Paperix - PDF Secure and Local

Scan to searchable PDFs and ask AI questions about them — all on your iPhone. No accounts, no cloud, no tracking. Your documents never leave the device.

Paperix is a fully free document scanner that runs everything — scanning, OCR, and AI — on your iPhone. No subscriptions. No watermarks. No ads. No upsells. No accounts. No cloud. Stop paying a yearly fee just to turn paper into a PDF, and keep your documents on your own device.

EVERY FEATURE OF THE PAID APPS — FOR FREE You shouldn't have to pay a recurring fee to turn paper into a PDF. Paperix matches the paid scanners feature-for-feature and charges $0 for any of it:

• One-tap multi-page scanning with auto edge-detect and perspective correction
• Black & white mode for receipts, faint print, signed contracts
• Maximum-punch filter for the cleanest possible output
• Reprocess any saved scan — switch Color / B&W / Max Punch later without rescanning
• Auto-name scans from the largest text on the first page
• Import from Photos or Files (PDFs, images, iCloud Drive, Dropbox)
• Save to Paperix from any app's share sheet — send one photo or a whole stack and they land as cropped, scanned documents
• Folders, sort, bulk select, swipe-to-share, 30-day Recently Deleted

SEARCHABLE PDFs OUT OF THE BOX — NO PREMIUM TIER Every scan runs through on-device text recognition. PDFs are searchable in Paperix, in Preview on your Mac, in Adobe Acrobat, anywhere. Pull down the list to search across every doc and tap a result to jump straight to the highlighted phrase. No "OCR credits". No paywalled search.

• Extract Text — Paperix: a share-sheet action that pulls the text out of any image with Copy and Share, without even opening the app — layout preserved, columns aligned

SIGN, FILL, AND MARK UP — NO WATERMARK

• Pen, Eraser, Undo, Redo, Clear in one toolbar
• Real ink colors: true black, red, blue, green, yellow
• Type text directly on a page — drag the dashed box anywhere, resize, pick size and alignment
• One-tap presets drop today's date or your saved name for forms
• Pinch-to-zoom canvas for tight signatures
• Draw with finger or Apple Pencil
• OCR re-runs on save so signed pages stay searchable

ON-DEVICE AI — ON YOUR IPHONE, NEVER ON A SERVER Every word of AI inference runs on your iPhone's Neural Engine using Apple's Foundation Models. Nothing is uploaded. Nothing is logged. Nothing is ever seen by anyone but you.

• ANALYZE a document — on-device Summary, Key Points, and per-doc Q&A
• ASK PAPERIX — pose a question across every doc on your phone and get a sourced answer with tappable citations back to the exact page
• Semantic search by meaning, not just keywords
• AI surfaces hide cleanly on iPhones without Apple Intelligence; the rest of the app works the same

The cloud scanners ship your private contracts, medical records, and bank statements to someone else's GPU. Paperix runs the same AI on your own phone. Your iPhone makes that possible — and free.

SMART ACTIONS FROM A SCAN Paperix looks for contact info, appointment dates, addresses, and links in every scan. One tap adds the contact to Contacts, the appointment to Calendar, the address to Maps, or opens the link in Safari.

EXPORT ON YOUR TERMS

• Standard PDF for everyday sharing
• Password-protected PDF for anything sensitive
• AirPrint to any printer on your network
• Standard iOS share sheet — Mail, Messages, AirDrop, Files, anywhere

PRIVATE BY ARCHITECTURE Paperix literally has no network code. Not "encrypted in transit" — no transit at all.

• No accounts, no sign-up
• No cloud sync, no telemetry, no analytics, no SDKs
• No ads, no upsells, no "premium tier"
• Verifiable with Little Snitch / Lulu. Turn airplane mode on permanently and Paperix works exactly the same.

REQUIREMENTS

• iPhone running iOS 16 or later
• Apple Intelligence-capable iPhone for AI features (iPhone 15 Pro and later); the rest of Paperix works on every iPhone with a camera
