In one click it reads a page, suggests the fields worth extracting, follows linked pages, formats or translates the data, and exports it to Google Sheets, Airtable, Notion, Excel, or CSV — no selectors or coding required.
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.
