Fact-check an AI answer in five minutes before you use it

Step 1: Ask it to list its own claims

After you get an answer, send this:

List every factual claim in your answer as a numbered list:
names, numbers, dates, prices, laws, and quotes. Next to
each one, say how sure you are and where I could check it.

Now you have a checklist instead of a wall of text.

Step 2: Sort by "what if it's wrong?"

Go down the list and put each claim in one of three piles:

• Would cost money or cause trouble. Prices, deadlines, tax rules, legal steps, medical or safety advice. Check every one.
• Would be embarrassing. A wrong name, a wrong date, a quote from someone famous. Check before you publish or send.
• Background. General explanations you are only using to understand a topic. Skim, don't chase.

Step 3: Check it against something you can open

• Go to the source. The government website for a rule. The company's own page for a price. The actual contract for what it says.
• Click every link. AI tools sometimes cite pages that don't exist, or that say something different. If the page doesn't say it, the claim doesn't count.
• Search the exact words. Put a quote or a specific phrase in quotation marks on Google. A real quote usually shows up with a named source.
• Check the date. Prices, laws, and app menus change. Look for when the page was last updated.
• Get a second source for numbers. Two places that don't copy each other.

Red flags that mean "check this first"

• Very exact numbers with no source.
• A quote from a famous person.
• A law or rule cited by section number.
• "Experts say" with no names.
• A confident answer about something that happened in the last few weeks.

Using a second AI to help

You can paste the answer into a different chat tool and ask, "What in this is likely to be wrong?" It sometimes catches mistakes. It can also be wrong in the same way. Treat it as a helper that points at what to check, not as the final judge.

The five-minute routine

1. Ask for the claim list (1 minute).
2. Sort into three piles (1 minute).
3. Open sources for the risky pile (3 minutes).

If you can't confirm something that matters, take it out or ask a person who knows. "I couldn't confirm this" is a perfectly good reason to leave a line out.

Short close

List the claims, check the risky ones against a source you open, and click every link. If you can't confirm it, don't use it.
