How can I fact-check an article before citing it?

You are about to cite or share an article and want a quick pass over its assertions first.

Fact-check identifies the checkable claims in a selection or a page and lays them out for verification. It is a pre-flight check, not a verdict: treat the output as a checklist of assertions that deserve a source. Claims that are matters of opinion or prediction are marked as such rather than falsely scored.

Select the passage, or capture the page and run fact-check on the capture, then work through the claims with your own sources. Researchers and students use it on dense articles before citing them.
