Features & Capabilities
Everything you need.
Nothing you don't.
Three extraction modes, four validation tiers, multiple export formats — all running in your browser with zero server-side storage.
Three Ways to Extract
Choose the mode that fits your workflow. All three run entirely in the browser.
Paste & Extract
Paste any text — emails, HTML source, CSV dumps, log files — and get a deduplicated list of email addresses instantly.
- Regex-based extraction handles any format
- Handles millions of characters without freezing
- 100% browser-side — text never leaves your device
URL Fetch
Enter a URL and we fetch the page HTML via a Cloudflare Worker, then extract emails right in your browser.
- Edge proxy bypasses CORS restrictions
- HTML is discarded after extraction — never stored
- Scans mailto: links, visible text, and meta tags
Deep Site Crawl
Crawl an entire website — up to 1,000 pages — following internal links, collecting emails from every page.
- Configurable page limit (10 – 1,000 pages)
- Real-time progress bar with pages scanned / emails found
- Stays on the same domain — won't crawl external sites
Validation Engine
Four-Tier Email Validation
Not every regex match is a real address. Our four validation tiers help you separate signals from noise — all processing in the browser.
Regex Match
RFC 5322-compliant pattern captures emails from any text format.
Format Validation
Checks structure: valid local part, valid domain syntax, correct TLD.
Disposable Domain Filter
Flags addresses from known disposable/temporary email providers.
Role-Based Detection
Identifies role addresses (info@, support@, admin@) so you can filter them.

Domain Include & Exclude
Focus your results by filtering emails by domain. Include only corporate domains or exclude common free providers like Gmail and Yahoo.
- Include-list mode: only keep emails from specific domains
- Exclude-list mode: remove free email providers
- Combine both for precise targeting

Architecture
Privacy by Design
We didn't bolt privacy on as an afterthought. The entire architecture ensures your data stays in your browser.
- Paste mode: Text is processed by JavaScript in your browser tab. Never sent to any server.
- URL fetch: Cloudflare Worker fetches the page and returns HTML. Content is discarded immediately — no logging.
- Deep crawl: Same edge proxy, repeated per page. Each request is stateless — no session, no cookies, no history.
Real-Time UI
Watch the Crawl Happen
During a deep crawl, a live dashboard shows pages scanned, emails found, and crawl progress — all updated in real time.
