AI WORLD HQFact-check a viral claim with Perplexity before you share it
Run a shocking headline through Perplexity to see what the actual sources say — in 60 seconds.
In short: Perplexity (an AI search tool) searches the web and shows you the actual articles behind any claim, so you can decide for yourself whether a viral headline is true. You do not need to create an account to start — you can try it right now on the website.
You see a headline in your group chat. It sounds shocking. Your gut says it could not possibly be true — or maybe it could. Before you forward it with a "Can you believe this?" comment, there is a quick way to check: type the claim into Perplexity. It will pull up real articles and show you what reliable sources actually say. This guide walks you through that in about 60 seconds.
💡 Tip: tap a step’s number when you finish it — a green tick appears and your browser remembers how far you got.

Open Perplexity in your browser
Type perplexity.ai into your address bar and press Enter. The homepage loads with a clean search bar right in the center of the screen — a large white box that says "Ask anything" with a microphone icon on the right side. You may also see a few suggested questions below the bar. If you see a sign-up prompt in the top-right corner, you can dismiss it or ignore it; the free version works without logging in. Some features (like saving your search history) require an account, but looking up a claim does not.
You'll know it worked when you see the Perplexity logo at the top and a central search box ready to accept your text.
Type in the headline or claim you want to check
Click the search bar and type the exact headline or claim you saw. You do not need to clean it up or rephrase it — paste it as-is, even if it is messy or full of CAPS. Perplexity will search across the web to find articles that discuss the topic. For the best results, include just enough context for the search to understand the topic: the main noun, event, or person the claim is about.
You'll know it worked when your text appears inside the search bar and you can see a blinking cursor or the microphone icon waiting for your next action.
Read the answer and check the cited sources
Press Enter or tap the search button. Perplexity generates a short answer at the top — a plain-language summary of what it found. Directly below that answer, you will see a list of source cards: small boxes showing the name of each article or website, the publisher, and a small icon representing the type of source. Each card is clickable. The most useful part of this screen is reading what those real articles say — not just Perplexity's summary. If you scroll down, Perplexity may also show you a "Related questions" section that breaks the topic into smaller angles. If you do not see any sources listed, try rephrasing the claim or adding a key name or date.
You'll know it worked when you see a blue or underlined list of clickable sources appearing below the answer.
Open one or two sources to verify the claim yourself
Tap a source card that looks most relevant — a reputable news site, university, or government page is generally more reliable than an unknown blog. The link opens the original article in a new tab. Scan the opening paragraph and look for whether the article actually says what the viral claim says. Check three things: (1) Does the article mention the same fact the claim mentioned? (2) Does it use words like "study," "research," or "report" — or does it just quote someone online? (3) Is the article recent, or is it from years ago being shared out of context? If the source is behind a paywall, you will see a partial preview — scroll to see what you can, then move to a second source.
You'll know it worked when you can read at least the headline and opening paragraph of the original source and compare it directly to the claim you typed in Step 2.
Ask a follow-up question if the answer is unclear
Perplexity lets you keep asking in the same conversation. If you opened a source and it raised more questions — "Is this from a real university?" "Is this the only study?" — type a follow-up directly below the answer. Perplexity treats this as a continuing thread, so it remembers what you already asked. You can push deeper without retyping the whole claim. This is especially useful when a claim is vague or when you want to check multiple angles.
You'll know it worked when your follow-up question appears as a new bubble in the conversation and Perplexity generates a fresh answer with new sources below it.
- Only reading Perplexity's summary, not the sources. The AI summary is helpful but it is still an AI paraphrase. Always click at least one source card to read what the original article actually says — that is where the real fact-checking happens.
- Taking a single source as proof. One article does not make a fact. If you find only one site making a claim and every other source is silent, treat that claim as unconfirmed rather than verified.
- Searching with an emotionally charged version of the claim. If you type "XYZ company caught stealing user data!" the search may return opinion articles and outrage posts. Try a neutral version instead: "XYZ company data collection 2024." This surfaces factual reporting rather than reaction posts.
Go to perplexity.ai, paste one claim from your group chat or social feed, and click through to at least one source. Read the headline and opening paragraph. Ask yourself: does the original article actually say what the viral post said it said?
