I did some exploration using LLMs to parse, understand then fill in PDFs. It was brutal but doable. I don't think I could build a "generalized" solution like this without LLMs. The internals are spaghetti!

Also, god bless the open source developers. Without them also impossible to do this in a timely fashion. pymupdf is incredible.
