Lenz is a verification 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.
What kinds of claims can I check?
Anything factual — health and science claims, political
statements, viral posts, things AI told you, or common beliefs
you’ve never questioned. You can paste a claim directly or
submit a URL and Lenz will extract the claims for you.
Can I trust the results?
Every source is cited so you can verify the evidence yourself.
Multiple AI models from different providers cross-examine each
other — so no single model’s blind spots drive the
result. Human editors review every conclusion before
it’s published.
Why not just ask ChatGPT?
A chatbot gives you one model’s best guess from memory. Lenz
runs a structured multi-step process — research, debate,
adjudication — across multiple AI models from different
providers. Every source is independently retrieved and cited, and
human editors review every conclusion before it’s published.
Is Lenz free?
Yes — you get 20 free claim verifications per month, no credit card
required. If you need more, paid plans start at $7.99/month.
