How Med Guru cites every answer

The order matters more than the citation

An AI that writes an answer and then attaches a reference is doing decoration. The claim was already formed; the citation is chosen to fit. If the model was wrong, a plausible reference makes it more convincing, not less.

Retrieval-first inverts that. Your question is used to search a library of reference books, the most relevant passages are pulled out, and the answer is written from those passages. The reference is not evidence gathered in support of an answer — it is the source the answer came from.

If a claim has no passage behind it, there is nothing to cite, and that is the point at which the tool should say so rather than write a sentence anyway.

What happens between your question and the answer

• You ask in your own words. A mechanism, a first-line drug, a differential — phrased the way you would ask a study partner, not as a search query.
• The library is searched. Not the open web: a fixed set of reference books, indexed page by page, so a result can always be traced back to a physical location in a book.
• Passages are selected. The ones that actually bear on the question, with their book and page carried along.
• The answer is written from them, exam-focused and short, with each claim tagged by a numbered reference.
• You can open the page. Tapping a reference opens the real page it came from, so you can read the surrounding paragraph and judge for yourself.

Why opening the page is the part that matters

A citation you cannot check is a claim about a citation. Plenty of tools will show you a book title and a page number; far fewer will show you the page. The difference is whether verification costs you one tap or an afternoon in the library.

It also changes how you study. Reading the paragraph around the answer is where the context lives — the exception, the caveat, the adjacent fact the question did not ask about but the exam will.

What this does not do

It does not make the tool omniscient. The library has edges, and a question outside them gets told so instead of getting an answer assembled from memory. That is a deliberate trade: a smaller set of answers you can verify beats a larger set you cannot.

It is also not a substitute for judgement. Med Guru is a study aid for exam preparation and revision, not medical advice, and a cited passage is a starting point for understanding rather than the end of the question.
