Muse is a personal AI agent developed by Meta Platforms, announced on 8 September 2026. Meta describes it as an agent that carries out long-running tasks on a user's behalf rather than answering single questions like a chatbot. It was part of a wave of consumer personal AI agents launched in 2026 alongside OpenAI's Dots, xAI's Grok Bot and the startup Instinct.
Capabilities
Muse can open a browser, fill out forms, send email, book and pay for things, and keep working after the user closes the app. Typical tasks include drafting and sending emails, booking travel, buying tickets, negotiating bills and building multi-week plans. It is designed for delegation of everyday chores rather than conversation.
Availability
Muse launched in the United States and is available to adults (18+) on iOS, Android, the web at muse.ai, and inside WhatsApp. It is free for most use, with reported paid tiers at $20 and $100 per month.
Security
Muse runs on a dedicated virtual machine Meta calls Muse Secure VM, which houses both the agent and the user's data. Meta said it would later introduce Muse Confidential VM, where the entire VM, including the user's data and conversations, is encrypted with a key only the user holds, so that not even Meta can access it.
Reception
Commentators framed Muse as a bet on whether consumers will trust an agent with payments and accounts, a recurring question across the 2026 personal-agent launches.
