The “is this actually true?” question shows up multiple times a week — in a group chat, on a news headline, halfway through writing something you’re about to publish. Lenz is built for that exact moment: turn the question into a sourced answer you can check yourself, and share with confidence.
A receipt, not an opinion.
Why not just Google it or ask ChatGPT?
You can ask any chatbot whether something is true — and you’ll get a confident-sounding answer. The model draws on whatever it absorbed during training, with no obligation to check its own claims against real sources. When it doesn’t know, it guesses.
You can also Google it — and end up with five tabs open and your own opinion to form.
Lenz is built differently:
- Source-first, not memory-first. Every claim is checked against independently retrieved, scored, and cited sources. The evidence drives the conclusion — not the model’s prior beliefs.
- A panel, not a single voice. Multiple AI models from different providers evaluate each claim separately. Different training data, different blind spots — one model’s hallucination is another’s red flag.
- Engineered rigour at every step. The process doesn’t just “ask” a model for its opinion. Each stage — framing, research, debate, adjudication, conclusion — follows structured prompts that enforce citations, detect bias, and penalise unsupported assertions. Systematic by design, not by luck.
Real moments when Lenz helps
-
“Before you forward it”
Group chat. Slack. Family WhatsApp. Someone drops a shocking headline and asks “did you see this?” Three replies in, your name is on the chain. Paste the claim into Lenz before you forward — you’ll know in seconds whether it holds up, and you can send the verdict back instead of the rumor.
-
“I don’t trust either side on this”
A polarising claim where both sides are spinning hard. You don’t want a partisan take — you want the sources, the evidence, and a straight answer. Lenz checks claims against independently retrieved sources, not talking points. The disagreement, when it exists, is part of the answer.
-
“Should I actually worry about this?”
Coffee causes cancer. A new study just changed everything about diet. A supplement will fix your kid’s sleep. Health and science claims travel fast and hit hard. Before you panic or dismiss, get a sourced breakdown that’s honest about what the evidence actually shows — including where it’s mixed.
-
“Before you cite it”
A study finding for a research paper. A statistic for an article you’re writing. A claim from a textbook your kid is studying. Lenz researches the claim across multiple independent sources and gives you a sourced verdict with the references you can use directly in your bibliography or footnotes. The cited evidence is the actual scholarship — Lenz is the assistant that found it.
Next time you’re not sure — don’t scroll past it, don’t paste it into ChatGPT and hope. Verify it. Lenz shows the sources, shows the work, and you decide what to make of the answer.
And it really is hope: in our research on 1,000 real-world fact-checks, the five top frontier LLMs disagree on 67% of them.
