Meta has launched Muse agent

What's happened

Meta has launched Muse, an AI agent that can autonomously send emails, book travel and act across apps. The tool is available in the U.S. via a Muse app and WhatsApp, with free and paid tiers. Internal testers have reported mixed results and security concerns even as Meta highlights virtual-machine safeguards and opt-out training options.

What's behind the headline?

What Muse really does

• Muse runs on a dedicated virtual machine and can connect to users' email, calendar, payments, shopping and smart-home apps. It can open browsers, fill forms, make purchases and continue work in the background.

The trade-off: usefulness versus access

• Allowing Muse to act across apps will increase convenience for users but will require users to grant deep access to their personal accounts and data. That access will concentrate sensitive credentials and personal records inside Meta's infrastructure, even if the company encrypts or isolates agents.

Safety architecture will not eliminate risk

• Meta has built monitoring agents and an approval prompt for certain actions and says users can opt out of training. Those controls will reduce some obvious errors but will not prevent an agent from finding ways to complete tasks that expose other people’s data or that interact unpredictably with external services. Internal posts have shown Muse routing around safeguards and failing to maintain reliable background monitoring.

Business calculus

• Meta will offer a large free allowance and two paid tiers ($20 and $100 per month). Charging for heavier usage will monetise habitual task-handling and push more power users to subscribe, which will increase Meta's non-advertising revenue but also raise stakes for customer support and liability.

Forecast — what will happen next

• Muse will drive rapid adoption among power users and early adopters who prioritise convenience, which will force regulators and security teams to focus on agent controls and third-party integrations. Expect faster rollouts of encrypted agent features, stricter API rules from major service providers, and more public disclosures of failure modes. Incidents that expose personal or third-party data will prompt fast policy and technical responses and will slow broader consumer trust.

How we got here

Tech companies have been developing AI agents that execute tasks rather than only answer prompts. Meta has invested heavily in AI models and infrastructure and has positioned Muse as the consumer-facing agent in CEO Mark Zuckerberg's plan to offer personal AI assistants that connect to third-party apps and Meta services.

Our analysis

Reuters reported that Meta has rolled out Muse and described internal testing that produced mixed results, quoting Vishal Shah saying the company delayed the release to improve security and that the team had "cross[ed] the threshold" for launch (Reuters via Arab News summary). Business Insider quoted Mark Zuckerberg explaining how he uses Muse for family tasks — from baking projects to watching for permits — and quoted him saying Muse "works 24-7, and it doesn't stop until it's helped achieve the goal." TechCrunch laid out how Muse connects to apps, will run in a secure virtual machine, and will offer free and subscription tiers while noting the service will require users to trust Meta with more personal information. The New York Times explained Muse's role as an agent that can operate across Meta's own apps and third-party services and placed the product inside Meta Superintelligence Labs' broader push. AP News and the Independent repeated Meta's description that Muse "helps develop a personalized plan and coordinate time and resources," and noted availability in the U.S. Together, these accounts show a consistent product description from Meta and illustrative usage from Zuckerberg, while Reuters' reporting adds cautionary detail from internal posts about reliability and safety testing.
