Meta’s Muse AI Agent Launches on Mac Amid Rapid Adoption and Safety Scrutiny
By Drooid · · How we work
Launch and Immediate Market Reception
- September 8, 2026 – Meta released Muse on iPhone, Android, the web, and inside WhatsApp.
- Within the first five days, the app recorded roughly 600,000 downloads, according to Sensor Tower data.
- Within a week, Muse topped the U.S. App Store’s free-apps chart, surpassing ChatGPT.
- By September 10, iOS installs exceeded 83,000, moving the app from No. 4 to No. 2 on the chart.
- The September 17 Mac version expanded Muse to macOS, allowing the agent to act on files, messages, calendar entries, and notes.
Features and Technical Architecture
- Muse can send email, book travel, fill out forms, negotiate purchases, and pay via Link by Stripe (including one-time-use cards).
- The service runs inside a Muse Secure VM, an isolated Linux virtual machine that houses the agent, a browser, and the user’s connected accounts.
- A separate Sentinel process monitors outbound actions; it prompts the user for approval before any internet request is executed.
- Users choose which apps and data sources (e.g., health, financial, location) Muse may access and can revoke permissions at any time.
- Pricing: free up to 100 million tokens per week; $20 – $100 per month for higher-tier usage.
Official Statements & Responses
- Mark Zuckerberg announced the Mac launch on X, stating, “The team is shipping fast.”
- Jimmy Raimo, spokesperson for Meta, explained that “Some of that friction is intentional.”
- Vishal Shah, Meta’s vice president of AI products, told Reuters that the original April launch was postponed to meet security standards, achieving the company’s “minimum bar” for release.
- Meta asserts that the agent never sees passwords directly; payment details are stored securely and used only through Stripe’s Link system.
- A future Muse Confidential VM is slated for later 2026, promising full-disk encryption with a key held solely by the user.
Criticism & Opposition
- Privacy analysts note that the App Store disclosure lists health, financial, location, contacts, and browsing history as data categories Muse may collect, though Apple has not verified these claims.
- Users reported functional gaps: an Instagram workout video could be summarized only from the first frame; tasks requiring login via Google (e.g., ParentSquare) or WhatsApp groups (e.g., Girl Scouts) failed without manual intervention.
- Internal staff flagged a guard-rail breach during early testing that exposed a user’s private iCloud photos, highlighting ongoing safety concerns.
Data & Statistics
- 600,000 total downloads in five days (Sensor Tower).
- Muse achieved #1 on the U.S. free-apps chart, overtaking ChatGPT.
- JPMorgan upgraded META stock to Overweight, raising the price target to $820 following the launch.
- META shares rose ~0.6% to $657.65 on September 10.
Conflicting Reports & Gaps
- Download figures differ: 83,000 iOS installs reported by September 10 versus the broader 600,000 total across platforms in the first five days; the precise distribution remains unclear.
- Android adoption appears limited, with Muse listed at #338 in Google Play’s Productivity category, but no usage metrics are provided.
- Long-term user retention and willingness to pay beyond the free token limit have not been quantified.
What’s Next
- Release of the Muse Confidential VM later in 2026 to encrypt all user data and conversations.
- Integration of additional payment options such as Shop Pay.
- Ongoing monitoring of privacy and safety performance as the Mac version reaches a broader audience.
