Page Agent is an open-source in-page GUI agent — a single JavaScript library gives any web page its own AI agent, no extension or backend needed.

In-Page GUI Agent: A single JavaScript include gives any web page its own AI agent that lives inside the page, with no extension or backend required.
Text-Based DOM Manipulation: Operates on the DOM through text — no screenshots or multi-modal LLMs, so it's lightweight and privacy-friendlier.
Bring Your Own LLM: Works with most mainstream models and locally-deployed LLMs so teams stay in control of prompts and data.
Optional Chrome Extension: A companion Chrome extension lifts the agent out of a single page so it can drive multi-page tasks and cross-tab workflows.
MCP Server (Beta): An included Model Context Protocol server lets external agents connect and control Page Agent from outside the browser tab.
Ships as an npm Package: Distributed as `page-agent` under an MIT license with TypeScript typings and a small bundle size.

SaaS AI Copilot: Ship an in-product AI copilot in an existing SaaS web app without building a browser extension or backend agent.
Onboarding & Guided Tours: Have the agent walk new users through the UI step-by-step, interacting with the real DOM.
Web Automation: Automate repetitive DOM tasks (form fill, data extraction, batch updates) driven by natural-language instructions.
Multi-Page Workflows: Combine with the Chrome extension to drive workflows that span multiple tabs and origins.
Agent Orchestration via MCP: Let external agent frameworks control a live web page through the MCP server for testing or automation.
