For about a year now i am working on an iOS Application that requires good OCR. With the release of iOS 13 Apple has added an API for this in their Vision Framework and i have to say i am shocked how good it works. It works completely on device and, according to Apple, uses Machine Learning.

You can feed it an image that contains text, with the only constrained being that the text should not be rotated. Depending how much text there is it can digitize a 12MP image in about .5 to 2 seconds on an iPhone Xs.

I compared it to ABBYYs OCR SDK and i have to say Apple's OCR outperforms it nearly every time both in speed as well as in recognition quality. I am still fascinated by it and would really like to know how this is working under the hood.
