Agent Builder by Thesys is a no-code platform designed to create AI agents that produce interactive user interfaces such as charts, cards, forms, and reports. The main purpose is to enable users to build and deploy AI applications quickly without any coding required, allowing for easy sharing or embedding on websites.

Key features include the ability to create truly agentic systems where agents reason dynamically based on defined intent and boundaries, eliminating the need for predefined workflows. The Generative UI capability allows agents to respond with rich, interactive elements like charts and forms instead of plain text. Additional features include full customization of the agent's appearance to match brand identity, seamless integration with various data sources such as files, URLs, databases, and tools, and control over agent behavior through simple natural language instructions. Agents can also generate AI-powered slides and reports from conversations.

The unique approach involves defining the agent's goals and constraints, after which the agent autonomously determines the best path to achieve outcomes, leveraging the Generative UI API to create real-time, interactive interfaces.

Benefits include the ability to turn conversations into actionable interfaces, suitable for use cases like generating charts from data, answering customer questions on websites, converting documents into interactive guides, and creating presentations from notes. This enhances user engagement and productivity.

Target users range from startups and SaaS companies to online stores and individuals with data to explore. The platform integrates with various tools and is powered by the C1 API, offering flexibility for both no-code and code-based customization.
