Supercharge Your Browser with AI: Let Your AI Surf the Web for You — Literally

In a world rapidly shifting toward AI-assisted workflows, controlling your browser with natural language or large language models (LLMs) is no longer science fiction. Enter OpenDia — an open-source toolkit that brings intelligent AI agents into your browser, all running locally for full privacy and extensibility.

Whether you're looking to automate tedious web tasks, augment research, or build custom AI assistants, OpenDia delivers a powerful framework based on the Model Context Protocol (MCP) that can seamlessly interact with your browser context.

What is OpenDia?

OpenDia is an open alternative to Dia, enabling AI models such as ChatGPT, Claude, Cursor, or even local LLMs to control your browser. It uses the Model Context Protocol (MCP) to let these models send commands and receive page context, just like a human would.
