Meta's Muse is a personal agent that keeps working after you close the app. I finally have access, and I am putting it on my real workload. What Meta says it does. It remembers details you mention once. It works in its own cloud machine with a browser and files, keeps going in the background, and comes back when something changes. It asks before it sends an email or makes a purchase. You choose which apps it connects to, and for email you can allow reading only. It can also write its own connections to services that have an API. How I plan to use it: Track my campaign deadlines and remind me before each one. Fact check a draft against its source before I post it. Watch a few token launches and tell me what changed overnight. Turn a messy research pile into a short brief. Meta also says it can make mistakes, so I will check everything it does. I will share what it gets right, what it gets wrong, and what I stop doing by hand. Follow along and watch.
