Google Stitch: Free AI Tool That Turns Prompts into UI Designs
Building a side project but struggling with UI design? Google Stitch is an AI-powered tool that generates complete user interfaces from simple text prompts. Best part: it is completely free.
What is Google Stitch?
Google Stitch is an AI tool from Google Labs, launched at Google I/O 2025. It uses Gemini AI models to transform your descriptions into UI designs and exports clean, production-ready code.
Think of it as having a UI designer on demand. Describe what you want, upload a sketch, or share a screenshot - and Stitch builds it.
Try it: stitch.withgoogle.com
Key Features
Text-to-UI Generation
Describe your interface in plain English:
- "A pricing page with 3 tiers and a toggle for monthly/yearly"
- "A dashboard with sidebar navigation and data cards"
- "A login form with social auth buttons"
Stitch generates a complete, responsive design with multiple screens.
Image-to-UI
Have a screenshot, sketch, or wireframe? Upload it and Stitch recreates it as clean, editable code. The tool handles napkin sketches, whiteboard drawings, and polished mockups equally well.
Export Options
- AI Studio (Preview) - Export to Google AI Studio with HTML and images
- Jules - Send directly to Google's AI coding assistant to build your project
- .zip - Download as zip file containing HTML and image files
- Code to Clipboard - Copy code for pasting into coding agents like Lovable, Copilot, or Cursor
Four AI Modes
| Mode | Model | Best For |
|---|---|---|
| Fast | Gemini Flash | Quick iterations, export to code or Figma |
| 2.5 Pro | Gemini 2.5 Pro | High-quality HTML designs, export to coding agents |
| Thinking with 3 Pro | Gemini 3 Pro | Maximum quality and reasoning over speed |
| Redesign | Nano Banana Pro | Redesign existing apps/sites from screenshots |
Use Fast for quick exploration, 2.5 Pro or 3 Pro for polished designs, and Redesign to recreate existing interfaces.
Prototypes (New with Gemini 3)
Google recently upgraded Stitch with Gemini 3, introducing the ability to stitch together different screens on your canvas to create working prototypes. Instead of static screens, you can now design interactions and complete user flows.
Annotate Feature
The Annotate feature (marked with a banana icon, hinting at Google's Nano-Banana model) lets you add comments and visual notes directly onto UI screens. Submit your annotations, and Gemini AI processes the feedback to implement context-aware UI changes.
Multi-Select Editing
Hold Shift and click to select multiple screens at once. Apply a single prompt or theme change to all selected screens simultaneously - a huge time-saver for maintaining consistency.
How to Use Google Stitch
Step 1: Access the Tool
- Go to stitch.withgoogle.com
- Sign in with your Google account
- No installation needed - fully web-based
Note: You may need to join a waitlist, which typically approves access within a few hours.
Step 2: Describe Your UI
Write a clear prompt describing what you need:
Good prompt:
A mobile app onboarding screen with:
- Welcome headline
- 3 feature highlights with icons
- Get Started button at the bottom
- Progress dots showing step 1 of 3
Vague prompt (avoid):
Make a nice welcome page
Step 3: Refine and Iterate
- Use chat to make conversational edits
- Use Annotate to mark up specific areas for changes
- Generate multiple variants to explore different layouts
- Adjust themes and color palettes with a single prompt
Step 4: Export Code
Click Export and choose your format:
- HTML/CSS for vanilla projects
- Tailwind CSS for utility-first workflows
- JSX/React for component-based apps
- Figma for continued design work
Example Prompts for Side Projects
Landing Page
A SaaS landing page with:
- Hero section with headline, subheadline, and CTA button
- 3 feature cards with icons
- Testimonial section with user avatar and quote
- Pricing section with 2 plans
- Footer with links
Use a modern, clean style with blue as the primary color.
Dashboard
An analytics dashboard with:
- Sidebar navigation with icons
- Top bar with user avatar and notifications
- 4 stat cards showing key metrics
- Line chart for traffic over time
- Recent activity list
Dark theme preferred.
Mobile App Screen
A task manager mobile app main screen:
- Header with app name and add button
- Tab bar for Today, Upcoming, Completed
- Task list with checkboxes and due dates
- Floating action button to add task
iOS style, light theme.
E-commerce
A product detail page:
- Product image gallery with thumbnails
- Product title, price, and rating stars
- Size and color selectors
- Add to cart button
- Product description tabs
- Related products section
Code Quality
The generated code is clean and production-ready:
<section class="hero">
<div class="container">
<h1 class="hero-title">Build Your Side Project Faster</h1>
<p class="hero-subtitle">From idea to launch in days, not months</p>
<a href="#" class="btn btn-primary">Get Started Free</a>
</div>
</section>
.hero {
padding: 4rem 1rem;
text-align: center;
background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
color: white;
}
.hero-title {
font-size: 2.5rem;
font-weight: 700;
margin-bottom: 1rem;
}
.btn-primary {
display: inline-block;
padding: 0.75rem 2rem;
background: white;
color: #667eea;
border-radius: 8px;
font-weight: 600;
text-decoration: none;
}
The code:
- Uses semantic HTML
- Follows modern CSS practices
- Is responsive by default
- Is easy to customize
- Works with Tailwind when you choose that export option
Tips for Better Results
1. Be Specific
Include details about:
- Layout structure
- Colors and style
- Specific components needed
- Device target (mobile/desktop)
2. Reference Existing Designs
A pricing page similar to Stripe's pricing page style,
with 3 tiers and a comparison table below
3. Iterate in Steps
Start with the main layout, then refine sections:
1. Generate basic page structure
2. Refine hero section
3. Improve specific components
4. Add final details
4. Use Image Input
Sketch your idea on paper, take a photo, and upload it. Stitch interprets hand-drawn wireframes surprisingly well.
5. Leverage Multi-Select
When working on multiple screens, use Shift+click to select them all and apply consistent styling or theme changes in one prompt.
6. Use the Annotate Feature
For precise changes, open Annotate and draw directly on the screen to show exactly what you want modified. This is faster than describing complex layout changes in text.
Limitations
What Stitch cannot do:
- Complex JavaScript functionality or interactions
- Backend integration
- Real-time collaboration (it is an individual tool)
- Custom design tokens or brand guidelines
- Fully responsive layouts (may need manual adjustment)
- Deep design thinking like visual hierarchy or user journey mapping
Think of Stitch as a powerful starting point, not a complete design-to-deployment solution. You will still need to refine the output and add functionality.
Stitch vs Other AI Design Tools
| Tool | Best For | Price | Export |
|---|---|---|---|
| Google Stitch | Quick prototypes, static UI | Free | HTML, CSS, Tailwind, JSX, Figma |
| v0 by Vercel | React/Next.js components | Free tier + paid | React, Svelte, Vue |
| Lovable | Full app prototypes | Free tier | Full stack |

Use Stitch when:
- You need quick HTML/CSS or Tailwind code
- You are prototyping ideas visually
- You want a free option with generous limits
- You are building a side project and need UI fast
- You prefer exporting to Figma for further refinement
Use v0 when:
- You are building with React/Next.js
- You need component-based code
- You want full-stack capabilities
Use Bolt.new or Lovable when:
- You need a complete working application
- You want backend, auth, and database included
Workflow for Side Project Builders
Here is how to integrate Stitch into your workflow:
1. Ideation (5 minutes)
Write down what screens you need:
- Landing page
- Dashboard
- Settings page
2. Generate with Stitch (30 minutes)
Create each screen with prompts. Use the Prototypes feature to connect screens and visualize the user flow.
3. Export and Integrate (1-2 hours)
- Export code in your preferred format (HTML/CSS, Tailwind, or JSX)
- Copy structure into your views
- Adapt to your framework if needed
- Replace placeholder content
4. Add Functionality
- Connect to your backend
- Add JavaScript interactions
- Implement real data
- Test and refine
Total time saved: Hours of fighting with CSS layouts and design decisions.
