Score: 7.0/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 7)

privacy-redact is a local-first privacy redaction library that detects and blurs sensitive text, faces, barcodes, and QR codes in images and PDFs entirely in the browser using WASM (Tesseract.js, face-api, ZXing), with a Node-safe text API. It combines multiple detection engines into a single review UI and emphasizes metadata stripping and irreversible redaction, filling a real gap between cloud OCR redaction services and manual editing.

Target audience: frontend devs, full-stack devs, privacy/security engineers
