Frequently Asked Questions

What is a browser agent?▾

A browser agent is an AI that can autonomously control a web browser — navigating pages, clicking buttons, filling forms, and extracting information. Unlike traditional scrapers, browser agents can handle dynamic websites and make decisions.

How reliable are browser agents?▾

Reliability varies by task complexity. Simple, well-defined tasks are highly reliable. Complex multi-step tasks across unfamiliar websites still have meaningful failure rates. The technology is improving rapidly.
