BrowserOS: Free Open-Source AI Agent Browser That Runs Locally to Protect Privacy

Product Introduction

BrowserOS is a free, open-source AI Agent browser that integrates powerful AI agents directly into the browser, running entirely locally. It supports automated tasks (such as filling out forms and scheduling meetings) and deep research capabilities. BrowserOS places a strong emphasis on privacy, supports running local models (such as Ollama), and never uploads your data to the cloud. It also offers semantic search, local AI chat, and productivity tools, is compatible with all Chrome extensions, and features an interface similar to Google Chrome — so there is no learning curve to get started.

Key Features

• Automated tasks: With natural language instructions, AI agents can automatically complete tedious tasks, such as filling out forms, scheduling meetings, or reordering from past orders.
• Web operation: Agents can mimic human actions — browsing pages, clicking buttons, and completing tasks.
• Local execution: All AI operations run locally, so your data never leaves your device, ensuring privacy.
• Ollama integration: Supports running Ollama models locally, using your own API keys or local models.
• Semantic search: Search your browser history, bookmarks, and more semantically to quickly find relevant content.
• Tab management: AI helps you manage tabs, grouping and organizing them in one click to boost browsing efficiency.
• Built-in highlight and bookmark tools: Highlight web content and get smart bookmarking powered by ChatGPT.
• Local AI chat: Reference the currently open page directly in the chat box so the AI can answer page-related questions; multi-model comparison lets you run multiple models side by side in a single window and view their answers simultaneously.

5. Configure an AI provider: connect to OpenAI or Anthropic, or run Ollama locally.
6. Launch the browser and create AI agents with natural language instructions to automate tasks.
7. Explore local AI chat, one-click tab grouping, semantic search, and other features.

Core Advantages

• Privacy first: All AI operations run locally, with support for local Ollama models — sensitive data never leaves your machine.
• Free and open source: The source code is hosted on GitHub, free to use and audit.
• Zero learning curve: The interface resembles Google Chrome and supports all Chrome extensions, so Chrome users can switch seamlessly.
• Natural language driven: One sentence is all it takes for an agent to complete everyday tasks like filling forms or scheduling meetings.
• Flexible multi-model support: Connect to OpenAI or Anthropic APIs, or run fully locally — choose as you need.

Use Cases

• Automating repetitive tasks: Use AI agents to quickly schedule meetings, fill out forms, or handle other tedious daily chores.
• Deep research: Agents automatically browse the web, organize information, and generate reports to help you finish research efficiently.
• Content curation: Scan social media platforms such as LinkedIn and Twitter to filter out valuable content and save time.
• Local AI chat: Reference the current page in the chat box and get instant answers to page-related questions.
• Tab management and semantic search: Group tabs in one click and use semantic search to quickly find relevant history or bookmarks.

Project & Pricing

• Official website: https://www.browseros.com/
• GitHub repository: https://github.com/browseros-ai/BrowserOS (free and open source)
• Cost: BrowserOS itself is free to use. If you connect cloud models such as OpenAI or Anthropic, you pay the corresponding API fees; using local Ollama models incurs no such cost.
