Lenz

Lenz is an innovative API designed for AI-driven products that require rigorous fact-checking to avoid hallucinations and misinformation. Unlike traditional models that produce single-shot guesses based on memory, Lenz extracts verifiable claims from any text, then cross-checks each assertion through independent sources, multi-model debates, and a review panel, providing a transparent verdict with sources, arguments, and process steps visible. This multi-model approach ensures comprehensive coverage and reduces blind spots, making it ideal for applications where accuracy and trustworthiness are critical. Available as an API and MCP, Lenz empowers developers to integrate robust fact-checking directly into their AI workflows, enhancing reliability and credibility in AI outputs.
