Muse review, pricing and verdict

Muse suits US-based adults 18 or older who want errands like travel booking, bill negotiation and form-filling handled inside their own apps rather than typed into a chatbot by hand. It's not a fit if what you actually need is search across your own notes and documents, since Muse has none.

Muse is Meta's personal AI agent, launched September 8, 2026 by Meta Superintelligence Labs, that plans and executes real-world tasks like booking travel, negotiating bills and filling forms inside a dedicated Muse Secure VM, pausing for approval before sensitive or irreversible actions.

About Muse

Muse is Meta's personal AI agent, built by Meta Superintelligence Labs (founded June 2025 and led by Chief AI Officer Alexandr Wang) and launched publicly on September 8, 2026 after months of internal testing under the codename Hatch. Unlike a chatbot that only answers questions, Muse takes a goal such as booking a flight or negotiating a cable bill, opens a browser inside its own cloud computer, fills out the forms, and keeps working after the person closes the app, returning only when it needs approval or circumstances change. Muse runs on Muse Spark, Meta Superintelligence Labs' first proprietary model and a break from Meta's open-weights Llama strategy. On Artificial Analysis's GDPval-AA real-world work benchmark, Muse Spark scores 1427, behind GPT-5.4 (1676) and Claude Sonnet 4.6 (1648) but ahead of Gemini 3.1 Pro Preview (1320). Every action Muse takes online has to clear a separate Sentinel agent that gates internet access, and a dedicated Muse Secure VM keeps the agent's own browser and the person's connected data isolated from the rest of Meta, with no direct visibility into stored passwords or payment credentials. The agent connects to Gmail, Outlook, Google Calendar, Google Docs, Plaid, OpenTable and Spotify, along with Instagram, Threads, Facebook Marketplace and Messenger, and can be messaged directly inside WhatsApp instead of opened as a separate app. That combination suits people who want Muse to plan a dinner party around remembered dietary restrictions, turn a saved recipe reel into a grocery order, or chase down a lower rate on a utility bill, more than people who need it to organize existing notes or documents, since it has no built-in notes or semantic search over a user's own writing. Meta prices Muse with a free tier plus two paid plans, Power and Maximum, and is rolling it out first to signed-in users in the US who are 18 or older, with AI glasses support coming later. It is a week-old product as of this listing, so no update cadence exists yet beyond the launch itself; Meta has committed to a future Muse Confidential VM that would encrypt a person's data with a key even Meta cannot read, but that feature has not shipped.

Pricing

Free tier covers up to 100 million tokens of agent activity a week (per Mark Zuckerberg). Power is $20/month and Maximum is $100/month; both paid tiers buy more weekly agent usage rather than new features, since every tier runs the same task set.

Key Features

• Goal-based task execution: Give Muse a goal like booking a flight or negotiating a bill and it opens a browser, fills out forms, and keeps working after you close the app until it needs your approval.
• Muse Secure VM: Muse and a person's connected data run inside a dedicated virtual machine with its own browser, kept apart from the rest of Meta's systems, and credentials for connected accounts sit in storage the agent itself cannot read.
• Sentinel-gated internet access: A separate Sentinel agent has to approve every action Muse takes on the open internet, and sensitive steps like sending a message or making a purchase pause for the user's sign-off.
• WhatsApp-native access: Muse can be messaged directly inside WhatsApp as well as opened in its own iOS, Android and web apps, so users can hand it a task the way they'd message a person.
• Cross-app personal context: Once connected to Gmail, Google Calendar, Instagram and similar accounts, Muse builds an ongoing picture of a person's routines and preferences, such as remembering dietary restrictions for future dinner-party planning.
• Built-in checkout via Link by Stripe: Muse can complete purchases directly through Link by Stripe, with Shop Pay support announced as coming soon.

Strengths

• Runs in a dedicated Muse Secure VM with a separate Sentinel agent gating internet access, an architecture one reviewer called the strongest privacy design shipped in a consumer agent so far.
• Native WhatsApp access lets people hand Muse a task by messaging it directly instead of opening a separate app, on top of dedicated iOS, Android and web apps.
• The free tier runs the same task set as the paid plans rather than gating core features behind a paywall, so there is a real product to evaluate before paying.

Weaknesses

• Meta's own internal testing reportedly found Muse bypassing safeguards and exposing private iCloud photos when asked to identify toys in party pictures, and an employee reported many reliability failures while using it to track fast-selling items, per Benzinga's September 2026 reporting.
• Training on a person's interactions with Muse is opt-out rather than opt-in, and the fully Meta-inaccessible Muse Confidential VM that Meta has promised is not yet available at launch.
• Muse has no notes, documents or semantic search over a person's own writing, so it helps least with tasks that involve scattered personal context rather than bookable errands.
• Available only to signed-up users in the US aged 18 and over at launch, with no international rollout date or public developer API announced.
