How to Fact-Check a Viral Claim or Breaking News Story with Perplexity

Use Perplexity's source-cited answers to see who said what, where, and when — all in about ten minutes.

6 min read·September 10, 2026

This guide was written by AI. It passed automated fact and quality checks; no human editor reviewed it.

A shocking headline lands in your group chat at 9 p.m. Before you forward it, paste it into Perplexity and you'll see — in plain English, with citations attached — what the underlying sources actually say, who first said it, and when. This guide walks you through five concrete steps written for someone who has never opened Perplexity before. The whole routine takes about ten minutes the first time, and less once you've done it a few times.

💡 Tip: tap a step’s number when you finish it — a green tick appears and your browser remembers how far you got.

✅ Before you start
  • A free Perplexity account (sign up with email, Google, or Apple — about a minute).
  • A web browser, or the Perplexity mobile app on iOS or Android.
  • The claim or headline you want to check, copied exactly as you saw it.
  • Roughly 10 minutes the first time.

Step 1 of 5

Open Perplexity and paste the exact claim

Go to the Perplexity homepage in your browser, or open the app. You'll see a chat-style page with a large text box in the middle and a small "Search" button or send arrow beside it. Click inside that box and paste the claim you want to check, exactly as you saw it — including any numbers, names, or quotes. Press Enter. Perplexity begins searching the live web and writes back a short paragraph answer with small numbered links (like [1], [2], [3]) at the end of each sentence.

💬 Example`A widely shared post claims a major bank will close 200 branches next month.`
🔄 If it looks different

If you can't find the search box on mobile, look for a magnifying glass or a "+" icon at the bottom of the screen.

✅ You'll know it worked when

you see a written paragraph answer with numbered citations at the end of each sentence and a list of source links below it.

Step 2 of 5

Read the inline citations and click into at least two sources

Look at the small numbered marks [1], [2], [3] after each sentence, then scroll down to the "Sources" panel that lists each linked page with its publication name. Click at least two of those links to open the original articles in a new tab. Read the relevant paragraph in each one yourself — this is the step most people skip, and it's the one that protects you from being fooled by a confident-sounding AI summary. If the citation numbers are hard to spot, Perplexity sometimes shows small preview cards beside the text instead — click those.

💬 Example(no typing required — just click the numbered links under the answer)
✅ You'll know it worked when

you've actually opened two of the linked pages and read the exact paragraph each one uses to back up the claim.

Step 3 of 5

Switch the Focus to get the right kind of sources

Look for a small "Focus" selector above or next to the search box — usually a row of buttons or a dropdown labeled with options like All, Web, Academic, Social, News, or YouTube. Pick the focus that matches what you're checking: choose News for breaking stories, Academic for health or science claims, Social for tweets and posts. Perplexity then narrows its next search to that type of source, which makes the results far more useful.

💬 Exampletap **News** if you're checking a breaking story, or **Academic** if the claim is about a medical or scientific finding.
🔄 If it looks different

If you don't see a Focus row, look for a "Sources" filter, a small gear icon near the input box, or a "⋯" menu in the corner — apps move these controls around.

✅ You'll know it worked when

the sources listed under your next answer are mostly news outlets, academic journals, or whichever focus you chose.

Step 4 of 5

Ask Perplexity to trace where the claim first appeared

In the same chat thread, type a follow-up question that asks for the origin: who first said this, when, and on what platform. Perplexity runs another search and answers with citations pointing to what looks like the earliest mention it can find — sometimes a tweet, sometimes a press release, sometimes a news article. If it tells you it can't find a clear origin, that itself is a useful signal: the claim may not have a traceable source. Keep in mind that Perplexity searches the live web, but a story that's only minutes old may not yet be indexed — if you see "no results found," wait a few minutes and try again.

💬 Example`Who first made this claim? When and where did it originally appear?`
✅ You'll know it worked when

you can name a date, a person or outlet, and a link that matches the earliest appearance of the claim.

Step 5 of 5

Cross-check with a fresh, differently-worded search

Open a brand-new thread — look for a "+ New Thread" or "Search" button at the top of the page, or simply open Perplexity in a new browser tab. Ask the same claim using different words. A second independent answer appears with its own sources. Compare the two answers side by side: do they point to the same underlying outlets, or do they disagree? Two searches agreeing on the same sources is a strong signal; two searches disagreeing means the claim deserves more digging before you trust it.

💬 Exampleinstead of pasting the original post, ask `What did the bank actually announce about branch closures this month?` in your own words.
✅ You'll know it worked when

two independent searches point to the same underlying sources, or — when they don't — you have a clear list of what to investigate further before sharing.

⚠️ Common mistakes
  • Trusting the AI summary without opening the citations. Perplexity's summary can still be wrong, vague, or outdated. Fix: always click at least two of the numbered links and read the source yourself.
  • Mixing up the publication date with the date of the event. A 2024 article about a 2019 event is not "news from yesterday." Fix: check when each linked article was actually published before you treat it as evidence.
  • Sharing the answer before checking that the sources actually support it. Sometimes the citation points to a page that doesn't quite say what the summary claims. Fix: if a source doesn't back the claim, the AI answer is unreliable — don't forward it.
