Thesys
Generative UI foundation enabling AI apps to respond with interactive visual components.
About Thesys
Thesys is a generative UI platform that augments large language models (LLMs) to respond with interactive visual components like charts, dashboards, cards, slides, and reports instead of plain text. The platform consists of C1, a logic-aware API that generates UI elements in real-time, and Crayon SDK, a React library that bridges generation and deployment. It integrates with any LLM, framework, or MCP with minimal code integration. The tool is designed for teams building AI products that need to go beyond text-based responses. One limitation is that it requires integration with existing LLM infrastructure and developer expertise to implement effectively.
