Meta Muse hits 5M downloads in 22 days: the 6 concepts you need to use it
aakashgupta · x · 2026-10-18
Aakash Gupta breaks Meta's personal agent Muse into 6 core concepts: SOUL.md (editable rules file), Goals (tasks tracked instead of chat scrolling), Chief of Staff (a prompt that asks you 20 questions and saves answers to memory), Approval cards (mandatory yes/no before spending via Stripe Link), Library (finished PDFs/checklists/web pages), and Connections (start with just Gmail and calendar).
Recommended 10-minute setup: connect Gmail + calendar, enable Chief of Staff, write SOUL.md rules, turn off training in Settings, then give it one errand that can't spend money.
Per Apptopia, over 95% of Muse users are also on Facebook; Muse hit 5M downloads in 22 days vs 56 for ChatGPT, bringing agent newcomers en masse.
