As answered by people managing Opalstack and PDF2Emails.
PDF2Emails's answer:
PDF2Emails is the only email extractor that runs 100% in your browser — your files never touch a server. On top of that it combines four things competitors split across multiple tools: text extraction, built-in OCR for scanned PDFs, SMTP verification, and AI enrichment, all in one flow that ends in a clean CSV. No other tool gives you that combination of privacy + OCR + verification + enrichment in a single, dead-simple product.
PDF2Emails's answer:
Because it is more private, more complete, and more affordable. Competitors upload your PDF to their server (a real concern when your file is a list of contacts); we never do. They make you jump between an extractor, a cleaner, and a verifier; we do it in one click. They price for the US/Europe only; we offer regional pricing with local payment methods (Wompi, dLocal Go) that work in LATAM. And you can start free — first 5 emails, no account — so you can judge quality before paying.
PDF2Emails's answer:
SDRs and sales teams, recruiters, freelancers, and marketing agencies — anyone who receives or handles PDFs (invoices, bank statements, resume exports, reports) and needs to turn the contacts inside them into a clean, verified, ready-to-use email list. The common thread: people who are tired of manual copy-paste and worried about uploading sensitive files to random online tools.
PDF2Emails's answer:
Built on Next.js, React, and TypeScript with Tailwind CSS, deployed on Vercel. PDF text extraction runs in-browser with pdf.js, OCR with Tesseract.js, SMTP verification for deliverability checks, and OpenAI for AI enrichment. Analytics via PostHog, and payments integrated with Wompi (LATAM) and dLocal Go (global).
PDF2Emails's answer:
I'm a solo founder who kept hitting the same boring problem: extracting emails from PDFs by hand, and feeling uneasy that the online tools I tried required uploading files that were full of other people's data. So I built the whole pipeline to run in the browser — extraction, OCR, verification, enrichment — which means my own files never leave my device, and neither do my users'. It started as a small micro-SaaS experiment and grew into a live, monetized product with regional pricing and SEO reach in five languages.
