AI WORLD HQAsk Perplexity to Find and Cite Sources for a Topic You're Researching
Use Perplexity's cited answers to gather verifiable facts in minutes, with numbered footnotes that link straight to the original sources
In short: Perplexity gives you AI-written answers with numbered footnotes that link straight to the original sources, so you can collect verifiable facts for a paper, report, or decision in minutes — and you can start for free.
By the end of this guide, you'll know how to ask Perplexity a research question, read its cited answers, and turn those footnotes into a small, trustworthy set of sources. This is written for anyone doing research — a school paper, a work report, or a personal decision where you need verifiable facts, not guesses. Perplexity can search the web and cite its sources, but it cannot read paywalled articles for you; if a link takes you to a subscription wall, you'll need to check that one yourself.
💡 Tip: tap a step’s number when you finish it — a green tick appears and your browser remembers how far you got.
- A Perplexity account. The free plan is enough for basic research; a Pro plan adds deeper searches, file uploads, and more sources per answer.
- A web browser or the Perplexity mobile app (iOS or Android).
- A research topic in mind — even a rough one is fine.
- About 10–15 minutes for your first session.
Open Perplexity and start a fresh thread
Go to Perplexity in your browser (the official site is perplexity.ai) or launch the Perplexity app on your phone. The home screen shows a single search bar, usually with a placeholder like "Ask anything…". You don't need to log in to start a basic search, but signing in lets you save your threads so you can come back later. Once the page is ready, your cursor should already be blinking inside the search box.
If your screen looks different — perhaps showing trending topics or featured stories — ignore those and look for the plain search bar instead. On the mobile app, the search bar usually sits at the bottom of the screen rather than the top.
You'll know it worked when the empty search bar is clearly visible and your cursor is ready inside it.
Pick the right Focus mode
Look just below or beside the search bar for a small row of chips — these are Focus modes that tell Perplexity which kinds of sources to use. Common options include Web (the default, for general internet sources), Academic (peer-reviewed papers — useful for school), Social (discussions and posts), and sometimes News or Video. Click or tap one to select it; the chosen chip usually darkens or shows a small check mark.
If you don't see Focus chips, you're probably already on the default Web mode, which is fine for most topics. On older versions of the app or site, Focus may live behind a small icon or a settings menu — look for a label like "Focus" or a row of category icons.
You'll know it worked when a Focus chip is visually highlighted and your next answer will be limited to that source type.
Type your research question
Click or tap inside the search bar and type a clear, specific question about your topic. The more detail you give — a time range, a region, a viewpoint — the better the citations usually are. Press Enter on desktop, or tap the send arrow on mobile. Perplexity starts streaming its answer right away: sentences appear one by one, with small numbered markers like ¹ ² ³ next to factual claims. Those numbers are your citations.
If your screen looks different, the answer may take a few seconds to start streaming; longer or more specific questions usually need more time. If nothing appears after 30 seconds, check your internet connection and try your question again.
You'll know it worked when a multi-paragraph answer streams in and you can see at least one small numbered citation (¹, ², ³) attached to a fact.
Open the Sources panel and verify the citations
Scroll down below the answer on desktop, or look for a "Sources" button on mobile — there's almost always a clearly labeled list of references Perplexity used, usually in citation order. Each entry shows the publication name, the article title, and a clickable link. Click or tap any source to open the original webpage in a new tab; that's your chance to verify the claim in context rather than trusting the summary.
If you can't find the Sources section, look for a small link icon 🔗 or a numbered list at the bottom of the answer — Perplexity keeps them right next to the text. If the list is long, there may be a "View all" or "+ N more" link to expand it.
You'll know it worked when you can click a numbered citation, open the original page, and confirm the fact actually appears there in context.
Follow up to go deeper
If the first answer isn't quite what you need, ask a follow-up question in the same chat window. Type your new question and press Enter or tap send. Perplexity keeps the context of your previous question, so it understands pronouns like "that" or "this topic" without you re-explaining everything. The new answer will have its own fresh citations. You can also click any suggested follow-up questions that appear at the bottom of the answer to explore adjacent topics.
One honest caveat: asking Perplexity to confirm something you've already stated can produce a less balanced answer. If you want to challenge a claim, rephrase your question neutrally and let the sources speak for themselves.
You'll know it worked when a new answer streams in with fresh numbered citations, and the chat history on the left side shows your questions in order.
- Trusting the answer without checking the citation. Perplexity can occasionally get a number or quote slightly wrong, even when the source link is real. Fix: always click at least 2–3 of the cited sources and read them yourself before using the fact in your work.
- Writing a question that's too vague. "Tell me about climate change" gives a generic, weakly cited answer. Fix: add a time range, a region, or a specific angle — for example, "the impact of climate change on coffee production in Brazil since 2015."
- Stopping at the first answer. A single Perplexity reply is a starting point, not a finished research base. Fix: ask 2–3 follow-up questions from different angles and check that the cited sources are diverse — not all from one outlet.
Open Perplexity, type "What does peer-reviewed research say about the health benefits of drinking coffee?", and click any three of the numbered citations at the bottom of the answer. Read each source for two minutes. That's your first research session — done in under five minutes.
