Overview
A Flutter app where documents stay on the phone. It scans, reads aloud, edits, signs, protects and converts PDFs; cloud features such as generative AI are opt-in and consent-gated.

Our solution
On-device ML Kit for scanning, OCR and translation, Tesseract for Arabic, and on-device search and summaries. Generative answers go through a Cloudflare Worker only with consent, and synced files are end-to-end encrypted.
