Frequently asked questions

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 yes/no questions you’ve been wondering about. Open questions like "Who won X?" will give you answer choices to check. Just paste the claim or question 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.
