Vectara

What is Vectara?

Vectara is an agentic AI platform for building search, question answering and agents on top of company data. It ingests documents, images, tables, emails and tickets, indexes them for hybrid semantic and keyword retrieval, reranks results and generates answers grounded in the retrieved content, with hallucination detection and evaluations on responses. Its own models include Boomerang for retrieval and Mockingbird for RAG-tuned generation, and you can bring a model such as Claude, GPT or Gemini instead. Developers reach everything through a REST API, MCP and agent-to-agent interfaces, and the agent harness covers skills, tools, memory and sub-agent workflows. Vectara can run as SaaS, inside your VPC on AWS, Azure or GCP, or on-premises, with SSO, access controls and audit trails in each. A 30-day free trial includes 10,000 credits. Paid use is billed by usage bundles, with the Standard plan starting at a $100 monthly minimum, and VPC and on-prem pricing is quoted on request.

Use cases

• Build RAG chatbots over company data
• Answer questions with cited sources
• Add semantic search to apps and sites
• Create enterprise AI agents
• Search support tickets and technical docs

• Deploy retrieval inside a private VPC

Who it's for

• Developers
• Enterprise AI teams
• Support organizations
• Research teams

Why use Vectara

• Retrieval, reranking and generation come as one platform, so you do not assemble a vector database and embedding pipeline yourself.
• Grounded answers with hallucination checks suit use cases where wrong answers are costly, such as support and research.
• Deployment choices from SaaS to air-gapped let regulated teams keep data in their own environment.
• Usage-based bundles tie cost to queries, storage and generative requests rather than seats.
• Support for outside models avoids locking an application to one LLM.
