# Live browsing

> Every Quaso agent has a built-in browser, powered by Notte.

Every Quaso agent has a built-in browser, powered by Notte. It can navigate authenticated sites, fill forms, click through multi-step flows, and pull data from pages that do not expose an API.

Describe what you need and Quaso opens a browser when that is the best tool for the job. Built-in integrations are often faster and cheaper when they exist, so it is usually smarter to let the agent pick.

## What it can do

* Navigate complex pages: type, click, scroll dynamic content.
* Fill forms and walk multi-step flows.
* Extract data from tables, lists, and article bodies.
* Upload and download files.
* Hand sign-in or CAPTCHA back to you when a site demands it.

## Logins and CAPTCHAs

Quaso never asks for your password. When a site needs you to sign in or solve a challenge, the agent surfaces a live browser preview right in the conversation. You take over, do your part, hand control back, and the agent resumes.

## Persistent sessions

Each agent keeps its own browser profile. Once you have signed in through a preview, the agent stays signed in for future tasks; cookies and preferences carry over the same way.
