tier plus $20 and $100 monthly plans. The agent can keep working on email, shopping and travel in a dedicated Muse Secure VM, pausing for approval on sensitive actions. Sensor Tower estimated more than 83,000 U.S. iOS downloads, and Muse reached No. 2 on Apple’s U.S. App Store on Sept. 10. Meta shares surged 6.55% on Sept. 9 to close at $653.69.
Meta Launches Muse Code to Challenge OpenAI, Anthropic
Meta Platforms is expanding its generative-AI push into software development, taking aim at terminal-based coding tools led by Anthropic’s Claude Code and OpenAI Codex. Meta Superintelligence Labs introduced the Muse Spark model family on April 8 and opened a paid developer API on July 9. Muse Code marks a broader effort to turn Meta’s AI research into commercial tools for engineers handling complex, repository-scale work.
Meta AI released Muse Code in beta on Aug. 5, powered by the new Muse Spark 1.2 model and available on macOS and Linux. The agent can plan changes, write code, run tests and verify results, while persistent asynchronous background agents continue working across long sessions. Standard API pricing is $1.25 per million input tokens and $4.25 per million output tokens. Meta said one demonstration ran for up to 24 hours and made more than 1,000 tool calls.
