How serendipitous. I was looking for something like that recently. Admittedly my use case was much simpler, detecting tables of contents on scanned pdfs that usually don’t have them as links to navigate within the document. Will see if this could help. Is anyone using something else for my use case?

Not sure what your budget is but I’ve used AWS for handling PDFs and it’s been pretty good at detecting content via boundary boxes.

AWS as in Amazon Web Services? And if so, can you be more specific?

Here are some more options:

* AWS Textract [0]

* Microsoft Azure [1]

* Google Cloud Vision [2]

I personally use Azure, combined with OCR correction using GPT to convert a scan of my daily journal (Apple Notes creates a PDF that is nothing but a bunch of images) -> Markdown -> Extract tasks and then add them to my Reminders app using CalDav. Azure has one of the best OCR for handwritten text, but for normal document extraction (read: printed text), any service would do a reasonable job.

Could you explain how you use GPT for ocr correction?

This is the prompt I bought from promptbase. You basically provide GPT with some examples on possible OCR errors, and then you give it the OCRed text and it tries to correct it

Fascinating. Thanks!
