We strongly believe that everyone should have easy access to those agreements, in language they can understand. Legal Leaf works behind the scenes, in your browser, to read and summarize these terms using powerful AI. We're constantly working to improve the accuracy of these summaries.

    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!
