Prospekt

Prospekt reads the pages you already visit and keeps the contact details it finds — emails, phone numbers, social profiles, and anything your own patterns match. No search box to fill in. No credits to spend. No account to create. You browse, it collects, and everything stays on your machine. WHAT IT DOES • Reads every page you open and extracts contacts as you go • Finds email addresses, phone numbers, and links to social and professional profiles — on any network, using patterns you control • Shows you what the current page gave up, before you navigate away • Marks what's new versus what you've already saved, so nothing is counted twice • Records where each contact came from — the page, the section, the date • Exports everything, or any filtered slice, as CSV WORKS ON ANY SITE Most contact finders only work on one professional network, or only on pages already in a vendor's database. Prospekt reads the text in front of you, so it works on a company's team page, a conference speaker list, a directory, a forum thread, a PDF viewer, or an internal tool your company built. If the text is on the page, Prospekt can catch it. YOUR PATTERNS, YOUR RULES Every pattern is a regular expression you can read and change: • Edit the email and phone patterns directly • Add or remove social platforms • Write custom patterns for anything you like — crypto wallets, SKUs, ticket IDs, case numbers, VAT numbers, order references • Test any pattern live against sample text and watch it highlight matches as you type, before you save it • Filter lists for domains to skip, junk email domains, role prefixes like noreply@, and social URL paths that aren't real profiles SEE WHETHER IT'S ACTUALLY WORKING Most extraction tools give you a pile of results and no way to judge them. Prospekt shows you: • Hit rate — what share of the pages you browse produce a contact • Yield per domain — which sites are worth revisiting and which are wasting scans • Pattern health — how many matches each regex has made and when it last fired, so you notice a pattern that's drifted before it fills your list with junk • Email quality — company domains versus free providers versus role addresses • Duplicates — the same value appearing across multiple domains PRIVACY Prospekt has no server. There is nothing to sign up for, and no analytics. • Every contact and scan record is stored in your browser's local storage • Nothing is sent anywhere — not to us, not to anyone • Remote favicons are off by default, because fetching them would tell each site that you're looking at your saved contacts • A skip list keeps Prospekt out of your mail, your documents and your messages • Clear everything at any time, from Settings Because the data never leaves your device, you are the only one who has it — and you're responsible for using it lawfully. Check the rules that apply to you before contacting anyone, including GDPR, CAN-SPAM, PECR and your local equivalents. WHO IT'S FOR • Sales and business development, building lists from real sites rather than a vendor's stale database • Recruiters sourcing from company pages, portfolios and community sites • Researchers and journalists collecting public contact points • Developers and analysts who want a configurable regex extractor in the browser • Anyone who has ever copied an email address by hand, twice FREE AND OPEN SOURCE Prospekt is free, with no paid tier, no credit system and no upsell. The source is public, so you can read exactly what it does with the pages you visit.
