What this means for you

Nothing to migrate to yet — no price, no limits, no published evaluation. If you are assessing it, the question is the boundary: Gruber, quoted by Willison, says each user gets a full Linux VM in Meta's cloud, and the Mac build reaches local files, Mail, Messages and Notes.

Meta released Muse, a personal AI agent, on 8 September, on phones, the web and WhatsApp. A Mac version followed on 19 September that works with local files and native apps including Mail, Messages, Calendar and Notes. John Gruber, quoted by Simon Willison, says each user gets their own persistent Linux virtual machine in Meta's cloud (a separate software-defined computer of its own), calls Muse the first consumer-accessible agentic AI system, and doubts buyers grasp how much it can do. Meta has published no price, limits or underlying model in the coverage available.
