Catch the Mistake

Use this to practice noticing errors. It writes a short paragraph with one hidden mistake, gives hints and shows how to check it afterward.

Works inChatGPTClaudeGemini

Write a short paragraph of about 80 words about [TOPIC] that contains one mistake. Do not tell me where it is. I will try to find it. If I am stuck, give me a hint. Then show me the mistake and how I could have checked it with a book or a trusted site. Make it a fair challenge for a [AGE]-year-old.

Tip: Look up the true fact together in a book or encyclopedia.

What to fill in

Before you send it, replace the parts in [square brackets] with your own details:

  • Topic
  • Age

If the AI gets it wrong

If it hides no mistake or more than one, that is a lesson too. Ask it to try again and compare.
