Questions & Answers

As answered by people managing PDFTrackr and mlsql.

Which are the primary technologies used for building your product?

PDFTrackr's answer

Next.js, TypeScript, PostgreSQL, React, Docker, DigitalOcean, Cloudflare

What makes your product unique?

PDFTrackr's answer

It's the only PDF tracker that shows you which views were real. Bots and email scanners are filtered out of your counts automatically, and the dashboard shows exactly what it removed. Then Signals tell you who came back and who's worth a follow-up, with a per-recipient verdict on whether a specific person read it, so you act on real buyers instead of inflated numbers.

Why should a person choose your product over its competitors?

PDFTrackr's answer

Most trackers count every open, including bots and email scanners that never read a word. PDFTrackr filters them out and shows its work, so the numbers are real. Then Signals do the analysis for you: who's genuinely engaged, who's worth a call now, plus a per-recipient verdict and real-time alerts with emailed Reading Reports. Full page-by-page analytics are free with a 12-month history and virus scanning, no credit card; Pro is $9/month or $84/year.

How would you describe the primary audience of your product?

PDFTrackr's answer

Sales and business-development teams, consultants, agencies, and founders raising on a pitch deck. Anyone who sends proposals, decks, and reports and needs to know who actually read them and when to follow up.

What's the story behind your product?

PDFTrackr's answer

Built to answer the question every sender has: did they actually read it, and when should I follow up? Instead of a vanity view counter that inflates numbers with bots, PDFTrackr filters out the noise and turns real reads into a shortlist of who's worth a call.

Who are some of the biggest customers of your product?

PDFTrackr's answer

  • Sales and business-development teams
  • Consultants
  • Agencies
  • Founders sharing pitch decks
