BrowserOS is an open-source AI browser with 6.5k+ GitHub stars. Run local AI agents, chat with ChatGPT, Claude, and Gemini in one place, and reclaim your privacy.
Racking up over 6.5k GitHub stars in a remarkably short time, this AI-driven open-source browser is redefining our web experience! Have you ever fantasized about a browser that truly understands your needs and proactively helps you complete tasks? BrowserOS is exactly such a revolutionary open-source project—it deeply integrates artificial intelligence into the browsing experience, running AI agents locally to protect your privacy while transforming the browser from a passive tool into an active assistant.
🔍 What is BrowserOS?
BrowserOS is an open-source AI agent browser built on Chromium. It deeply integrates AI capabilities into the browsing experience while adhering to a privacy-first design philosophy. Unlike traditional cloud-based AI browsers, BrowserOS lets users run AI agents on their local devices, giving you full control over your data with no privacy concerns.
The project was created by Nithin and Nikhil Sonti, engineers with backgrounds at Google and Microsoft, and is backed by Y Combinator. Released under the AGPL-3.0 license, BrowserOS is fully open-source on GitHub, offering a browsing experience that feels both familiar and innovative.
Put simply, BrowserOS is like installing a brain that thinks and acts into a traditional browser—it understands your commands and automatically handles complex web tasks for you.
⭐ Why BrowserOS is Worth Your Attention
In today's increasingly competitive AI browser landscape, BrowserOS stands out with a unique positioning:
- 🛡️ A privacy-first alternative to closed-source products like Perplexity Comet
- 💻 Local AI agent execution—your data never leaves your device
- 🔓 Fully open-source and transparent, unlike many closed commercial products
- 🔌 Compatible with Chrome extensions, so you don't have to abandon your existing browser ecosystem
The BrowserOS team believes: "Since Netscape in 1994, this is the first time we've felt we could reimagine the browser from scratch. We saw how Cursor gave developers 10x productivity, but the browser feels stuck in the past."
🌟 Core Feature Highlights
🤖 Intelligent AI Agent System
At the heart of BrowserOS is its powerful AI agent system, capable of translating your language into real actions. Simply describe the task you want completed in natural language, and BrowserOS converts it into a repeatable agent that runs locally.
Real-world usage examples:
- 📦 "Browse to Amazon and search for wireless earbuds"
- 📧 "Log into Gmail and check unread important emails"
- ⚖️ "Compare the prices and reviews of these three products"
- ✍️ "Fill out this form using my personal information"
🔄 Multi-AI Model Integration
BrowserOS lets you interact with multiple leading AI models simultaneously, eliminating the need to switch between tabs or websites. You can chat directly with ChatGPT, Claude, Gemini, Perplexity, and more within the side panel.
Even more powerful, the LLM Hub feature lets you compare responses from different AI models side by side—perfect for research, fact-checking, and bias identification.
🎛️ Three Smart Modes
BrowserOS offers three distinct smart modes to suit different scenarios:
- 💬 Chat Mode: The AI can observe your open tabs and summarize, translate, or extract information from them in real time
- ⚡ Agent Mode: It can click, scroll, and fill out forms for you—finding products, even adding them to your cart
- 👨🏫 Teach Mode: Show BrowserOS how to do something once, and it remembers your actions and repeats them in the future
🛡️ Privacy Protection & Local Processing
Unlike most browsers that collect user data, BrowserOS is committed to a privacy-first principle. You can run models locally via Ollama or plug in your own API keys. This means your work and personal data stays on your machine unless you explicitly choose to send it out.
🔗 MCP Server Support
BrowserOS comes pre-installed with MCP servers for Gmail, Calendar, Docs, Sheets, and Notion. You can install any other MCP server with a single click, turning the browser into the control center for all your work tools.

💡 Tips for Efficient Use
🎯 Mastering the Art of AI Prompts
To fully unlock BrowserOS's potential, learning to give effective instructions is essential:
- ✨ Be specific and clear: Don't just say "search for earbuds"—say "search for noise-cancelling wireless earbuds on Amazon and sort by rating"
- 🎯 Step-by-step instructions: Break complex tasks into multiple steps, e.g., "log into my email, find the latest bill, download the PDF, and save it to the Downloads folder"
- 🔍 Provide context: Make sure you've navigated to the relevant page before executing tasks, or include navigation steps directly in your prompt
🔄 Make the Most of Teach Mode
Teach Mode is one of BrowserOS's most powerful features. When you need to perform the same task regularly, simply demonstrate it once, and BrowserOS will remember your actions. For example:
- 📊 Monthly data extraction workflow for generating sales reports
- 💾 Regularly backing up information from specific websites
- 📝 Automating repetitive form filling
🎨 Create Personalized Agents
You can create custom agents tailored to your specific needs. BrowserOS provides an API for registering agents, letting you define specialized assistants for specific task types.
🗂️ Smart Tab Management
If you're the type who constantly has 70+ tabs open, BrowserOS's AI features can automatically organize, group, and summarize your open tabs, freeing you from tab chaos.
