Lenz

Lenz is an AI fact-checking API designed for applications where hallucinations cannot be tolerated. It extracts verifiable claims from text, then validates each claim by searching independent sources, running multi-model debate, and routing through a review panel to return scored verdicts.

Unlike single-model approaches, Lenz uses multiple models to eliminate individual blind spots. Results include all sources, arguments, and reasoning steps. Available as an API and MCP (Model Context Protocol) integration.
