Everything runs on your device — no account, no server, no upload. ## Facts - Made by: Sakura5 - Platforms: iPhone, iPad and Mac (iOS, iPadOS, macOS) - Status: available on the App Store - Pricing: AIPDF is free with no time limit for reading, annotating and up to 3 scans a day; AIPDF Pro costs $19.99 per month or $69.99 per year, both with a 3-day free trial, and one subscription covers iPhone, iPad and Mac. - App Store: https://sakura5.app/go/aipdf?from=/aipdf/ - Privacy: https://sakura5.app/aipdf/privacy · Terms: https://sakura5.app/aipdf/terms · Support: https://sakura5.app/aipdf/support ## What it does - **Scan paper into a real PDF** — On iPhone and iPad, the camera finds the page edges, straightens the shot and applies colour, greyscale or high-contrast filters. Keep shooting and every page lands in the same file. - **On-device text recognition** — OCR reads a photographed page into real, searchable, selectable text using Apple's Vision framework. The "AI" here is on-device document detection and text recognition — there is no generative AI and no server. - **Annotate and mark up** — Highlight, underline, strike through, draw freehand, add arrows, shapes and sticky notes — free, with no time limit. - **Sign and fill forms** — Draw your signature once, then drop it on any document with a tap. Fill form fields and tick boxes without printing a thing. - **Merge, split, compress** — Combine several PDFs, split a long one, reorder, rotate, delete or extract pages, and shrink a heavy file so it fits an email limit. - **Lock and unlock** — Add, change or remove a password on documents you own — the file is encrypted on your device, and no password ever leaves it. ## How it works 1. **Bring in a document** — Scan a printed page with the camera on iPhone or iPad, or import a PDF, photo or file — on Mac you import from Photos and the file system. 2. **Work on it** — Annotate, sign, run OCR, reorder pages, merge, split, compress or convert. 3. **Share or lock it** — Export from the share sheet, or add a password first. The original never leaves your device unless you send it. ## Privacy AIPDF is built by Sakura5 and does all of its work on your own device. There is no account, no sign-up, and no AIPDF server. Your documents are stored in the app's sandbox on your device, and scanning, text recognition (OCR), annotation, merging, compression and password protection all run locally with Apple's PDFKit and Vision frameworks. Your documents are never uploaded to us or to anyone else. - Nothing about your documents. AIPDF collects no personal data: the app's privacy manifest declares no collected data types and no tracking. Your PDFs, scans and recognised text stay on your device. - Camera frames while you scan (iPhone and iPad only) — processed on-device to detect and straighten the page, then written into your PDF. Nothing is streamed anywhere. - App settings and preferences — stored locally on your device. - Purchase status — used to unlock and restore your subscription (see Third parties). ## FAQ **What is free in AIPDF, and what needs Pro?** Free forever: reading and searching unlimited PDFs, highlighting, underlining, strike-through, drawing and notes, tidying pages, and up to 3 scans per day. Pro unlocks unlimited scanning, OCR, signing and form filling, merge and split, compression, convert/export and password protection. **How much is AIPDF Pro?** $19.99 per month or $69.99 per year, each starting with a 3-day free trial. Prices are in US dollars; the paywall shows your local price before you confirm. One subscription covers iPhone, iPad and Mac. **Are my documents uploaded?** No. Scanning, OCR, annotation, merging, compression and password protection all run on your device. There is no account and no AIPDF server, so the app also works offline. **Can I scan on the Mac?** Camera scanning is on iPhone and iPad. The Mac version imports photos and files instead; every other tool works the same. **Can AIPDF edit the text inside a PDF?** No. It annotates, signs, fills form fields and reorganizes pages, but it does not rewrite existing text or images in a document. **Who makes AIPDF?** AIPDF is made by Sakura5, an independent app studio that builds focused, privacy-first apps for iPhone, iPad and Mac.
