I do find that if I submit a simple prompt I tend to get a simple answer, whereas a prompt with “completeness of query with the subject well fleshed out” elicits a more comprehensive answer.
Sometimes I have been too vague with Perplex. But when I went back and formed a more specific query, I get a much better answer.
Last month I asked Perplex a question about Social Secuity. It saved me money. (It’s a bit complicated)
