Google Stitch is an experimental AI tool launched by Google Labs at Google I/O 2025, designed to streamline UI design and frontend code generation for mobile and web apps. Powered by Google’s Gemini 2.5 Pro and Gemini 2.5 Flash models, Stitch transforms natural language prompts or image inputs into high-quality UI designs and functional HTML/CSS code, enabling rapid prototyping. It integrates seamlessly with tools like Figma, catering to both beginners and professionals.
Core Features
- Natural Language UI Generation: Create UI designs and code from simple English prompts (e.g., “a blue-themed photo-sharing app”).
- Image Input Support: Upload sketches, screenshots, or whiteboard designs to generate digital UI interfaces.
- Code Export: Produces development-ready HTML/CSS code, compatible with environments like CodeSandbox and VS Code.
- Figma Integration: Export designs directly to Figma for further refinement and collaboration.
- Multi-Variant Generation: Generates multiple UI variants for experimenting with layouts and styles.
- Customization Options: Offers theme selectors, color, and font adjustments for interactive design refinement.
Features and Advantages
- Efficiency: Reduces UI design and coding time from hours to minutes, with internal tests showing an 84% time reduction for page creation.
- Ease of Use: Accessible to users without deep design or coding expertise, ideal for beginners.
- Multimodal Input: Supports both text and image inputs, catering to diverse user needs.
- High-Quality Output: Generated code achieves a Lighthouse accessibility score of 98.6%, surpassing industry averages.
- Iterative Support: Enables continuous design refinement via AI chat and screenshot annotations.
- Free Access: Available for free in public beta with monthly generation limits (350 for Flash mode, 50 for Experimental mode).
Use Cases
- Startups: Rapidly create UI prototypes for minimum viable products (MVPs).
- Developers: Accelerate UI design iterations and shorten concept-to-code cycles.
- Designers: Generate multiple design variants and refine them in Figma.
- Non-Technical Users: Create professional-grade UIs without design or coding skills.
- Education & Learning: Enable students or beginners to practice UI design and development.
Supported Platforms
- Web: Accessible via stitch.withgoogle.com, browser-based, no installation required.
- Mobile: Supports UI design generation for mobile apps.
- Integrated Tools: Compatible with Figma, CodeSandbox, VS Code, and other design/development environments.
