BrowserOS is an open-source web browser that is agent-enabled and built on a fork of Chromium, integrating AI agents seamlessly into the online experience to facilitate task automation, navigation, and interaction with web applications using natural language commands. Users can log into websites as they normally would, and by issuing simple instructions such as “extract the quarterly results from this webpage and update a spreadsheet,” BrowserOS creates and executes a local, repeatable agent that takes care of clicks, form submissions, and other navigational tasks on their behalf. It comes equipped with a split-view feature that provides access to prominent large language models like ChatGPT, Claude, or Gemini, while also allowing for local model execution through platforms such as Ollama, ensuring it works harmoniously with existing Chrome extensions, bookmarks, and passwords. The browser enhances productivity by offering semantic search capabilities for browsing history and bookmarks, highlighting tools, and the option to set up MCP (Model-Context-Protocol) servers specifically for applications like Gmail, Calendar, Docs, and Notion, transforming it into a comprehensive productivity tool. Additionally, its user-friendly interface encourages a smooth transition for those accustomed to traditional browsing, as it simplifies complex tasks with the power of AI-driven automation.
