What this means for you

Nothing to build on yet — Muse is a consumer product on Meta's own cloud, with no API, price or model details in the coverage. The part to watch is scope: the Mac version works across local mail, messages and calendar, so it reads as much as it writes.

Meta debuted Muse on 8 September 2026, a personal agent that MarkTechPost reports runs on its own dedicated secure cloud computer, putting it on phones, the web and WhatsApp. On 19 September it added Muse for Mac, the first version that completes tasks on a user's own machine, working with local files and native apps including Mail, Messages, Calendar and Notes. None of the coverage gives a price, model details or benchmark results, and TechCrunch and Wired both frame the launch around whether users will trust it.
