What does tambo do?

Tambo is an open-source AI orchestration framework specifically designed for React developers. It provides a complete toolkit for integrating intelligent assistants directly into your front-end applications. The framework handles streaming AI-generated UI components, manages conversation history, and provides state management hooks that connect user inputs directly to AI models. This means you can build interfaces where AI doesn't just respond with text, but can generate and update React components in real-time.

The framework stands out with its comprehensive feature set including automatic message thread storage, suggested actions that guide users through app functionality, and tool calling capabilities that let your AI assistant execute custom functions. It includes built-in authentication and supports the Model Context Protocol (MCP) for seamless integration with various AI models and tools. Everything streams in real-time, creating a responsive experience where users see UI components appear and update as the AI generates them.

Tambo is ideal for React developers building applications that need intelligent assistants, whether for customer support, internal tools, or creative applications. Use cases include building AI-powered help centers, creating guided onboarding experiences, developing intelligent form builders, or adding contextual assistance to complex applications. It's particularly valuable for teams that want AI capabilities without rebuilding their entire front-end architecture.
