OpenBrowserAgent

OpenBrowserAgent is an installed browser extension for Chrome, Firefox and Safari that combines page-focused chat with browser automation. It connects to local Ollama endpoints or model APIs you configure. Requests send selected browser context and messages to that endpoint; a remote model connection sends that material outside the browser.

Ask mode can answer questions about a page, compare tabs and summarize their contents. Chat context can include page text, tab metadata, selected elements and attachments. Responses can cite pages, files and external tool results so readers can check the material behind an answer.

Agent mode can inspect pages, click controls, fill forms, organize tabs and download content. The side panel displays tool activity during a task, with detailed tool output available for inspection. Chat supports streaming responses and queued messages.

Custom agents and reusable skills support recurring workflows. Skill packages can be imported and exported, and the extension accepts provider addresses for chat and image models.

Remote MCP servers add external tools such as web search and page fetching. These connections reach services outside the browser. The extension requires a successful connection test before enabling an MCP server and lets you control which individual tools the assistant can use. OpenBrowserAgent is open source under AGPL-3.0.

Provider configurations sync through browser sync by default, including API keys. Chats, attachments and agent workspaces stay local unless you enable their sync options.
