Score: 6.7/10 (Innovation: 6, Technical: 7, Documentation: 6, Utility: 7)

Redenta is a browser-based document redaction tool that permanently removes text by rasterizing pages and rebuilding PDFs as image-only, unlike common tools that merely cover text with black boxes. It includes metadata stripping and format conversion, runs entirely offline, and has a built-in guard that refuses export if any font object survives. The project addresses a real security gap with a thoughtful, transparent approach.

Target audience: legal professionals, journalists, privacy-conscious users, security engineers
