Not OP, but I would definitely find a lot of value from processing PDFs in such a way that it could eg understand tables and images. I work in mining and having it digest a 43-101 technical report with images and tables would be supremely valuable.
I know that might be a niche case tho.
Absolutely incredible work you’re doing tho wow, I’m very impressed by what you’re doing and the way you’re doing it. Even if you stopped now this is a masterpiece, so while yes I would definitely find a lot of value from being able to process images and graphs/tables, simply being able to process the text and cite it is already a superpower. Thank you for your amazing work!!!
