Thunderbit
Freemium
Extract structured data from websites, PDFs, and images using natural language prompts, then export results to spreadsheets or databases via browser extension, API, or CLI.
About
Thunderbit is an AI web scraper for when you need a webpage turned into a spreadsheet without writing code. It runs as a Chrome extension, though there is also an API and CLI for developers.
You describe what you want in plain language. The AI suggests fields, you verify them, then it extracts and exports to Google Sheets, Airtable, Notion, Excel, or CSV.
It sits in Data & Analytics work, but leans toward quick tasks rather than ongoing systems. The free tier is six pages per month. Paid plans start around $15-20 monthly.
Open it if you need a one-time table from a page you can browse. Skip it if you need reliable automation that runs without you.
Who Thunderbit is best for
It fits narrow jobs where the setup speed matters more than the long-term reliability.
- Sales teams building lead lists: You pull contact info and subpage details fast. You still verify the output before you use it.
- Marketing analysts tracking competitors: You grab prices or listings once in a while. You do not need it to run on a schedule.
- Real estate agents gathering property data: You aggregate listings from multiple sites. You check the fields by hand each time.
- Researchers and analysts: You need structured data without learning CSS selectors. You accept that you will clean the results.
- Non-technical users with occasional needs: You stay on the free or low tier. You do not push enough volume to hit credit limits.
- People who prefer browser-based tools: You work entirely in Chrome. You do not need headless or scheduled runs.
- Anyone doing ad hoc market analysis: You extract once, get your table, and move on. You do not maintain a pipeline.
Best things about Thunderbit
These are the parts that work well enough to keep you coming back.
- AI field suggestions: You skip writing CSS selectors. The AI proposes columns based on what it sees on the page.
- Subpage scraping: You stay on a list page while it visits linked details. You get enriched data without writing a spider.
- Direct exports: You send results straight to Google Sheets, Airtable, or Notion. You do not download and re-upload.
- Browser mode for logged-in pages: You scrape sites that need your session. You do not configure proxies or logins separately.
- Natural language prompts: You describe what you want in plain words. You do not learn a visual workflow language.
How you use Thunderbit
The first run feels almost too easy.
- Install the Chrome extension and open the page you want to scrape.
- Click the extension and hit "AI Suggest Columns" to see what it thinks you want.
- Review the fields, adjust any that are wrong, then run the extraction.
- Export to your tool of choice and check the data for errors or gaps.
Why you should ignore it
There are real limits that push people away after the first try.
- Skip it for production workflows: The tool is explicitly not built for ongoing monitoring. You will babysit every run.
- Skip it if you need scheduling: There is no autonomous maintenance or scheduled scraping. You trigger everything by hand.
- Skip it at entry price for volume: The cheapest paid plan covers roughly 3,000 pages per year. You burn through that fast.
- Skip it if you hate billing surprises: Multiple users report aggressive charges, unclear trial terms, and $199 annual defaults. You may spend time disputing.
- Skip it for silent reliability: Layout changes break field detection without warning. You find out by spotting bad data, not an error.
- Skip it if you need debuggability: When the AI guesses wrong, you cannot inspect why. There is no selector to fix.
