How does gpt4all parse pdf?

[bakaburg1]

Hello,

I understood that gpt4all is able to parse and index pdf, which contain (latex-generated) math notation inside. What does it use to do it? does it actually parse math notation correctly?

Thanks!

It uses QPdfDocument::getAllText:

gpt4all/gpt4all-chat/database.cpp

Lines 833 to 834 in ef518fa

	const QPdfSelection selection = doc.getAllText(pageIndex);
	QString text = selection.text();

I do not know how well it handles math notation. You would have to try it and find out.
