Muse is Meta's personal AI agent, launched in the U.S. on September 8, 2026 on iOS, Android and the web at muse.ai, with the option to message it through WhatsApp. Unlike a chatbot, it is designed to act: it can open a browser, fill out forms and complete errands such as booking travel, buying tickets, scheduling lessons or sending email, and can turn a broad goal into a step-by-step plan. It is powered by Meta's proprietary Muse Spark model.
Meta's main answer to trust concerns is the Muse Secure VM, a dedicated virtual machine in which the agent and the user's data live, isolated from the rest of Meta's systems and watched by a separate security agent. Meta says Muse cannot see passwords or payment methods and that conversations are not shared with ad systems; those claims come from Meta and have not been independently audited. Pricing, as reported by TechCrunch, is a free tier plus Power at $20 per month and Maximum at $100 per month.
Note that "Muse" also names a wider model family: Muse Glimmer is a 30B-parameter open-weight model under Apache 2.0, distilled from Muse Spark to run agent loops on a single consumer GPU, and Meta has also released a Muse Code terminal coding agent. This entry reviews the consumer Muse agent. Its weak points are age and trust: it is weeks old, task reliability is unproven outside Meta's demonstrations, and the value of the agent depends on connecting sensitive accounts to a company with a contested privacy history. Compare with ChatGPT, Gemini and Manus.
