Fact-Checking
Cross-reference claims against multiple independent sources in real time and read verdicts with evidence.
How fact-checking works
Fact-checking takes a claim — pasted in directly, or selected from an AI answer — and cross-references it across multiple independent sources in real time. Because AI Search already aggregates Wikipedia, news APIs, finance data, Brave Search, Diffbot and Exa, a claim is tested against genuinely separate corpora rather than echoes of one origin.
- 1
Submit a claim
Paste a statement, or highlight a sentence in any answer and choose Fact-check.
- 2
Sources are queried
The claim is decomposed into checkable assertions and each is searched across independent sources in parallel.
- 3
Read the verdict
Each assertion gets a verdict with the supporting or contradicting evidence linked beneath it.
Reading verdicts
Verdicts are graded, not binary — real claims are often partially true, outdated or unverifiable rather than simply right or wrong.
| Verdict | Meaning |
|---|---|
| Supported | Multiple independent sources agree with the claim |
| Contradicted | Independent sources state otherwise; the conflicting evidence is shown |
| Partially supported | Some assertions hold, others do not — each is broken out separately |
| Insufficient evidence | The connected sources do not contain enough to verify either way |
Best practices
Check one claim at a time
Short, specific statements verify more cleanly than long compound paragraphs.
Mind the date
Figures like stock prices and headcounts change. Verdicts note when evidence appears outdated.
Open the evidence
Every verdict links its sources — for high-stakes decisions, read the underlying material yourself.
Fact-checking reflects what the connected sources say at query time. "Insufficient evidence" means the sources are silent — not that the claim is false. Always apply judgment for consequential decisions.
