OpenMuse is a personal-agent application built with CopilotKit and AG-UI that combines a persistent Chromium browser, an optional Linux terminal, and file management into a single self-hosted platform. Users can assign open-ended tasks and follow along as the agent browses pages, runs commands, processes PDFs, and manages email and calendar via Google OAuth. The application runs on iOS, Android, and web using React Native and streams live task progress with support for pause, resume, cancel, and human review steps. OpenMuse is MIT-licensed, self-hostable, and designed as a starting template for developers building on top of CopilotKit infrastructure.
