What is Lenz?
Lenz is a fact-checking tool that researches any claim across multiple independent sources and scores its truthfulness on a scale of 1–10. You get a clear conclusion with cited evidence — not just links to sort through yourself.
How does it work?
Each claim goes through a five-step pipeline: framing, research, debate (two AI models argue opposing sides), expert review (three more models score the evidence independently), and a final conclusion. The whole process typically takes about a minute or two.
What can I fact-check?
Anything — news headlines, social media posts, things a friend told you, health advice, historical claims, or anything you’re not sure about. Just paste the claim and Lenz does the rest.
Is Lenz free?
Yes — you get 10 free claim verifications per month, no credit card required. If you need more, paid plans start at $7.99/month.
