Vectara
Vectara is a paid enterprise AI agent platform for building governed, grounded, and auditable agents.
What Vectara is
Vectara is a paid enterprise AI agent platform for building governed, grounded, and auditable agents. Agents can search company data, call external APIs, take actions, and keep context between conversation turns. Retrieval combines document extraction, neural and lexical search, knowledge reranking, and customized generation, with source citations, hybrid search, result reranking, and a RAG workflow builder. Vectara says generated answers and actions receive factual consistency scores and advanced tool validation. Guardian Agents add real-time grounding, hallucination scoring and correction, and observability. Sources include S3, Google Drive, SharePoint, Box, the web, Confluence, and SCIM; messaging connectors include Slack, Google Chat, and Zoom Contact Center. REST APIs use api.vectara.io/v2 with API keys or OAuth 2.0. Deployment can be SaaS, a customer VPC, or on premises. Maximum file size is 10 MB. Pricing is on request with a 30-day trial; listed annual plans start at $100,000 a year for SaaS, $250,000 a year for VPC, and $500,000 a year for on-prem.
