# Vectara

> Enterprise RAG platform for building trustworthy AI assistants.

Vectara is an enterprise-grade generative AI platform that provides retrieval-augmented generation (RAG) as a managed service — enabling companies to build accurate, grounded AI search and Q&A applications over their own documents without managing LLMs, vector databases, or complex retrieval pipelines. Its Boomerang embedding model and HHEM hallucination evaluation model are widely adopted by the AI community for their accuracy. Enterprise teams building internal knowledge assistants, customer-facing AI search, and document intelligence applications choose Vectara for its RAG accuracy, enterprise security controls, and the ability to deploy without deep ML infrastructure expertise.
