nanoMuse offers an open-source personal agent running on all user devices
nanoMuse is an open-source personal agent that runs locally on a user's phone and computer, sharing a conversation across devices via an optional relay, with user-controlled memory and permissions, aiming to replicate and extend Meta's Muse agent in an open, inspectable form.
Based on the paper nanoMuse: An Open-Source Personal Agent for Every Device You Own by Guangyi Liu, Yong Liu, Jiangning Zhang
The evolution and challenge of personal agents
Personal agents are software programs that act on behalf of a single user, managing their accounts, devices, and files over extended periods, including while the user is away, and providing logs and permissions for accountability.
Historically, assistants like Siri or Alexa answered queries and waited, while recent agents perform tasks and stop. Meta's Muse (2026) introduced a persistent, cloud-based personal agent with memory, proactive messaging, and safety features, but it runs in a vendor-controlled cloud VM and is closed-source.
The challenge is to build a personal agent that is open, inspectable by the user, runs on their own devices, and can operate across multiple devices with shared memory and permissions, while maintaining safety and privacy.
