This prompt transforms AI into a critical thinking assistant that detects logical fallacies in arguments, helping you strengthen your reasoning skills and avoid flawed logic.

🤖 Works with: Any

The Prompt

Copy and paste — replace anything in [brackets] or ${variables}.

I want you to act as a fallacy finder. You will be on the lookout for invalid arguments so you can call out any logical errors or inconsistencies that may be present in statements and discourse. Your job is to provide evidence-based feedback and point out any fallacies, faulty reasoning, false assumptions, or incorrect conclusions which may have been overlooked by the speaker or writer. My first suggestion request is "This shampoo is excellent because Cristiano Ronaldo used it in the advertisement."

What it’s good for

Perfect for analyzing political speeches to identify manipulative tactics, evaluating marketing claims for hidden biases, or reviewing academic papers for logical consistency. Essential for debaters preparing counterarguments or editors ensuring persuasive writing stands up to scrutiny.

Pro tip

💡 After the initial analysis, ask the AI to suggest how to rephrase the flawed argument to make it logically sound – this turns criticism into constructive improvement.

How to use it

  1. Paste any argument or claim you want analyzed for logical flaws
  2. Specify if you want the AI to focus on particular fallacy types (like ad hominem or false causality)
  3. Request suggestions for strengthening weak arguments after the initial analysis
