Your scans, text, and data stay 100 % on your device.

Main features
• 📸 Camera scanning — Capture documents with your device camera

The F-Droid and Google Play listings provide the paddle flavor with PaddleOCR. The standard flavor with Tesseract remains available through GitHub Releases for users who still need Tesseract language data or workflows.
Every component is open source and respects your privacy.

Ratings and reviews

The best OCR app I've tested. The UI and UX have improved dramatically since my last review, and the app looks much more polished overall. There are still some minor inconsistencies (e.g. text too big in the main screen ...) but they are subjective. Also I think there is an aspect ratio bug on some devices, anyway the progress has been impressive. Looking forward to future updates and refinements. Maybe a feature like local AI to search through the docs and categorize them could be fantastic.

Does exactly what it says. Good replacement for disappeared cropping function from Google Photos. The only thing I would change is the possibility to default savings files as jpeg.

Scans to pdf. Simple is good. open source and no ads or tracking.

What’s new

* Improved black & white conversion: cleaner pages, fewer speckles, better readability of faint text and low-res scans.
