🔍 Lead Extraction Tool

An AI-powered lead extractor that scans websites to find email addresses and contact information.

How it works

Rendering mermaid diagram...

You enter a website URL in the form
An OpenAI Agent (GPT-4o-mini) receives the URL and uses a scrape_url tool
The agent strategically crawls the site — prioritizing about/team/contact pages
Emails are extracted from mailto: links and page text via regex
The agent returns structured lead data (email, name, role, source page)
Results are displayed in a table with a "copy all emails" button

Setup

Set the OPENAI_API_KEY environment variable → Get your key
