About Lenz

Claim verification, for individuals and the AI products they use.

Lenz turns “is this actually true?” into a sourced, scored verdict you can check yourself. Every claim runs through a structured pipeline — framing, research, multi-model debate, adjudication, conclusion — with every source and score published. You don’t have to trust Lenz; you can verify the verification. See how it works →

Why we built this

Independent and principled. Truth verification shouldn’t be gatekept behind editorial boards or paywalls — it should be a tool everyone has, with every source and score in the open. That’s what we’re building. Read our mission →
