I see there is an F-Droid compatible repo linked. Is there a reason it has not been submitted to F-Droid proper? Sounds like a perfect addition to the default repo.

I don't see anything on the readme about OCR. In the PDF conversion, does OpenScan do any OCR? I guess I expect this from a document scanning app these days, but I don't really know the space. Are there any good open-source OCR libraries?

Tesseract? The page does not refer OCR anywhere, neither does it appear on its issues.

There are no OCR capabilities. Just managed to get a good cropper implemented with perspective cropping. There were very few options of which only one was viable.

True. Have started the process. Hopefully it builds without much problems.

I would recommend https://github.com/PaddlePaddle/PaddleOCR over the default tesseract. It seems to do a better job these days and uses more modern approaches.
