One wrong fact can undo a thousand right ones.
Verify any claim in seconds — before it goes live.
A single unverified stat in an article. A questionable claim in a presentation. A “fact” in a social post that turns out to be false. The consequences — retractions, corrections, lost credibility, social media pile-ons — far outweigh the seconds it takes to check.
Lenz is your verification shortcut. Paste any claim you’re about to publish. Get a sourced verdict in seconds. Move on with confidence.

- Paste it into Lenz — AI researches it across multiple real sources in seconds
- Publish with confidence — or rewrite the line. Either way, you know.
Why professionals trust the result
- Structured pipeline, not a chatbot opinion. Five automated stages — framing, research, debate, adjudication, conclusion — enforce citations and penalise unsupported claims.
