Vectara
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 retain context across conversation turns. Retrieval combines document extraction, neural and lexical search, knowledge reranking, and customized generation. The platform supports source citations, hybrid search, result reranking, and a RAG workflow builder; individual files can be up to 10 MB. Vectara says generated answers and actions receive a factual consistency score and advanced tool validation. Guardian Agents add real-time grounding, hallucination scoring, correction, and observability. Document sources include S3, Google Drive, SharePoint, Box, the web, Confluence, and SCIM; messaging connectors include Slack, Google Chat, and Zoom Contact Center. REST APIs are available at api.vectara.io/v2 with API-key or OAuth 2.0 authentication. Deployment choices are SaaS, a customer VPC, or on premises. Vectara says it does not train models on customer data and is SOC-2 Type II and HIPAA certified.
