BrowserOS is an AI-native browser that lets you automate any web task by describing it in plain English. Built on Chromium, it runs AI agents locally on your machine—keeping your data private while giving you superpowers for browsing.
**Open source. Privacy-first. The browser for the AI era.**
## Three Ways to Use AI
Ask questions about the page you're viewing. Summarize articles, extract data, translate content—without leaving the page.
Describe a task and watch AI execute it: clicking, typing, navigating. Automate form filling, data extraction, and multi-step workflows.
Build reliable, repeatable workflows as visual graphs. Edit steps, save, and run anytime. *Coming soon.*
## Quick Start
Get the latest release from [browseros.com](https://browseros.com) for macOS, Windows, or Linux.
Navigate to `chrome://settings/importData` and import your bookmarks, passwords, and settings in one click.
BrowserOS includes a default AI model with limited daily usage for testing. For the full experience, bring your own API keys.
Configure Gemini, Claude, OpenAI, or run models locally with Ollama
Open any webpage and press the **Assistant** button in the toolbar. Ask a question about the page, or describe a task to automate.
## Which AI Model Should I Use?
**Any model works great**, including local LLMs.
- **Ollama** or **LM Studio** — Free, runs locally, great for quick questions
- **Gemini Flash** — Fast and affordable
- **Claude or GPT-4** — Best quality responses
Chat Mode just needs to understand the page and answer questions—local models handle this well.
**Use Claude Opus 4.5 for best results.**
| Model | Speed | Quality |
|-------|-------|---------|
| Claude Opus 4.5 | Slower | Best |
| Claude Sonnet 4.5 | Medium | Great |
| Claude Haiku 4.5 | Fast | Good |
| Gemini Flash | Fast | Good |
Local LLMs are not yet powerful enough for Agent Mode. The model needs strong reasoning to click the right elements and handle multi-step tasks.
