Google updates Stitch with voice input, infinite canvas, and a new design agent

Google Labs has pushed its biggest update to Stitch, its AI-powered UI design tool, adding voice control, an infinite canvas, and a redesigned agent that tracks a project across its entire history.

The company is also introducing a new term for the workflow: "vibe design."The concept isn't far from vibe coding. You describe what you want—the business goal, the feeling, the aesthetic—and Stitch builds a working interface. No wireframes, no handoffs. The tool generates editable design files and front-end code you can feed directly into a dev pipeline.

Stitch's new voice mode lets you request design changes, variations, and critiques out loud

The voice feature is the most tangible addition. You can ask for three different menu layouts, switch colour palettes, or have the agent interview you to build a landing page from scratch—all without typing.

The agent also offers real-time design critiques as you work.A new Agent Manager lets you run parallel design directions from a single canvas, useful when you're still exploring options before committing to one.

DESIGN.md makes it easier to carry a design system across multiple Stitch projects

Stitch now supports DESIGN.md, a markdown format that lets you extract a design system from any URL and import it into a new project. It's a practical addition for anyone who has had to rebuild the same component library twice.

On the integration side, the tool connects to Claude Code, Cursor, and Antigravity via an MCP server and SDK. You can also extract design context directly into AI Studio.Stitch is still sitting inside Google Labs and isn't widely available. But the update is a clear signal that Google is pushing the tool well beyond a simple prototyping aid.
