How does this work? Do you first scrape the PDF or do you have gpt4 multimodal access? The privacy policy link is broken at the moment so I can’t tell for sure

I can't answer for theirs but I made one too:

The way it works is you first parse the PDF to analyze its text, then use a LLM along with the relevant text when answering user questions.

Can you elaborate on how you parse the PDF? Are you simply converting it to text using a python library or something more robust like GROBID[1]?

Not the OP but I that's what I do.

Do you know of anything that can process engineering drawings and diagrams by looking how lines link text and other objects?

You just upload your pdf doc directly or via a url and you are good to go.

I think the GP was interested in technical details. Specifically, do you first scrape the pdf (using another tool presumably), or do you have gpt4 multimodal access?
