Lenz Fact-Check

Fact-check factual claims against independent sources. assess gives a fast multi-model verdict (True → False) with bucketed confidence in ~5–10s; verify runs a deeper research → debate → panel investigation for high-stakes claims and returns sourced, pollable results. ask answers grounded follow-ups on a completed verification. Verdicts are directional, not absolute. Connect via OAuth or a free Lenz API key.
