# Fact Checker

> Use this tool when you need to verify the accuracy of claims or information by searching the web for evidence. It solves problems of misinformation and uncertainty by providing source citations and a verdict on the claim's validity. The Fact Checker takes in a claim as input and returns a verdict along with source citations as output, making it ideal for use cases where credibility and truthfulness are crucial.
