Not op, but I wrote something equivalent based on a linux script that I found [1]. Here's the mac version of the script [2]. You need tesseract [3] installed for the OCR. For launching it using a keyboard shortcut I use a hammerspoon [4]. Example of how I bind it [5]

Nice, I started with tesseract, but moved to Google Vision as the quality was better.

Azure's offering was better for hand written notes.

Interesting, that doesn't really work for me as I sometimes use it to OCR sensitive stuff from scanned documents, and it wouldn't work offline. I found tesseract to work pretty reliably for my use and only fail when scanning non-ASCII characters.

Yeah, I only use it for things where the context wouldn't matter. For example grabbing an account number from a document.

I've been experimenting w/ CoreImage detectors (mainly for categorisation of scanned documents based on QR codes).

When I clean things up today, I'll see what can be used.
