I found some topics about Hazel and OCR but it seems like most of you are using PDFpen Pro to get the OCR layer.
I wanted to ask if someone has a free tool which can accomplish the same. I dont need a new PDF editor, because I have PDF expert and it fits for everything I want to do, exept the OCR thing. I already mailed them but as far as i know this feature is not available.
What I want is (maybe a terminal tool - I think there is something available with brew) a tool which can apply the OCR layer in the background.
EDIT: solution in last reply
