Meta's new agent Muse is built to handle tasks on its own, from booking travel to shopping. It runs on its own virtual machine and you control it through WhatsApp.

Users can hand Muse simple jobs like sending an email or booking a trip, but Meta also claims it can take on bigger goals. For those, Meta says Muse plans the steps and coordinates time and resources. The agent opens a browser, fills out forms, and negotiates on the user's behalf. According to Meta, Muse can sell a car for more, lower a bill, or adjust a workout plan.

For longer tasks, Muse is supposed to keep running even when the app is closed. Meta says it checks in when something changes or when it needs approval, like before it actually sends an email or makes a purchase.

Muse also remembers what matters to users and makes suggestions on its own, according to Meta. The assistant taps into Meta's ecosystem here. Meta says it can turn a recipe reel saved on Instagram into a shopping list, or suggest a menu for a dinner party while accounting for friends' food allergies.
