Email Address Extractor

WHAT IT DOES

Email Address Extractor scans the current page's HTML source and visible text to find every email address. The tool displays each extracted email with its domain and optional surrounding context, making it easy to verify and organize the results. You can remove duplicate addresses, filter out specific domains, and sort the list alphabetically. A detailed breakdown shows total email count and the number of addresses per domain. Copy your emails in plain text or CSV format for use in spreadsheets, mailing lists, or contact management tools.

WHERE IT RUNS

The extension runs entirely within your browser's local environment using the BotGentz framework. All text scanning, email extraction, and processing occur on your machine without any network requests. No page content, email data, or user activity is ever transmitted, uploaded, or stored externally. The tool works on any website and respects the browser's security boundaries, operating within the isolated extension sandbox.

HOW TO USE

Click the extension toolbar icon to open the Email Address Extractor panel. Click "Extract Emails" to scan the current page and display all found email addresses in the preview panel. Each email shows its address, domain badge, and optional surrounding context. Use the "Copy Emails" button to copy all extracted addresses to your clipboard in the selected format. Change the output format using the dropdown (Plain Text or CSV). Toggle "Remove duplicates" to eliminate repeated addresses. Toggle "Sort alphabetically" to organize the list. Toggle "Include context" to show the surrounding text where each email was found. Use the "Exclude Domains" field to filter out addresses from specific domains (comma-separated). Adjust the "Minimum email length" to ignore very short addresses. The preview panel updates instantly when you change any setting.

THE EMAIL EXTRACTION ENGINE — WHY IT WORKS

Most email extractors use simple regex patterns that miss many valid email formats or capture false positives. This tool uses a comprehensive regex pattern that matches all standard email formats: [a-zA-Z0-9._%+\-]+@[a-zA-Z0-9.\-]+\.[a-zA-Z]{2,}. The engine scans both the HTML source and the rendered text content, ensuring it catches emails in attributes, comments, and visible text. The surrounding context feature extracts up to 40 characters on each side of the matched email, providing useful context for verification. The deduplication engine uses a Set-based approach to ensure each unique email appears only once. Domain filtering checks each address against a list of excluded domains, using substring matching to catch variants. The minimum length filter helps eliminate very short or malformed addresses. This multi-layer approach ensures accurate, comprehensive extraction with minimal false positives.

THE PANEL

The Email Address Extractor panel is fully draggable by its title bar and remembers its position on screen per website. It snaps to the edges of your browser window for clean alignment. Collapse the panel to a compact icon strip using the minimize button, restoring it with a single click. Resize the panel by dragging any edge or corner; the email preview and controls adjust proportionally. Press the Escape key to close the panel instantly. The panel maintains independent state for each browser tab, allowing you to extract emails from multiple tabs simultaneously.
