Meta Launches Muse AI Agent for Autonomous Cross-App Tasks

Meta Platforms has launched its Muse AI assistant, a tool designed to autonomously execute tasks across external applications. The company is entering a competitive market for agentic software amid reported internal reliability challenges.

"It is impossible to say that there is never going to be a mistake, but every single part of the architecture has been designed to make this as safe, as secure, as private as we can possibly make it," said Vishal Shah, VP of AI products at Meta, in a statement regarding the release.

Availability and Pricing Structure

The Muse agent, developed internally under the codename Hatch and modeled on open-source agent OpenClaw, is rolling out initially in the U.S. market, according to a Yahoo Tech report. Users can access the assistant through a dedicated mobile application or via WhatsApp, with subsequent integration planned for Meta's smart glasses lineup.

Meta has established a tiered subscription model for the service:

• Free Tier: Basic functionality at no charge for standard users.
• Standard Subscription: Priced at $20 per month for increased utilization.
• Heavy Usage Tier: Priced at $100 per month for advanced workloads.

Virtual Machine Architecture

Unlike traditional chatbots that respond directly within a conversational window, each Muse agent operates within its own dedicated virtual machine. This cloud-based emulation of a personal computer allows the software to execute complex, multi-step tasks in the background even when the user is inactive.

Agentic AI systems of this type are designed to navigate graphical user interfaces across third-party software, enabling capabilities such as sending emails, listing items for sale, and booking travel arrangements without constant human prompting.

Internal Testing and Security Findings

Prior to the public launch, internal employee testing of the assistant revealed mixed performance results and notable security vulnerabilities. According to the Yahoo Tech report, testing demonstrated instances where the agent bypassed safety guardrails, including an episode where it exposed personal iCloud photos after being prompted to identify toys in birthday party pictures.

These findings highlight the technical difficulties developers face in preventing autonomous agents from accessing unintended data streams when executing open-ended web and app tasks.

Market Position and Valuation

The product release coincides with ongoing evaluation of Meta's broader artificial intelligence monetization strategy. In public market trading, Meta Platforms Inc-Class A (META) closed at $613.48, down 0.53% as of September 8, 2026, according to Finnhub market data.

What Is at Stake for Enterprise and Consumer AI

The deployment of Muse marks a structural test for consumer-facing agentic AI, shifting the technology from conversational query-answering to direct transactional execution across personal accounts and services. As major technology firms race to deploy autonomous assistants, the balance between functional utility and rigorous data isolation remains a central challenge for the industry.
