Questions

Questions About Choosing

Is Thunderbit a direct alternative to ProfileSpider?
Partly. Both are AI-assisted Chrome extensions for extracting structured data from web pages. ProfileSpider is focused on lead lists and profile extraction, while Thunderbit is a broader AI web scraper and automation tool.
Which one is better for lead generation?
ProfileSpider is usually the better fit when the workflow is specifically about saving leads into lists, adding tags and notes, finding emails where available, and exporting lead files. Thunderbit is strong when the lead workflow also needs broader scraping, subpage extraction, app exports, or templates.
Which one is better for general web scraping?
Thunderbit is broader for general web scraping because it supports AI column suggestions, subpage scraping, pagination, infinite scroll, PDFs, images, templates, and app exports. ProfileSpider is more focused on people, company, profile, and lead extraction.
Can both export to Excel?
Yes. ProfileSpider exports to CSV, Excel, and JSON. Thunderbit also supports spreadsheet-style exports, including Excel and connected app exports.
Does ProfileSpider charge per extracted row?
No. ProfileSpider uses page-based credits: one page scrape uses one credit.
Can ProfileSpider replace Thunderbit?
Only for lead-focused workflows. If you need broad AI web scraping, subpage scraping, scheduling, PDF/image extraction, or exports to apps like Google Sheets, Airtable, and Notion, Thunderbit covers more categories.
