Page Agent is an open-source browser-side framework that gives a web page its own AI agent by adding a script to the application. The agent can understand and operate the page's graphical interface, allowing users to interact with existing web functionality through natural-language requests.

Because the agent lives with the page, developers can add AI-driven interaction without rebuilding every application feature as a separate API or tool integration. The project targets GUI understanding and action inside websites and can be used directly in applications or through its browser-extension ecosystem for experimentation.

Page Agent is useful for product teams that want to make existing interfaces agent-accessible, automate repetitive web tasks, or prototype natural-language control over a web application. It represents an alternative to external browser automation by embedding the agent capability closer to the page the user is already operating.
