Start with the mechanism
Three steps to keep in mind
- 1
Split the answer into claims
A polished paragraph may contain several independently checkable statements.
- 2
Find suitable evidence
Prefer primary, current, accessible sources that directly address each claim.
- 3
Classify support
Evidence can support, contradict, or remain insufficient for a conclusion.
Try it yourself
The lab isolates this mechanism with a small, transparent simulation. Everything runs locally in your browser.
Open “Check a claim”Keep these three ideas
Go deeper when you need it
Technical detailWhat the short version leaves out
Retrieval and tools can ground an answer, but they can also retrieve irrelevant material or be interpreted incorrectly.
Useful systems expose uncertainty, separate facts from hypotheses, and make sources easy to inspect.
