What Is Meta Muse?

Meta Muse is Meta's personal AI agent. It runs in its own cloud VM, browses, uses your connected apps, and keeps working in the background. Free tier, $20 and $100 plans.

Meta Muse is Meta's personal AI agent, launched on September 8, 2026. You message it like a person, in the Muse app or in WhatsApp, and it acts for you: it browses the web in its own browser, fills out forms, reads and sends email through apps you connect, makes purchases, and keeps working after you close the app. It runs on Muse Spark, Meta's own model.

The difference from a normal chatbot is where it runs and what it can touch. Each user gets a dedicated Linux virtual machine in Meta's cloud, called Muse Secure VM, with a browser, a file system, memory, and stored logins for the services you connect. Muse can plan multi-step work, schedule tasks, and come back when it needs your approval, for example before sending an email or making a purchase.

Who can get it: Meta launched Muse in the US on iOS, Android, and muse.ai. Meta now also lists a Mac app. Meta says Muse isn't available everywhere yet, and you need to be 18 or older to subscribe.

What it costs: Muse is free with a usage limit that Meta doesn't quantify. Paid plans are Power at $20/month (500M "Muse tokens" per week) and Maximum at $100/month (3B per week), per Meta's Help Center as of September 26, 2026.

The tradeoff: Muse is only useful if you give it access to things like your inbox, calendar, accounts, and a payment method. Meta has published an unusually detailed security design for that. Two weeks in, a researcher had already disclosed a hijacking flaw in the Mac app, and Meta hot-fixed it. Model training on your Muse interactions is on by default.

Muse and Muse Spark

Muse is the agent product. Muse Spark is the model underneath it. Meta introduced Muse Spark on April 8, 2026, as the first model from Meta Superintelligence Labs. Meta's Muse security write-up names Muse Spark 1.3 as the model version at launch and says the model was trained for tool calling, long context, long task trajectories, prompt-injection awareness, and multi-agent coordination.

This matters for one reason. If you want Muse Spark in your own software, you don't use Muse. You call the model through Meta Model API (see "Not the same thing" below).

What Muse can do

Meta also says Muse remembers what you tell it and makes suggestions without being asked. Unlike most chat apps, it isn't turn-by-turn, so you can send follow-ups before it finishes replying.

Browser and app actions

Muse has a full browser inside its VM, and you share it. Meta's Help Center lists booking appointments, making purchases, filling out forms, and watching for price drops as typical browser tasks. You can open the browser to watch, take control to pause the agent, or stop the task. Muse may accept essential cookies on third-party sites. You can ask it which URLs it visited and which cookies it accepted.

For payments, Muse checks out with Stripe's Link, which generates a one-time card number so neither the merchant nor the agent sees your real card. Meta says eligible purchases get Link's purchase protections. At Connect on September 23, Meta added Shop Pay and PayPal as payment options.

Background execution

Muse keeps working after you close the app. Meta's example is monitoring daily weather reports and alerting you when rain is coming. Meta's engineering post describes subagents and cron-style scheduled tasks running inside the VM. You can see scheduled work under Upcoming and a chronological record under Activity log.

Approval model

This is the part to understand before connecting anything.

Meta's engineering post says approvals are enforced by a separate process called Sentinel, not by the agent. Sentinel is the only component that can approve connector actions and outbound network requests, and the approval dialog appears directly in the app rather than in your chat with Muse. That design means a manipulated agent can't just decide it has permission.

Meta is also plain about the limits. Its Help Center says Muse "can make mistakes or take unexpected actions," that you're responsible for fixing errors with third parties, and that some actions, like sending an email, can't be undone.

If you build agents yourself, Sentinel is Meta's version of a common pattern: keep the permission checks outside the model.

Connectors

Connectors are Muse's integrations with outside services. You add them in Settings → Connectors or by asking ("Connect my Gmail").

  • At launch: Meta says there were dozens of partner connectors plus access to the full Shopify catalog. Meta's own pages mention email, calendar, Instagram, and, on Mac, Messages, Calendar, and Notes.
  • Added at Connect (September 23): Walmart, Best Buy, American Eagle Outfitters, DICK'S Sporting Goods, Fanatics, Gap, Michael Kors, Sephora, Ulta, Wayfair, Instacart, Notion, Granola, GitHub, and Box. Expedia is listed as coming soon.
  • Meta's own apps: Facebook, Instagram, and Threads connect automatically if those accounts are in the same Meta Accounts Center as your Muse login.
  • Custom connectors: Muse can create a connector for an unsupported service, often from that service's API details. Meta says it doesn't review custom connectors or how they use your data.

Where a service supports it, Meta separates read access from write access. Many connectors can be limited to reading data without taking actions. Meta says an email connector lets Muse search your mail without downloading the whole inbox unless you ask it to. Meta's engineering post says the email connector filters out one-time codes, password-reset links, and magic login links.

Privacy and security tradeoffs

What Meta says it protects

What you're giving up

  • Training is on by default. Meta uses your Muse interactions to train its AI models unless you turn it off under Settings → Data controls. Meta says turning it off also applies to past interactions, and that it removes some personal identifiers before training.
  • Meta can currently access your VM. Meta says Muse Confidential VM, which is encrypted with a key only you hold, is planned for "later this year." Until then, Meta isn't claiming that Meta itself can't access your data.
  • Deleting isn't the same as forgetting. Meta says Muse may still remember what it learned from something you deleted. The forget skill removes things "to the best of its ability."
  • Your Meta accounts are connected by default. Facebook, Instagram, and Threads connect automatically through Accounts Center.
  • Muse sends data to third parties. Each connector has its own terms and privacy policy, and custom connectors aren't reviewed by Meta.
  • Prompt injection is still unsolved. Meta's engineering post says Muse isn't immune and calls prompt injection an open problem across the industry.

How it has performed so far

We don't have first-party results. Early outside hands-on coverage is mixed and specific to tasks.

Muse vs ChatGPT's agent

The comparison most people want is ChatGPT agent. OpenAI's Help Center now says ChatGPT agent "is no longer available" and sends users to ChatGPT Work for long multi-step tasks and to a cloud browser for browser workflows.
