Google Stitch: Free AI Vibe Design Tool with Agent and Web Export

Google Stitch is a free AI UI design (vibe design) tool from Google Labs that turns natural language prompts, sketches, screenshots, existing design files, and codebase context into high-fidelity mobile and web app interfaces with exportable frontend code.

Google launched Stitch at Google I/O 2025 as an experimental AI design tool. After the March 2026 “vibe design” update added an AI-native canvas, voice input, prototypes, and DESIGN.md design systems, the Google I/O 2026 update pushed Stitch further toward live AI-assisted product design.

Stitch Agent can now stream work onto the canvas in real time, reflow layouts while you steer the direction, import existing design or code files, generate motion-focused UI, share work through Google AI Studio, export screens to Google Antigravity, and publish directly to the web with Netlify.

Describe an app screen, upload a sketch, import project context, or speak changes aloud, and Stitch builds multi-screen interfaces with consistent layouts, components, themes, and code. It is available in English for users 18 and older in regions where Gemini is supported.

Features

• Generates complete mobile and web UIs from natural language descriptions.
• Transforms hand-drawn sketches, wireframes, and screenshots into high-fidelity editable designs.
• Imports existing design files and codebase context so Stitch can work from assets your team already has.
• Streams generated work directly onto the canvas, so you can watch layouts appear and guide changes before the design is finished.
• Provides multiple layout variants for each prompt so you can compare directions before refining one version.
• Places generated screens on an AI-native infinite canvas that handles images, text, and code together.
• Includes Stitch Agent, which understands project context and helps manage parallel design explorations.
• Supports voice interaction for live design critiques, layout changes, and screen generation.
• Creates interactive prototypes by stitching screens together with clickable hotspots.
• Generates kinetic UI and motion graphics for higher fidelity product flows.
• Builds automatic design systems with DESIGN.md, an agent-friendly markdown file that documents and syncs design rules.
• Generates frontend code with responsive layouts.
• Offers one-click paste to Figma with editable layers and Auto Layout.
• Creates shareable links through Google AI Studio.
• Exports screens to Google Antigravity for backend logic and app development work.
• Publishes designs directly to a live web URL with Netlify.
• Connects with MCP servers, the Stitch SDK, and Stitch Skills for agent-based design and development workflows.

Use Cases

• Build investor-ready app prototypes from a product idea, sketch, or screen description.
• Import an existing design or codebase and ask Stitch Agent to explore a new product direction.
• Align teams during sprint planning by generating multiple layout directions on a single canvas.
• Create pitch mockups for clients during agency work without starting from a blank Figma file.
• Explore layout, color, and interaction variations before committing to a design direction.
• Test user journeys with clickable prototypes before writing production code.
• Generate motion-heavy UI concepts for onboarding, dashboards, landing pages, and product demos.
• Publish a prototype to a live URL through Netlify when a team needs a quick review link.

How to Use Google Stitch

1. Go to stitch.withgoogle.com and sign in with your Google account. Stitch is available in English for users 18 and older in supported Gemini regions.

2. Select either Mobile or Web app, and then pick a generation mode:

3. Write a clear description of what you want. A useful prompt includes:

• Context and platform, such as a mobile fitness app or web dashboard
• Core components, such as a navbar, cards, charts, bottom nav, or settings panel
• Visual style, such as a dark theme, green accents, compact density, or large editorial type
• Specific requirements, such as WCAG compliance, one-handed use, or a motion-based onboarding flow

Example prompt: “Design a mobile dashboard for a crypto tracking app. Include a top navigation bar with logo and notification bell, a portfolio summary card showing total value and percentage change, a pie chart for asset distribution, a horizontal scroll section for trending coins, a two-column grid for top movers, and a bottom navigation bar. Use a dark theme with green accent colors and rounded corners.”

4. You can also upload a sketch or screenshot, import existing design files, or bring codebase context into the canvas. Add a short instruction that explains what Stitch should preserve and what it should change.

5. Hit generate and watch the result appear on the canvas. With the real time Stitch Agent update, you can steer the direction while the design is still forming instead of waiting for a finished draft before giving feedback.

6. The infinite canvas lets you work across multiple ideas at the same time. You can:

• Drag and resize components manually
• Adjust colors, typography, and spacing via the sidebar
• Add new screens and link them for prototyping
• Use multi-select to apply changes across screens
• Ask Stitch Agent to generate logical next screens based on clicks
• Generate more variations or regenerate the UI
• Add motion and animated states when a static screen is not enough

7. Use voice for live changes. Click the voice icon in the chatbox and speak directly to the canvas. Stitch Agent can critique the design, ask follow-up questions, and update screens while you talk.

8. Export or publish your UI design:

• Figma: Click “Copy to Figma” and paste directly into your Figma file. Works in Standard Mode only.
• Code: Click on the generated design, select the Code tab, and copy HTML/CSS or React code.
• Google AI Studio: Generate a shareable link or continue development in Google’s AI development environment.
• Google Antigravity: Export screens to Google’s agent-first development platform when you need to connect backend logic.
• Netlify: Publish your work from the canvas to a live web URL.
• MCP: Use the Stitch MCP server to connect with tools like Antigravity, Gemini CLI, Claude Code, or Cursor.
• ZIP: Download an archive with assets and code.

Pros

• Cuts early UI design time from hours or days to minutes.
• Non-designers can create polished UI concepts without deep Figma expertise.
• Generates both visual layouts and frontend code in one workflow.
• Real time steering makes iteration faster than waiting for complete design drafts.
• Import support helps teams refresh an existing design instead of starting from a blank prompt.
• Netlify publishing makes Stitch useful for quick prototype reviews outside the design tool itself.

Cons

• Works better for UI concepts and prototypes than production-ready full applications.
• Monthly quotas limit heavy daily use.
• English-only access limits teams that need multilingual design collaboration.
• Google Antigravity or another development tool is still needed for backend logic and full app behavior.
• Generated code still needs review before production use.
