  I built a free and open source pdf redaction tool2025 · magicredact.com · ▲5

  Hey everyone, I recently built a free and open-source tool that lets you manually redact PDFs and images right in your browser—no sign-ups, no watermarks. I also added an AI-powered auto-redaction feature to detect and remove sensitive info. Since this part uses external processing (OCR + AI), there are usage limits: you can auto-redact up to 3 single-page PDFs or images for free each day. Higher usage and multi-page support require a paid account. Right now, it works great for removing sensitive details like names, addresses, and emails, but I’d love to get your thoughts: • What redaction…

  PDFly – 56 free PDF tools that run in the browserJul 2026 · pdfly.uk · ▲10

  Hi HN! I built PDFly — a PDF toolkit that runs entirely client-side. No file uploads, no server processing, no account needed. It has 56 tools including merge, split, compress, convert, redact, compare, and an AI chat feature to ask questions about your PDF content. Everything runs in your browser using [mention your tech stack if relevant, e.g., WASM/JS libraries]. Would love feedback on the tools, UX, or anything else!

  Hi HN, I built RedactMyPDF.com after struggling to manually redact a large legal PDF, and I found that existing tools were either expensive or clunky. RedactMyPDF uses AI (Gemini) + OCR + human review to make redaction fast but safe: Auto-detects sensitive info based on document context (names, addresses, IDs, etc.) Full control to accept, reject, or add redactions Works on scanned PDFs (OCR with Tesseract) Secure & GDPR-compliant (AES-256, EU storage, one-click deletion) Irreversible blackouts + metadata removal Audit logs (CSV export for compliance) Try it here: www.redactmypdf.com Thanks!

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
