Email Radar – Extract Emails for leads and jobs

Email Radar instantly extracts every email address from any webpage — LinkedIn profiles, job postings, company directories, forums, and more. All processing happens 100% locally on your device. Zero data is ever sent anywhere. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔍 WHAT IT DOES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Click the Email Radar icon on any page and a clean side panel slides in showing every email address found. It works silently in the background as you scroll — new emails appear in real time without any manual action. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚡ KEY FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✅ Real-Time Detection Emails are detected the moment they appear on the page — no waiting, no page refresh. Works on dynamically loaded content (React, Vue, infinite scroll). ✅ Auto-Scan Mode Toggle Auto and Email Radar automatically watches for new content as you scroll. Every lazy-loaded section, feed update, and DOM change is scanned instantly. ✅ Context Snippets Each email shows the surrounding text so you immediately know who it belongs to and where on the page it was found. ✅ One-Click Export • Copy All — copies every email to clipboard (one per line) • Download TXT — plain text file with all emails • Download CSV — spreadsheet with columns: Email Address, Raw Match, Context, Extracted At (Excel-ready with UTF-8 BOM) ✅ Smart Deduplication Each unique email appears only once, regardless of how many times it appears on the page. ✅ Works Everywhere LinkedIn profiles, job boards, company About pages, team directories, forums, university sites, government portals — any page with text. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 100% PRIVATE — ZERO DATA SHARED ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Email Radar makes absolutely zero network requests. It never phones home, never logs anything, and never stores anything on disk. All extracted emails exist only in your browser's memory for as long as the panel is open.
