About A2UI is a declarative UI protocol designed to enable AI agents to generate rich, interactive user interfaces that render natively across web, mobile, and desktop environments without executing arbitrary code. Instead of relying on text-only interactions or unsafe approaches like sending HTML or JavaScript, A2UI allows agents to communicate UI intent through structured JSON messages that describe components, layouts, and data bindings, which client applications then render using their own trusted, pre-approved components. This approach separates UI generation from UI execution, ensuring that interfaces are secure, consistent with the host application’s design system, and adaptable across platforms. It is designed to be LLM-friendly, using a flat, streaming JSON structure that allows agents to incrementally build and update interfaces in real time, enabling progressive rendering and responsive user experiences.		About Retool is an AI-powered platform that enables teams to build internal software, agents, and workflows faster using natural language and composable building blocks. It allows users to go from a simple prompt to a fully deployed application that works with their existing data, systems, and business rules. Retool connects seamlessly to databases, APIs, LLMs, and external tools to create production-ready applications. The platform supports building AI agents, dashboards, workflows, and full-stack internal apps with flexibility and control. Teams can design interfaces visually, customize logic with code, or generate components using AI assistance. Retool integrates with modern developer workflows, including version control, CI/CD, and testing. Overall, it helps organizations reduce development time while maintaining enterprise-grade security and reliability.
