Google Upgrades Stitch With AI-Native Design Canvas and Design Agent

Google has updated its Stitch tool, repositioning it as an “AI-native software design canvas” that allows users to generate and iterate on interface designs using natural language, the company announced. The new version introduces an expanded canvas, a design agent and collaboration features aimed at turning ideas into interactive prototypes more quickly.

The update centers on a redesigned interface built around an infinite canvas that supports multiple forms of input, including text, images and code. Users can begin by describing goals, user experiences or references, and Stitch generates high-fidelity UI designs that can be refined in real time. The company said the goal is to help users move from early concepts to working prototypes within a single environment.

Google is also introducing a new design agent that can analyze the full project context and assist across different stages of development. Alongside it, an “Agent manager” allows users to explore multiple design directions at once while keeping projects organized.

The platform expands its design system capabilities with a feature called DESIGN.md, which lets users extract design rules from existing sources or reuse them across projects. This is intended to reduce repetitive work and maintain consistency when building new interfaces.

Stitch also adds tools for rapid iteration. Users can convert static layouts into interactive prototypes, connect screens into flows and preview user journeys instantly. The system can generate follow-up screens automatically based on interactions, allowing teams to test and adjust designs without leaving the canvas.

Voice input is another addition, enabling users to speak directly to the tool to request changes, generate variations or receive feedback. The system can respond in real time, offering critiques or updating designs based on spoken instructions.

The platform is designed to integrate with development workflows. Stitch can export designs to external tools and connect with other systems through its MCP server and SDK, allowing teams to carry designs into production environments.

Google said the update is aimed at both professional designers and non-specialists, with the goal of reducing the time between an idea and a functional interface.
