How do I make my AI assistant cite sources before answering?
Add four words to your question: sources first, then answer. The assistant lists two or three cited titles above its conclusion, so you check the claim against a citation before reading it. In one test, a confident line said 2021 while its own cited page read 2019 — the gap was visible with zero clicks.
How to do it
- Ask your factual question as you normally wouldWrite the question you actually want answered, without changing the wording. The fix is only about ordering the response, not the question.
- Add the instruction: sources first, then answerAppend these four words so the assistant lists its citations before stating the conclusion. This flips the default order that hides the sources below the claim.
- Read the cited titles before the conclusionSkim the two or three sources on top first. You arrive at the answer already set up to judge it, not just to accept it.
- Compare each cited page against the stated answerCheck whether a number, date, or fact in a citation actually matches the conclusion. A mismatch — like 2019 in the source versus 2021 in the answer — flags a guess with no extra click.
Questions that come up
Does this work with every assistant?
It works with any assistant that can browse or cite, including ChatGPT, Claude, Gemini and Perplexity. If the tool has no access to sources, it may still list plausible-looking titles — so treat missing or vague citations as a warning rather than proof, and open one to confirm it exists.
What if it returns no real sources?
That itself is the signal. When an assistant can only offer its own wording with no page to point to, the answer is unverified — the confidence is not evidence. Ask it to say plainly when it has no source, and lower your trust in that specific claim accordingly.
Isn't reading sources first slower?
Slightly, but only when it matters — you would not do this for casual questions. For a fact you'd otherwise have to double-check anyway, seeing the citation inline is faster than opening a separate page, and it catches the confident-but-wrong answers that are hardest to spot.

When the answer matters, tell your assistant: sources first, then answer. The default buries the citation — you get one confident line, no link. Ask sources first, and the cited page reads 2019 while the answer still says 2021. The gap sits right there — checking took no click. Next time it matters, add: sources first, then answer.
