For those interested in the technical side:

MakeACopy uses reproducible OpenCV/ONNX builds and runs Tesseract OCR fully on-device. The PDF text layer is generated with Apache PDFBox for full searchability.

All binaries are F-Droid–compliant and deterministically reproducible.

Happy to discuss the OpenCV/ONNX integration or how the deterministic build setup works.
