About this extension
LeadHarvest AI is a powerful Google Maps lead scraper that runs entirely in your browser — no subscriptions, no external accounts, no data sent anywhere.

How it works:
Open Google Maps, search for any business type (e.g. "dentists in Chicago"), then add the search as a task. LeadHarvest AI will automatically scroll through the results and extract the data you choose.

Key features:

🗂 Queue System — Add multiple search tasks and run them one after another automatically. Pause, resume, skip, or stop at any time.

📧 Advanced Email Extraction — Visits each business website and uses 9 different strategies to find a real contact email, including Cloudflare-protected pages, obfuscated text (name [at] domain), HTML entities, JSON-LD structured data, and more.

🎯 Selective Fields — Choose exactly which fields to extract per task: Name, Phone, Email, Website, Address, Rating, Reviews, Hours.

🔍 CMS Fingerprinting — Detects what platform each website runs on (WordPress, Shopify, Wix, Squarespace, Webflow, Framer, etc.).

📢 Google Ads Detection — Flags sponsored listings separately so you can identify businesses actively spending on ads.

📊 Records & Export — Filter leads by email, website, ads, or task. Search by any field. Export as CSV anytime.

🔒 100% Local — All data stays in your browser. Nothing is sent to any server.

Best for: freelancers, digital marketers, sales teams, and SEO agencies looking to build targeted lead lists from Google Maps.
