How it works
- Paste a claim — anything from a headline to a bar-debate hot take
- AI researches & debates — multiple models check real sources, argue both sides, and cross-examine the evidence
- Get a sourced verdict — a truthfulness score from 1–10, a conclusion label, and every source cited
What makes Lenz different
- Multi-model debate pipeline. Claims pass through Framing, Research, Debate, Adjudication (3 models in parallel), and Conclusion — not a single prompt.
- Real sources, always cited. Every verdict links back to the evidence it relied on. No hallucinated references.
- Transparent scoring. You see the reasoning, the dissents, and the confidence level — not just a label.
- Follow-up questions. Ask the AI to dig deeper into any part of the analysis with grounded, source-aware chat.
