Meta’s personal AI agent Muse tops US App Store

Meta’s personal AI agent Muse tops US App Store, reaching the No. 1 spot among free iPhone apps in the United States within a week of its launch. The milestone, confirmed by Meta’s Chief AI Officer Alexandr Wang on September 18, 2026, marks a significant early win for Meta’s push into personal superintelligence and puts Muse ahead of OpenAI’s ChatGPT on Apple’s free app chart.

Muse launched on September 8, 2026, as a dedicated app for iOS, Android, and the web, offering a free tier with up to 100 million tokens per week and paid “Power” and “Maximum” plans at $20 and $100 per month. The rapid climb to the top of the chart signals strong consumer interest in an AI agent that can act on behalf of users rather than just answer questions.

App Store performance and rankings

According to multiple app-tracking sources and Meta’s own announcement:

• Muse reached No. 2 on the US iOS App Store within two days of launch, with over 83,000 US iOS downloads in that period.
• By September 18, one week after launch, it had moved to No. 1 among free apps, displacing ChatGPT.
• Competing AI assistants such as Google Gemini, Anthropic’s Claude, xAI’s Grok, and Microsoft Copilot ranked well below Muse on the same chart.

Alexandr Wang posted on X: “A week after launch, Muse is now the No. 1 app in the App Store!” The ranking is based on download velocity and can shift as new apps launch or user interest changes, but it underscores Muse’s strong initial traction.

What Muse offers

Muse is positioned as a personal AI agent rather than a standard chatbot. It is designed to:

• Research topics and summarise information.
• Fill out forms and handle routine paperwork.
• Book restaurant reservations, travel, and appointments.
• Shop online and compare options.
• Find services such as dog sitters, tutors, or local providers.
• Connect with email, calendars, Spotify, Instagram, OpenTable, and other services.

The agent runs on Meta’s Muse Spark 1.3 model and is initially available only in the United States for users aged 18 and over. It is accessible via:

• A dedicated Muse app on iOS and Android.
• The web at muse.ai.
• Integration inside WhatsApp for conversational access.

Free tier and paid plans

Meta is using an aggressive freemium model to drive adoption:

• Free tier: Up to 100 million tokens per week, far higher than most competitors’ free allowances.
• Power plan: Reported at $20 per month for heavier usage.
• Maximum plan: Reported at $100 per month for advanced agentic workflows and higher compute.

Reports also indicate that a payment card is required on file even for the free tier, though users are not charged unless they exceed the free allowance or subscribe to a paid plan.

Personal AI agent race

Muse’s App Store success comes amid intensifying competition in the personal AI agent space:

• OpenAI’s ChatGPT and Atlas agents.
• Google’s Gemini and emerging agent features.
• Anthropic’s Claude with expanded tool use.
• Startups and niche agents focusing on specific tasks such as travel, finance, or productivity.

Early user anecdotes shared online describe Muse as an “ADHD lifesaver,” a tool that helped catch potential fraud that a bank missed, and a way to save thousands on car insurance by automating quotes and negotiations. While these stories are not independently verified, they illustrate the kind of high-impact use cases Meta is hoping to normalise.

Summary: Meta’s personal AI agent Muse tops US App Store, reaching No. 1 among free iPhone apps within a week of launch and surpassing ChatGPT. With a generous free tier, paid plans at $20 and $100, and capabilities spanning research, forms, bookings, and shopping, Muse marks a strong early win for Meta’s personal superintelligence strategy.
