I am very new to this field, so forgive my ignorance when I ask super basic questions.

1. Does chat-with-pdfs function work with scanned PDFs? 2. In the video example for chat-with-pdfs you show uploading a document interactively. The part of processing is quite slow. Can the tool be fed these documents offline as well?

My use case for each user, there are many, to have their own list of documents that they upload. They come back later, after the LLM has had a chance to process all documents and can ask questions about their own documents only.

Is something like this possible?

Great questions.

> 1. Does chat-with-pdfs function work with scanned PDFs?

Not yet. We don't do OCR or anything to extract text from images yet. But that would be an awesome feature, so we would love to add it in the future.

Not as of right now. But we do have plans to make that an offline/background job so that we can feed a larger corpus of documents into it and query against it later.

If I've already run OCR on my PDFs and that's added now as an invisible layer, would it work then?

I've had a workflow digitizing my incoming paper documents, running OCR, and tagging them, all locally, and it would be great to have an easy front-end to talk to them.

I haven't tried this myself, but I think it should work. It would be worth trying at least, so I highly encourage you to play with it, and file issues if you find any issues with it.

I haven't found an OCR tool reliable enough when it comes to scanned PDFs containing financial data where accuracy of amounts in the document is very important.

People spend an inordinate amount of time and money solving this problem rather than spending the same amount of money in lobbying and standardization efforts for financial institutions. I’ll throw this out there: when all you know is a hammer, everything looks like a nail.

Have you tried Azure Document Intelligence? I've had very good results with it.
