Status:Available — Published on Google Play. Verified 15 November 2026.
The problem
Many scanner apps upload documents to remote servers, and people regularly scan IDs, financial and medical papers that should never leave their device.
The solution
AI PDF Scanner captures, enhances and recognises text entirely on the phone. The release build has no internet permission, so documents stay on the device by design.
What it does today
- Automatic edge detection, perspective correction and image enhancement.
- Batch scanning of multiple pages into one PDF, or export to JPG.
- On-device text recognition (OCR), with editable, copyable text.
- Translation of scanned text on the phone, and voice dictation for editing.
- PDF tools: merge, split and add a signature.
- Document library and sharing through the system share sheet.
- Works fully offline — no internet permission, no account, no ads, no tracking.
- Optional app lock with the phone’s PIN or fingerprint.
