Fact-check a claim before you trust it

Works with ChatGPT · Claude · Copilot

What you’ll be able to do

You can pressure-test a claim and find out how you could verify it yourself.

The problem

AI can state wrong facts as confidently as right ones.

What this skill does

Ask AI how to check a claim and what would prove it false.

When to use it

  • Before repeating or acting on a factual claim.
Juni, the One AI Skill guide

Juni’s tip

Do not ask if it is true. Ask how you would check.

The prompt

For this claim, tell me how confident you are, how I could verify it, and what would prove it wrong. Claim: [paste claim]

Weak vs. better

✗ Weak prompt

Is this true?

✓ Better prompt

Assess the claim below: your confidence, two ways I could verify it independently, and what evidence would disprove it. Claim: [paste claim]

Why this works

Asking how to verify and how to disprove turns a yes/no into a check you can actually run.

Practice task

Try it now

Take a claim you are unsure about and ask how to verify it.

Self-check

  • You get concrete ways to verify, not just a yes
  • It states what would prove the claim wrong

Common mistakes to avoid

  • Treating the AI answer itself as the proof.
  • Accepting one source instead of checking independently.
