Google Labs interface-design canvas
To start a screen, state the business goal and the feeling you want users to have, then place reference images or existing code on the infinite canvas. The design agent reasons over how the project has already evolved, and the agent manager keeps parallel ideas separate. Rules can be written as DESIGN.md or extracted from a URL and applied to the next project. A static screen can become a clickable prototype: link the screens, press play, and the system can add the next screen from a click. Voice can ask for a new palette or several menu options. Finished work can go to developer tools through MCP and the SDK. It fits designers and founders who want to try interfaces quickly and share one set of rules with development.
Stitch is a Google Labs interface-design canvas. It turns natural language, images, text, or code into high-fidelity UI and on into clickable prototypes. An infinite canvas holds several directions at once. A design agent reasons over how the project has evolved, and an agent manager tracks parallel ideas. Design rules can be saved as DESIGN.md or extracted from a URL, then imported or exported to other projects and tools. Screens can be linked and played as a flow, and voice can ask the canvas to change palettes or menus. Designs can also move to developer tools such as AI Studio and Antigravity through the MCP server and SDK.
Difficulty: Intermediate
Infinite canvas for context
Images, text, and code can sit on the infinite canvas as context from early ideas through a working prototype.
A design agent for parallel ideas
The design agent reasons across the project's evolution, and the agent manager tracks progress on several ideas at once.
Exchange rules as DESIGN.md
A design system can be extracted from a URL, or moved in and out as DESIGN.md so the next project or tool can reuse it.
Playable screen flows
Static screens can be linked and played, the path previewed by clicking, and a logical next screen generated from that click.
Voice edits and a handoff to code
Voice can request new palettes or menu options, and MCP plus the SDK can hand the design to AI Studio or Antigravity.
A founder tries a first interface
A founder describes the product goal in a paragraph, explores several screens on the canvas, then links them into a clickable flow.
A designer reuses a design system
A designer extracts a design system from an existing URL, or imports DESIGN.md, so a new project follows the same rules.
A design moves into developer tools
After the UI is settled, the Stitch MCP server and SDK pass the design to AI Studio or Antigravity for implementation.
Google Labs says to start from the business goal, the feeling you want users to have, or examples you are looking at, rather than from a wireframe. Those notes, plus images, text, and code, can go on the infinite canvas. The design agent reasons over what the project already contains. To try several directions, use the agent manager so the ideas stay separate.
DESIGN.md can import or export design rules, and a design system can be extracted from a URL and applied to another Stitch project. Screens can be linked and played to check the path. For development, the post names the MCP server and SDK, with export to AI Studio or Antigravity. It does not list every other developer tool.
