About Thesys

What the tool does and who it's for

Thesys is a frontend infrastructure platform designed for AI-native products, specializing in Generative UI. Its flagship API, C1, transforms LLM responses from models like OpenAI and Anthropic into live, interactive interfaces such as charts, forms, and tables in real-time. By bypassing the need to hardcode every possible UI state, Thesys enables developers to build context-aware agents, copilots, and dashboards that adapt to user behavior. The platform includes a no-code Agent Builder for rapid prototyping and an SDK for seamless React integration.

C1 Artifacts API: Enables generation of complete slides and structured reports.
Enterprise Security: SOC 2 Type 2, GDPR, and ISO 27001 compliant with zero data retention.
