I actually would buy Abbyy OCR but pricing for Linux ist just insane for private use. I just saw, the CLI is even discontinued: https://www.ocr4linux.com/
I've been trying to use it multiple times, but I can't find it effective. I'm sure they just have in mind different needs from the ones I have, because I can tell it's a nice project.
They (Abbyy) in my understanding are a good example of a lazy company, sigh. They find something valuable and extract the most out of the franchise with the minimun effort. A bit like Lastpass.
You can't deny they both excel at some stuff in their field but I still get pushed away by the lack of care/generosity.
The entire ABBYY FineReader product family is getting a new look and feel. Our online recognition tools will be reworked and introduced at a later date to demonstrate the power of ABBYY's OCR technologies."
They launched a cloud version a few years ago and have seen most growth there. It’s not the best API (it requires polling; no webhooks. Yuck), but it does include their latest engine at entry level pricing.
