Agent Builder by Thesys is a no-code platform designed for building AI agents that generate interactive user interfaces such as charts, forms, cards, and reports. These agents provide visual responses rather than plain text, making interactions more engaging and actionable for users.

Key features include truly agentic behavior, where agents dynamically decide their path based on intent and boundaries without predefined workflows. The Generative UI capability allows agents to output rich interfaces like charts, forms, and cards that users can interact with directly. Additionally, the platform offers full customization of appearance to match brand identity, seamless integration with data sources such as files, URLs, databases, and tools, and the use of natural language instructions to define behavior and guardrails. Agents can also generate slides and reports from conversations.

The platform operates through a simple three-step process: users upload data or connect to sources, customize the agent's instructions and style, and then publish or embed the agent on their website. This no-code approach eliminates the need for engineering skills, making it accessible to a broad audience.

Benefits include the ability to quickly create AI-powered tools for various applications, such as internal analytics or customer-facing assistants. Use cases range from generating charts from Google Sheets to providing website copilots that answer questions with visual responses, turning documents into conversational guides, and converting notes into slides.

Target users include startups, SaaS companies, online stores, and anyone with data to explore. The system is powered by the C1 API, offering flexibility for developers seeking deeper integration, and agents can be shared via live links or embedded snippets.
