AI and types of documents

I have typically saved my documents in DTPO as pdfs. But I happened to notice while watching some videos that most of the docs were saved as rtf.

So the question this raised for me is this: Does the AI in DTPO work better with rtf documents or with pdf documents? Or does it make any difference?

If the PDFs are searchable, there’s no particular difference.

Thanks. That’s good to know.
