What is Tesseract OCR?
Who uses Tesseract OCR?
Why developers like Tesseract OCR?
Here are some stack decisions, common use cases and reviews by companies and developers who chose Tesseract OCR in their tech stack.
I use Python because it's a beautiful (both visually and in terms of function) and multi-purpose language. In Paperless, Python is the primary connecting tissue holding all of the parts together: it's the basis of the consumption engine (communicating with Tesseract OCR via pyOCR) and the user-interface (based on Django).
I needed a tool that could convert a rasterised image into text. There are a few out there, but I don't think there's any that match Tesseract OCR for cross-language capability, community support and freedom (it's Free as in freedom and beer).
The setup isn't super-obvious, but once you've got it figured out, all of that can be automated. On top of that, there's lots of programming language-specific libraries out there that'll help plug your stuff into it.
