Introducing A2UI: An open project for agent-driven interfaces

An open protocol that lets AI agents return interfaces instead of text - safely, because the client only renders known components.

In short The foundation of the AI assistant on this website.

What it is about

A2UI is an open protocol from Google: an AI agent describes an interface as structured data, and the application renders it with its own known components.

What caught our attention

The security idea: the agent delivers no executable code, it only picks from an approved catalogue. Design, accessibility and security stay with the application - and the agent can still do more than text.

What we take from it

The AI assistant in the hero of this website is built on A2UI: answers arrive as tiles you can open and explore, rendered from our own component catalogue. Try it on the home page.
