I have 85,000 PDF documents, collected over a few decades.

What I really want is a semantic interface to those PDF documents. Find me "all PDF files which mention ", or "show me any PDF with python example code", or "all PDF's before 2011 on the subject of coding standards for SIL-4".

I keep thinking this is out there somewhere, but whenever something new comes along I get bogged down in the details of setting it up. Surely someone has come up with an AI that you can just 'give the folder to' and it figures things out automagically?

Unfortunately, most of the PDF work I do involves things I’m not uploading to a service - ever. I don’t care if they’re “deleted immediately after processing” - they left my control. This sort of software would be great if it were 100% offline. This isn’t just a niche issue either: this is a very real consideration for any corporate user. More companies are taking data loss and security issues seriously, which often…

I work at https://www.pdf-tools.com and we hear this again and again.

Despite the proliferation of cloud services, most large enterprises DO NOT want their sensitive documents entering the cloud. And in some cases, e.g. patient medical records, there are strict regulations about how those documents can be stored, which means on-premise is a requirement.

Good news for us, as that's what we specialise in, but also perplexing how trends in the software industry can completely ignore what customers actually want.

And it stores it in local storage and uploads it using a service worker later when I'm online?

Use incognito mode then close that window before reconnecting online?

I'd suggest install a separate browser (there exists a myriad by now), unplug internet, use the service, uninstall the separate browser, reboot pc.

i used open source solutions to built it, like libreoffice, ghostscript, google's tesseract and a bunch of other tools, Google's Tesseract: https://github.com/tesseract-ocr/tesseract

I’m surprised everyone is using Tesseract. It was the only game in town 10 years ago, and it’s Ok on cleaned aligned data, but there are a few newer ones like EasyOCR [0] that can deal with much less organized text (albeit more slowly) [0] https://github.com/JaidedAI/EasyOCR

EasyOCR looks like it's more focused on the mobile use case of extract text from photos. That's a little bit different from extracting text from scanned documents, where document structure is an important aspect, and Tesseract is the devil we know. In the commercial space ABBYY Finereader still dominates - https://en.wikipedia.org/wiki/ABBYY_FineReader

But perhaps I'm wrong...

I suggest a separate VM for that, that you can delete when you're done. Add put the VM on a separate PC that you bought with cash off craigslist. Then toss the PC away in a different postcode when you're done. Then you can use the PDF tool safely without fear you're being tracked.

Am i missing something or does it lacks pdf editing functionalities like adding/editing text or adding images? I usually use https://smallpdf.com/edit-pdf because 99% of the times i simply need to compile fields with text and attach a png of my signature on some pages and resend the document to the organization that required me to compile it (schools, medical self certifications, governative tax entities and so on). For those need, smallpdf is fantastic, but obviously i'd prefer an opensource or simply a self hostable solution

Unplug your network cable when you use it.

And it stores it in local storage and uploads it using a service worker later when I'm online?

If that's your paranoia level: How do you know the "offline" tool you're using is not uploading to a server? Possibly inadvertently in the course of bug reports, or surreptitiously while contacting the license server...?

Should security concerns really warrant not trusting the (reputable) vendor that the files are not being uploaded, you would need to do some sort of audit and/or run in an isolated environment and wouldn't be the "random user" referred to in OP.
