Agentic web scraper that turns any page into ready-to-use data
Open a page, click extract, and AI proposes the fields worth capturing and returns structured rows — no CSS selectors or drag-and-drop setup.
For popular sites like Amazon, eBay, and Google Maps, pre-built templates return consistent fields instantly without spending AI credits.
Thunderbit can open linked pages and pull details from them, so a results list and its detail pages become a single table in one run.
Summarize, categorize, translate, reformat, or calculate fields as part of the scrape, so exports arrive ready to use.
