Chain of Verification for AI
Detect and eliminate hallucinations in any LLM output. Every factual claim extracted, searched, verified, and scored against your knowledge base.
AI Doesn't Know When It's Wrong
LLMs generate confident, fluent text — even when the facts are fabricated. Without verification, hallucinated claims reach customers, patients, and decision-makers. COVE catches every error before it causes damage.
