Description
Lenz is an AI fact-checking API for products that cannot afford to hallucinate. It extracts verifiable claims from any text, then checks each one: searching independent sources, running multi-model debate, and routing through a review panel — returning a scored verdict with every source, argument, and step visible. Most AI tools give you one model's best guess from memory. Lenz ensures no single model's blind spots drive the conclusion. Available as API and MCP. Try it free at lenz.io/ph

Could you build this?
Yes It is an LLM agent orchestration pipeline that decomposes text into claims, queries existing search APIs (e.g., Tavily or Serper), and prompts models to deliberate and score verification results.
