Cited answer

A cited answer is a reply that links straight back to the exact spot it came from, like a page number or a video timestamp, so you can open the source and check it yourself instead of just taking the answer on faith.

In more detail

When you study, a wrong fact you trusted can cost you in the exam. A cited answer fixes that. It shows you where the claim lives in your material, so you can read the original line and decide if the answer really matches it.

Under the hood it is simple. Each answer carries a pointer back to its source: page 14 of your lecture, minute 7 of the video, that one slide. You click it, you land on the real thing, you confirm.

The common mistake is treating any confident answer as a cited one. Confidence is not proof. If there is no link to a real source you can open, it is just a guess in a nice voice.

Example

Maria asks what her professor said about supply shocks. The answer points to page 22 of her lecture PDF. She clicks, reads the actual paragraph, and sees it lines up. Now she trusts it for the exam.

How StudyPDF does this

Bo answers only from the stuff you upload, and every answer links to the exact page or second it came from. If something is not in your material, Bo says so instead of making it up.

Common questions

Why is a cited answer better than a normal AI answer?

Because you can check it. A normal AI answer might sound right but be made up. A cited answer shows you the source, so you can open it and confirm the claim in seconds. For studying, that difference matters: you are revising from your real notes, not from a guess.

What if the answer cites a source but the source is wrong?

That can happen, which is why you still read the cited part yourself. The citation gets you to the right spot fast, but you decide if it actually answers the question. With Bo the source is your own uploaded material, so a wrong citation usually means your notes need a second look, not the tool.
