Client-Side PDF Redactor

A simple, privacy-first tool for redacting sensitive information from PDFs without uploading to external servers. Users can quickly blur or black out text (like salaries on paystubs) before sharing documents. Target: anyone who needs to share documents with sensitive data.

Privacy regulations like GDPR and CCPA have made document redaction a routine need for individuals and small businesses, and the rise of AI tools that scrape uploaded files has made users increasingly wary of server-side processing — client-side execution is a genuine selling point right now, not just a feature. Adobe Acrobat is the closest substitute, but it's expensive, complex, and overkill for someone who just needs to black out a salary figure before forwarding a paystub. The $500–2k/mo revenue band is realistic for a freemium or one-time-purchase model given the low support overhead and minimal infrastructure costs, though it's also a ceiling that's hard to break through without a B2B angle. The biggest risk is that browsers already handle PDFs natively and open-source libraries like PDF.js lower the barrier for a competitor to ship the same thing in a weekend, which makes differentiation and discoverability the core problem, not the build.
