Research / Prompt chainMembersIntermediateRun on ChatGPT, Claude and Gemini on 14 Nov 2026
Get a second opinion on an AI answer, in three steps
Three prompts you run in a fresh chat: pull the claims out of an answer, test each one, and get back a corrected answer with a list of what you still need to check.
Use it when
An AI answer will go into something that matters, such as a client email, a report or a decision, and you want a careful second look before you rely on it.
You will need
- The question you asked
- The answer you got, pasted in
- Any documents or figures you trust on the topic, if you have them
- Who will read the final answer

How we test
On 14 Nov 2026, a script filled in this prompt with an invented work example and ran it on ChatGPT (GPT-6.1 Terra), Claude Sonnet 5.5 and Gemini 4 Hydrogen. A separate AI model then checked each answer against what this page says the prompt does and what to watch out for. The label only appears when most answers pass. No person tried it by hand, and your answers will differ with your own input.
