You asked “is this actually true?” — here’s how Lenz finds out. Your claim is researched across multiple independent sources, scored for truthfulness, checked for bias, and backed by real evidence you can verify yourself.
Every claim passes through six steps designed to be thorough, transparent, and impartial. Here’s what happens behind the scenes.
-
Step 1
Claim framing
Your claim is received and cleaned up. We strip away emotional language and bias, distill the core factual statement, and prepare targeted search queries — so the rest of the process starts from a neutral, testable hypothesis.
-
Step 2
Research
We search the web in parallel using multiple queries, collecting diverse, high-quality sources. Each source is scored for authority, recency, and relevance, and tagged as supporting, refuting, or neutral — building a balanced research brief.
-
Step 3
The arguments
We use two separate AI models to argue opposing sides in two rounds. First, one builds the strongest case that the claim is true while the other constructs the most compelling argument against it. Then each reads the opponent’s argument and writes a targeted rebuttal, exposing weak points in reasoning or evidence. Both draw exclusively from the collected evidence, ensuring every angle is stress-tested before the conclusion is reached.
-
Step 4
Expert review
Three separate AI models — each evaluating a different axis — independently review the evidence and debate arguments. One audits source reliability and independence, another examines whether the evidence logically supports the claim, and a third checks for missing context or misleading framing. Each scores the claim and explains its reasoning.
-
Step 5
The conclusion
All debates and analyses are synthesized into a single clear conclusion — True, Mostly True, Misleading, or False — with an Lenz Score from 1 to 10. A concise summary explains where the reviewers agreed or disagreed, and surfaces any important bias or logic warnings.
-
Step 6
Human verification
When you mark a claim as publicly accessible, it becomes eligible for review by a human editor on our team. An editor independently checks the automated analysis — reviewing the sources, reasoning, and conclusion — and confirms whether the report meets our quality and accuracy standards. Claims that have passed this review are clearly marked as human-verified on their claim page, giving you an extra layer of confidence in the result.
Talking to an expert
Still curious? Once the analysis is complete, you can chat with a specialized AI that deeply understands the specific claim and the concepts around it. It draws on the full research brief, debate arguments, expert reviews — and can pull in additional sources on the fly — so you get grounded, nuanced answers to your follow-up questions.
