Vectara

Vectara is a RAG-as-a-Service platform that simplifies building grounded generative AI applications. Unlike frameworks that require you to build RAG yourself, Vectara provides a complete managed solution with data ingestion, semantic search, and grounded generation out of the box. Unique features include Boomerang (hybrid search), Mockingbird (low-latency query rewriting), and hallucination detection (HHEM) to ensure reliable outputs. Enterprise-grade with SOC 2 Type II, HIPAA, and GDPR compliance. API-first architecture integrates into any application. Supports documents, structured data, and APIs as data sources. Perfect for enterprises that need reliable, accurate AI search without building complex infrastructure. Free tier available for developers.
