Yes, you heard right - it is 2019 and I STILL do not have any way to OCR an image natively in macOS Catalina. And no, Notes sucks. I do not want to OCR and index images, I want to convert images to text I can copy and paste and work with. To the best of my knowledge Notes only OCRs and indexes content to make it searchable, it does not allow you to copy text.
OneNote's OCR sucks. I'll add an image and after 30 minutes there is still no option to copy the text. Sometimes it takes up to an hour. That makes it a no starter.
It is 2019 and I assumed by now we will have native OCR support in our operating systems. So disappointed. At least I found this, but I should not have to.
