Google Fact Check Explorer

What it is

Fact Check Explorer is part of Google's Fact Check Tools. It searches a database of fact-check articles published by news organisations and independent fact-checkers in many countries and languages. Type a claim, a name or a topic, or search with an image, and it lists published fact checks with the publisher, the claim checked and the rating they gave.

Why it matters for AI trainer work

A large part of AI trainer work is checking whether a model's answer is true. Rubrics almost always include accuracy, and a confident, well-written answer with one false claim usually fails. Trainers who skip checking give high ratings to wrong answers, which is exactly the error quality reviewers look for.

Fact Check Explorer helps in two ways. For popular claims, such as health myths, viral statistics or quotes attributed to famous people, it shows you quickly whether professionals have already checked them. And reading a few fact checks teaches you how good checking works: find the original source, compare it with the claim, note what is missing or out of context.

Its limits

• It only covers claims someone has already fact-checked, mostly news and public-interest topics. Most technical, scientific or code claims will not be there.
• For those, go to primary sources: official documentation, standards, government statistics, the paper itself, or run the code.
• A fact check is a judgement by its publisher. Read the reasoning, not just the rating.

A simple checking routine

1. Underline every checkable claim in the answer: numbers, dates, names, quotes, causes.
2. Search for popular claims here first.
3. For everything else, find a primary or official source.
4. Note in your justification which claims you checked and where, as many rubrics ask for this.
5. Never check facts by asking another chatbot: that is not a source.

Best for: AI trainers and raters who need to verify claims in model responses, and anyone learning to fact-check.
