Redactify is a fully offline, AI-powered Flutter app that empowers users—especially those from low-digital-literacy or rural backgrounds—to detect and redact Personally Identifiable Information (PII) from documents like PDFs, images, and text files. The app ensures data privacy while providing a beautifully interactive and intuitive UI.
AI for Safer, Smarter & Inclusive Bharat 🇮🇳
India's digital transformation has made data sharing common, but many citizens—especially in rural or semi-literate communities—unknowingly upload sensitive documents (like Aadhaar, phone numbers, bank info) without redaction.
🔒 There's a lack of tools that work offline, in Indian languages, and are simple enough for first-time smartphone users.
Redactify is an offline PII Detection & Redaction mobile app that allows users to:
- 📁 Upload PDFs, images, or text
- 🔍 Detect PII using OCR + AI (Aadhaar, phone numbers, passport, etc.)
- 🧹 Choose what to redact
- ✨ Redact the content with one click
- 📤 Download or share the sanitized file
- 🧾 View audit logs of redactions
Built using:
- 🧠 ONNX-based AI models (for NER)
- 🔤 Tesseract OCR (with Hindi/Marathi support)
- 🧪 Regex/NLP for contextual analysis
- 📡 Fully offline-first architecture
