The deficit dropped by $1.4 trillion last year.
- The deficit— Defined entity
- $1.4 trillion— Precise number
- last year— Bounded timeframe
A few questions we often get.
AI hallucinates. How can you use it to fact-check?
We built our fact-checking platform to be search-first, not AI-first. We begin by finding authoritative sources about a claim and only then summarize the results. Every fact-check includes a full list of direct sources as supporting evidence, so reviewers can click through and verify the information themselves.
What is a trusted source?
We prioritize the most authoritative sources available for each claim, including official government websites, peer-reviewed journals, major research institutions, and established media outlets. All sources we use are provided so you can review them directly.
How do you decide what is "accurate"?
We don’t. Instead, we look for information from authoritative sources and summarize what we find, helping you understand whether a claim has supporting evidence or not. The accuracy score simply reflects how closely the claim matches the sources we found.
