Vectara

Vectara is an enterprise agent platform that turns complex, multimodal data into trusted answers. It powers intelligent, managed AI agents with agentic RAG, multimodal retrieval, orchestration, and always-on governance, so enterprises can run grounded, secure, auditable agents with real-time policy and factual-consistency enforcement.
