Windows has had an offline OCR API for ages. This is based on the phone link software that exchanges files

You can always use the existing offline code this is obviously based on or compile it from source.

I wish Linux distro would come with an API like this. Microsoft, Apple, and Android all come with offline OCR engines to select text from images yet on Linux I’m still running tesseract like a fool. KDE Connect stopped supporting proper clipboard sync so exchanging text from pictures on my phone sucks now.
