Duna AI Scan is the fastest, most private way to scan and organize your documents on iPhone.

Point your camera, capture, done. Built-in AI auto-detects edges, removes shadows, sharpens text, and runs OCR locally — without uploading anything to a server.

WHY DUNA • Lightning-fast capture with auto edge detection and perspective correction • Import existing photos from your library — same Magic Filter & OCR as a fresh capture • Add pages to any document later, from the camera or your photo library • Magic Filter v2 with shadow removal — clean scans even under uneven lighting • On-device OCR (text recognition) in English and Vietnamese • Smart auto-tagging: invoices, receipts, ID cards, contracts, business cards • Auto-extract key fields: vendor, total amount, date, tax ID, due date, notes • Multi-page documents with reorder, rotate, crop, and re-shoot per page • PDF export, deterministic file naming, and clean folder organization

PRIVATE VAULT • Tap to lock any document with AES-256-GCM encryption • Unlock with Face ID, Touch ID, or your own passphrase • Blurred thumbnails so sensitive docs never preview accidentally • Anti-screenshot redaction on the lock screen • Encryption keys stored in iCloud Keychain — your private documents follow you across devices, encrypted end-to-end

ZERO BACKEND, FULL SYNC • Documents sync via your own iCloud account (CloudKit Private Database) • Nothing ever touches our servers • Sign in with Apple — no email, no password, no tracking

BUILT FOR PROFESSIONALS • Send any document JSON payload to your own webhook (Gateway tab in Settings) • Deterministic JSON Schema v1 — perfect for accounting and ERP automation • Future-ready for team workflows and BizConnex integration

PRIVACY FIRST • OCR runs entirely on-device using Apple's Vision framework • AI extraction uses Apple Intelligence (on supported devices) — never leaves your iPhone • No analytics, no third-party tracking SDKs, no behavior profiling • Banner ads are clearly labeled and respect App Tracking Transparency

ACCESSIBILITY • Dynamic Type • Full VoiceOver support on all primary screens • Reduce Motion respected

REQUIREMENTS • iPhone running iOS 17 or later • iCloud account (optional, for sync) • Apple Intelligence (optional, for advanced field extraction on iPhone 15 Pro and newer)
