Cube is an AI-native analytics and universal semantic layer platform designed to help businesses deliver consistent, governed data to employees, applications, and autonomous AI agents. The software connects to data warehouses and databases to establish a centralized semantic model containing business metrics, dimensions, joins, and access policies. Its Analytics Chat interface allows users to ask questions in natural language and receive answers grounded in approved business definitions rather than unstructured database queries. AI-powered Workbooks combine SQL editing, visual exploration, and an intelligent assistant that helps analysts create and refine queries. Dashboard creation tools enable users to generate charts, reports, and interactive visualizations through conversational instructions. Cube's Model Context Protocol server connects governed analytics with AI assistants such as ChatGPT, Claude, Cursor, and custom autonomous agents. Its embedded analytics capabilities allow software companies to integrate dashboards, conversational analytics, and self-service reporting directly into their applications. Performance optimization features include query caching, pre-aggregations, and scalable data APIs, while governance controls enforce permissions and row-level security. Cube also provides REST, GraphQL, and SQL interfaces, integrations with major data platforms, and an open-source semantic layer foundation for organizations building modern business intelligence systems.
