What you will get

Every factual claim from the answer, each marked likely correct, uncertain or likely wrong with a reason, notes on anything missing or overconfident, and what to verify before you use it.

Why it works

AI answers can sound confident while being wrong, so the prompt breaks the answer into individual claims and rates each one. Asking for reasons shows why something is doubtful. Listing what to verify turns the review into a short checklist, and the tip is the key point: important facts need a trusted source.

Common mistake

You treat the checker’s verdict as proof.

Fix: It is a second opinion from the same kind of tool. Verify important claims in a trusted source, as the tip says.

Also watch for

The original question is left out. Paste the question too. An answer can be correct but still miss what you asked.
Numbers and quotes slip through. Ask for every number, name, date and quote as its own claim, since these are the easiest to get wrong.

Try a variation: check a summary

Paste a source document and an AI summary of it, and ask which sentences in the summary are not supported by the source.

Put the uncertain and likely wrong claims in a table with what kind of source could confirm each one and what to search for.
