This ChatGPT Prompt Can Fact-Check Anything In Seconds

We’re drowning in opinions.

Tweets pretending to be facts. 

WhatsApp forwards that sound like news. 

Articles sprinkled with half-truths.

The internet gave everyone a megaphone. 

But it forgot to give us a lie detector.

That’s where this prompt comes in.

It’s a straight-up fact-checking machine you can drop into ChatGPT. 

Built to call BS on any claim fast, loud, and with receipts.

The Problem

Let’s be real. Most people don’t fact-check.

Not because they don’t care but because it’s a pain.

You’ve got to extract the claim.

Find a credible source.

Decide if it supports or contradicts the statement.

Then do that 10 more times.

Who’s got the time?

This prompt does it all. Automatically.

What This Prompt Actually Does

You give it a paragraph. A viral post. A sketchy stat from a PowerPoint.

It reads it.

It pulls out the core claims.

It hits the web.

It checks every line against credible sources.

And then it labels them:

• [TRUE] — backed by solid evidence.
• [FALSE] — straight-up wrong.
• [MIXED] — some parts check out, others don’t.
• [UNVERIFIABLE] — can’t confirm or deny.

Then it breaks it all down with links and reasoning.

Like a digital detective that never sleeps.

Who This Is For

This isn’t just for AI nerds or fact-checkers in a newsroom.

This is for journalists who want to avoid corrections after publishing.

Students and researchers who can’t afford bad citations.

Writers who want to build trust with every sentence.

Everyday users who want to know if that Facebook post is garbage or gold.

It works for anyone who values truth more than likes.

How It Works 

Here’s how it rolls:

1. You paste the text you want fact-checked.
2. The prompt extracts every key claim.
3. It searches credible sources online in real time.
4. Each claim gets rated and explained.
5. At the end, you get a summary of the overall reliability.

It’s like hiring an entire research team… for free.

Why It Works (and Doesn’t Just Guess)

Let’s get this straight: this isn’t just another summariser or chatbot with vibes.

This thing is wired to be skeptical.

It’s trained to think like a lawyer, not a cheerleader.

Here’s why it hits different:

• Critical thinking baked in: It doesn’t just believe what it sees. It analyses, doubts, questions.
• Real-time search: Uses the latest credible sources, not outdated internet noise.
• Source prioritization: Government data, academic research, and legit news only.
• Transparent logic: Tells you why it made a call. No hand-wavy nonsense.

This isn’t “I think.”

It’s “Here’s the evidence.”

You don’t need a plugin.

You just need ChatGPT.

Just copy paste this entire prompt in ChatGPT or create a custom GPT to start talking to your fact-checking AI.

<System>
You are a critical-thinking AI tasked with fact-checking any written content using both internal knowledge and real-time web search. You are highly analytical, deeply skeptical of unverified claims, and prioritize evidence-based reasoning.
</System>

<Context>
The user has provided a paragraph, article, or set of statements they wish to verify. You are to evaluate the accuracy and credibility of the content.
</Context>

<Instructions>
1. Extract the main claims or factual assertions from the input text.
2. Use the web search tool to find up-to-date, credible sources that support or contradict each claim.
3. Evaluate each claim individually, labeling them as:
   - **[TRUE]** (supported by credible evidence),
   - **[FALSE]** (contradicted by evidence),
   - **[MIXED]** (partially supported or ambiguous),
   - **[UNVERIFIABLE]** (insufficient data or speculative).
4. For each claim, provide:
   - A short summary of what the claim says.
   - Your search results and citations.
   - A justification for your truth rating using reasoning and references.
5. Conclude with a brief summary of the article's overall factual reliability (**High**, **Moderate**, **Low**).
</Instructions>

<Constraints>
- Use only reputable sources (news outlets, government data, academic publications).
- Avoid opinionated or fringe sources unless no alternative exists.
- Cite all sources used in markdown format with clickable links.
- Do not assume claims are true unless verified.
</Constraints>

<Output Format>
**Fact-Checking Report**

---

**Claim**: [Extracted claim]  
**Rating**: [TRUE/FALSE/MIXED/UNVERIFIABLE]  
**Justification**: [Clear explanation with citations]  

---

(Repeat for each claim)

---

**Overall Assessment**  
**Reliability**: [High/Moderate/Low]  
**Summary**: [One-paragraph explanation summarizing the reliability of the entire input.]
</Output Format>

<Reasoning>
Apply Theory of Mind to analyze the user's request, considering both logical intent and emotional undertones. Use Strategic Chain-of-Thought and System 2 Thinking to provide evidence-based, nuanced responses that balance depth with clarity. 
</Reasoning>

<User Input>
Reply with: "Please enter your article or claim to be fact-checked and I will begin the analysis," then wait for the user to provide their content.
</User Input>

That’s it.

Within 30 seconds, you’ve got a second brain that never lets a lie slide past.

Use it when:

• Writing blog posts.
• Reviewing your research paper.
• Reading political claims online.
• Debunking that annoying cousin’s conspiracy rant.

If you write, read, post, share or just don’t want to be misled this is your new default.

Truth Is Leverage

Everyone’s chasing attention.

Very few are chasing truth.

But trust beats traffic in the long game.

If your content is reliable, people come back. 

If it’s riddled with errors, they bounce and worse, they call you out.

This prompt gives you leverage.

It’s fast. It’s simple. It’s brutally honest.
