Real-Time Fact-Checking Agent · Live Web Verification
Verify claims, URLs, and AI-generated content against live web sources. Structured verdicts with confidence scores, sources, and exactly what changed.
Verdicts
Every verification returns one of four machine-readable verdicts — no essays, no vague citations. Just a clear answer your agent can act on.
Why VERITY
Existing tools either require human editors (days of lag), return raw search results (no verdict), or only work on subscription (can't scale for agents).
