Pebs vs Muse
Pebs vs Muse: what's different?
Both are personal AI agents that can act on your behalf. Muse, from Meta, runs on a persistent Muse Secure VM with a full browser, ships as an app on mobile and Mac and inside WhatsApp, and is free with a usage limit. Pebs are character-based agents inside Nox powered by GHI-1, with a per-task Cloud Browser and secure cards for secrets, included with Nox MAX and NOX 50.

What Pebs is
Pebs is a personal AI agent by Nox. It works in its own Cloud Browser, runs several tasks at once, and handles long-running work. Miso and Orbit are the first two Pebs. Coming to Nox on all platforms November 1, 2026.
Pebs runs inside the Nox account on the web and is included with the Nox MAX and NOX 50 plans. Read more on What is Pebs and How Pebs works.
What Muse is
Meta describes Muse as "your personal AI agent" that gets to know you and your goals and works across all aspects of life. Muse can take actions and complete multi-step tasks on your behalf, and asks your permission before taking certain actions.
Muse Secure VM is described as a persistent, isolated Linux computer with a full browser that you and your agent can use to complete tasks, allowing you to intervene at any point. Muse is available in the Muse app on mobile and Mac, or directly in WhatsApp, and is free with a usage limit, with a paid subscription for more.

Main differences
- Computer model: Muse gives you a persistent VM that you and the agent share. Pebs opens an isolated browser per task and closes it when the task is done.
- Where it lives: Muse is its own app and runs in WhatsApp. Pebs lives inside Nox.
- Price model: Muse starts free with a usage limit. Pebs is included with the paid Nox MAX and NOX 50 plans.
- Character: Pebs is designed around Miso and Orbit. Meta's Muse page does not describe a character layer.
- Secrets: Pebs routes sign-ins, codes and card details through secure cards that bypass the model. Meta's page describes permissions and approvals in general terms.
Who each may be better for

- You want a designed character with readable states.
Muse may fit better if
- You want to start free.
- You live in WhatsApp or want a native mobile and Mac app.
- You want a persistent computer that keeps state between tasks.
