Google has unveiled at I/O 2026 an update to Stitch, its interface design tool in Google Labs. The new feature is Stitch Agent, an assistant that allows real-time design while the user speaks or types. Ideas are transformed into interface components that are instantly built on the canvas, turning prototyping into a direct conversation with the machine.
How real-time conversational prototyping works 🎙️
Stitch Agent operates as a conversational prototyping environment. You describe what you need with voice or text, and the agent builds it as you watch. You can adjust colors, sizes, or flows with additional instructions without touching the mouse. The system interprets natural language and translates it into functional UI elements. There are no predefined templates; each component is generated from scratch based on your prompts, allowing rapid iterations and on-the-fly changes.

Finally, Google has understood that dragging squares for hours is a thing of the past. Now you can tell the computer: put a blue button here, but bigger, and make it look happy, and the agent does it. The downside is that if you have a strange accent, your interface might end up full of rounded corners you didn't ask for. But hey, at least you won't have to justify why you used Comic Sans.
