I've worked extensively in this space. For those looking for just an OCR solution MSFT's offering "read" is by and far the most accurate. Key-value, table and other information extraction is a much harder problem. Anything that can go wrong in production will. Documents with extra pages, rotated, blacked out, fuzzy. There are many steps that go into making document extraction really e2e.

The biggest enterprise users are doing thousand+ of pages a minute and also turn document extraction into a scaling distributed systems problem

Do you have any recommendations for OCR of receipts and grocery bills? I’ve dreamt of having a little app to analyse grocery spending and distribute bills among multiple people, but every time I checked, the state of receipt OCR was surprisingly too bad for this…

Last I checked I saw a grocery bill example using https://github.com/mindee/doctr and was fairly accurate. Bear in mind that was last year, hopefully it got even better or there are other libraries
