Google's Stitch platform has been upgraded to an AI-native design platform, introducing the "vibe design" concept; Figma's stock price fell 8% in response.

According to 1M AI News , Google Labs yesterday upgraded its AI design tool Stitch to a full-featured AI-native software design canvas, officially introducing the concept of "vibe design." This involves describing design intent in natural language and having AI generate high-fidelity UIs, corresponding to the design side of vibe coding. The new version features four core updates:

- AI-native infinite canvas: Images, text, and code can all be dragged in as context, supporting real-time voice editing.
- Redesigned Agent and Agent Manager: Enables full-process inference across projects, supports parallel exploration in multiple directions, and tracks progress.
- DESIGN.md: A plain text design specification file, readable and writable by both humans and AI agents, analogous to AGENTS.md in programming. It is used for importing and exporting design rules across tools and also supports extracting design systems from any URL.
- One-click generation of interactive prototypes: Click "Play" to preview the application flow, and the Agent automatically infers the next logical page.

Stitch is now available to users aged 18 and older in regions where Gemini is available. It supports access to AI Studio via MCP servers and provides an official SDK, targeting both professional designers and entrepreneurs with no design experience. Following the announcement, Figma, a UI design platform, saw its stock price drop by 8%.
