MakeACopy

MakeACopy is an open-source document scanner app for Android that allows you to digitize paper documents with offline OCR functionality. The app is privacy-friendly and works completely offline — no cloud connection, no tracking.

Features:
• Camera scanning: Capture documents using your device’s camera
• Edge detection: Automatic document boundary detection using OpenCV, enhanced by a custom-trained ONNX inference model
• Perspective correction: Manually or automatically adjust document perspective
• Grayscale export: Optional grayscale filter applied during PDF creation
• OCR: Offline text recognition using PaddleOCR in the published paddle flavor
• PDF export: Save scanned documents as searchable PDFs
• Share & save: Export locally or share via other apps
• Dark mode: System-based Material 3 theme with light and dark appearance
• Privacy-focused: Fully offline — no data leaves your device

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.

MakeACopy is F-Droid compliant and builds native libraries from source during the build process, ensuring that no prebuilt binaries are included in the repository. All components are open source and respect your privacy.

MakeACopy is free and open source. If you find it useful, please consider supporting development: https://ko-fi.com/egdels

* New: every setting now lives in one options dialog, grouped into collapsible sections.

* Fixed: the bottom button bars span the full width and reach the bottom edge of the screen.
* Fixed: short messages no longer cover the buttons; they appear above the button bar and follow the light or dark theme.
* Fixed: camera preview and photo sometimes shrank to a landscape strip.
