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?
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.
