Overview

BrowserOS is a free, open-source web browser built on Chromium with an AI agent built into every new tab. You ask in plain words and the agent summarises pages, clicks through steps, pulls data from a page or runs a task on a schedule, using built-in tools and app integrations such as Gmail, Slack and Notion. You connect the AI provider you already use, or a local model through Ollama. It suits everyday browser users who want an assistant that works on the sites they visit.

It is an open-source alternative to closed AI browsers, and you choose the AI model, including a local one.

Good to know

You want an assistant inside the browser you use every day. BrowserOS puts an agent in each new tab that can summarise the page, click through a flow, pull data out or run a task on a schedule, with the AI provider you connect.

Limits

You connect your own AI provider; a limited default model is included for testing. BrowserOS's docs say local models handle page chat well but are not yet strong enough for Agent Mode. Hosted providers bill you for what the agent uses.
The agent acts in the browser where your logins and imported passwords live. Start with a read-only task and watch what it does before you schedule anything.
