Google Stitch Complete Guide: How to Design UIs with AI (2026)

Google Stitch is the most significant shift in UI design since Figma went browser-based. Within weeks of its launch at Google I/O 2025, it caused Figma's stock to drop 10% in a single day. That alone tells you designers and developers are paying attention.

I've been using Stitch since its early access and have run it through its paces across app designs, web interfaces, and design system builds. This guide covers everything: what it is, how it actually works, how to write prompts that produce great results, and how to take a design from Stitch all the way to production code.

What is Google Stitch?

Google Stitch is a free, AI-powered UI design tool built by Google Labs. It lives at stitch.withgoogle.com and runs entirely in your browser — no downloads, no installs.

At its core, Stitch does two things:

Turns a text prompt or uploaded image into a polished UI design
Generates the production-ready HTML/CSS code for that design

It's powered by Google's Gemini AI models and operates on an infinite canvas — similar to Figma or Miro but AI-native from the ground up.

Who is Stitch For?

Stitch is genuinely useful for a wide range of people:

Designers who want to explore ideas fast without starting from a blank canvas
Developers who need a design to hand off or build from but don't have a designer on the team
Product managers and founders who want to prototype ideas before involving a designer
Freelancers building client proposals quickly
Students learning UI design or building portfolio projects

You don't need design experience to get value from Stitch. But if you do have design experience, you'll get significantly better results.

How Google Stitch Works

Stitch uses Google's Gemini multimodal AI to interpret your input — whether that's a paragraph of text, a hand-drawn sketch photo, or a screenshot of an existing app — and generates a complete UI with components, layout, typography, colour palette, and spacing.

Every design also produces a corresponding code panel with clean HTML and CSS. This isn't placeholder boilerplate — it's structured, ready-to-use frontend code.

The workflow looks like this:

Your Input (text or image)
         ↓
  Gemini AI interprets intent
         ↓
  UI Generated on Canvas
         ↓
  HTML/CSS Code Generated
         ↓
  Export: Figma / Code / MCP

Getting Started with Google Stitch

Step 1: Access Stitch

Go to stitch.withgoogle.com. Sign in with your Google account — that's all the setup required. No credit card, no waitlist as of 2026.

Step 2: Choose Your Input Method

Stitch supports three ways to kick off a design:

Text Prompt Type a description of what you want to build. This is the most common method and works well for most use cases.

Image Upload Upload a sketch, wireframe, screenshot, or photo. Stitch will interpret the visual and generate a corresponding digital UI. This is excellent for translating whiteboard sessions into real designs.

Voice (Voice Canvas) Use the Voice Canvas feature to speak your design instructions. The AI listens, asks clarifying questions in real time, and makes live updates on the canvas as you talk.

Step 3: Write Your First Prompt

For a first attempt, try something like:

"Design a mobile login screen for a fitness tracking app. Use a dark theme with electric blue accents. Include email and password fields, a 'Sign In' button, a 'Forgot Password' link, and a Google sign-in option."

Click generate. Stitch will produce a complete, styled screen in seconds.

Step 4: Refine with Follow-Up Prompts

Your first generation is a starting point, not a final design. Use follow-up prompts to iterate:

"Change the button colour to green and make it rounded"
"Add a profile avatar in the top right corner"
"Make the typography larger and switch to Inter font"
"Show me a light mode version of this"

Stitch maintains context between prompts, so each refinement builds on the previous one.

Step 5: Export Your Design

Once you're happy with a screen, you have three export options:

Copy HTML/CSS — grab the code directly from the code panel
Export to Figma — exports as properly structured components with Auto Layout and named layers
MCP server — connect directly to an AI coding agent (like Antigravity) for immediate frontend implementation

Google Stitch Key Features (2026)

Vibe Design

Vibe Design replaces the traditional wireframe-first workflow. Instead of specifying exact components and layouts, you describe:

A business objective ("I want users to feel trust immediately when they land on this page")
A design inspiration ("Think Notion meets Apple — clean, minimal, spacious")
A desired user emotion ("This should feel exciting and fast-paced")

Stitch interprets the vibe and generates multiple design directions for you to explore. It's a fundamentally different way to start a design — broader and more creative than a spec-driven approach.

When to use Vibe Design: Early in the design process when you're exploring directions, or when you want to generate options to present to a client.

Voice Canvas

Voice Canvas lets you speak directly to your canvas. Activate it and start talking:

"Give me three different layouts for a product card — one minimal, one image-heavy, one with a bold price callout"

The AI responds conversationally, asks follow-up questions if needed, and updates the canvas in real time. It can also give design critique — ask it to review your layout and it will flag issues with hierarchy, spacing, or accessibility.

When to use Voice Canvas: When you're exploring ideas rapidly, when you want to stay in flow without switching to a keyboard, or when you want AI-driven design critique.

Multi-Screen Prototyping

Available since December 2025, multi-screen prototyping lets you:

Generate multiple screens on the same canvas
Connect them into a clickable prototype
Define interaction flows between screens
Click "Play" to preview the experience

Stitch can also auto-generate logical next screens. If you have a login screen selected, ask it to generate the home screen that follows, and it will create a contextually appropriate continuation.

The result: You can go from a text prompt to a clickable multi-screen prototype in under 10 minutes.

Direct Edits

The March 2026 update added manual editing directly on the canvas:

Click any text element and rewrite it
Swap images
Adjust spacing and padding
Move components

This closes the gap between AI generation and the final polish a design always needs. You no longer have to re-prompt for small text changes.

DESIGN.md — Your AI Design System

DESIGN.md is one of Stitch's most powerful and underused features.

It's a plain-text document that defines your design system: colour palette, typography, component patterns, spacing rules, do's and don'ts. When you attach a DESIGN.md to your Stitch workspace, every screen Stitch generates follows those rules automatically.

Example DESIGN.md structure:

# Design System

## Colours
- Primary: #3B82F6 (blue)
- Secondary: #10B981 (green)
- Background: #0F172A (dark)
- Surface: #1E293B
- Text Primary: #F8FAFC
- Text Secondary: #94A3B8

## Typography
- Font: Inter
- Heading: 32px/700 weight
- Body: 16px/400 weight
- Caption: 12px/400 weight

## Components
- Buttons: Rounded (8px radius), no shadows
- Cards: 12px radius, 1px border
- Inputs: Outlined style, 8px radius

## Rules
- Never use pure black (#000000)
- Always maintain 4:5:1 contrast ratio minimum
- Spacing uses 8px grid

With this in place, every new screen you generate will feel like part of a coherent product — not a random collection of AI outputs.

How to Write Prompts That Work

Prompting is a skill. These are the patterns that consistently produce better results in Stitch.

Be Specific About the Context

Bad prompt:

"Design a dashboard"

Good prompt:

"Design a web app analytics dashboard for a SaaS product. Show a sidebar navigation on the left with sections for Overview, Traffic, Conversions, and Settings. The main area should show three KPI cards at the top (Total Users, Monthly Revenue, Churn Rate), followed by a line chart for traffic over the last 30 days."

The more context you give, the less Stitch has to guess.

Specify the Platform

Always state whether you're designing for mobile (iOS/Android) or web. The component styles, spacing, and interaction patterns differ significantly.

"Design a mobile iOS screen..."
"Design a responsive web page..."
"Design a tablet-optimised layout..."

Describe the User and Their Goal

"Design an onboarding screen for a meditation app. The user is a stressed professional. The screen should feel immediately calming — soft colours, generous whitespace, no visual clutter."

Framing the design around the user shifts the output from generic UI to purposeful UI.

Focus on One Screen or Component Per Prompt

Don't try to design an entire app in one go. Start with your most important screen, get it right, then build outward.

Start with the hero screen or core flow
Use multi-screen generation once you have a locked design language
Generate components (buttons, cards, modals) separately when needed

Use Iteration, Not Re-generation

When you get a close result, don't start over — iterate:

"Keep this layout but change the colour scheme to light mode"
"The spacing feels too tight — increase padding throughout"
"Replace the hero image placeholder with a gradient background"

Each small prompt builds on a design you already like rather than gambling on a fresh generation.

Exporting to Figma

The Figma export is Stitch's most practical feature for professional workflows.

When you export a screen to Figma, it arrives as:

Properly structured frames — not a flat image
Auto Layout applied — components have real layout constraints
Named layers — organised layer panel, not a mess of auto-named groups
Components — repeated elements are recognised and exported as Figma components

This is a working design file, not just a reference image. A designer can take it into Figma and keep working from there without having to rebuild from scratch.

Export steps:

Select the screen(s) you want to export on the canvas
Click the Export button in the top toolbar
Choose "Export to Figma"
Authenticate with your Figma account
Select the target file and page
Click Export

Using Stitch's HTML/CSS Output

The code Stitch generates is clean, readable HTML and CSS. It won't win awards for advanced architecture, but it's a solid starting point for frontend implementation.

What the code includes:

Semantic HTML structure
CSS custom properties for colours and typography
Flexbox/Grid for layout
Responsive considerations (especially for web designs)

What you'll typically need to add:

JavaScript for interactions
Form validation logic
API connections
Responsive breakpoints for complex layouts
Accessibility attributes (aria labels, roles)

For simple landing pages or marketing screens, Stitch's code can be close to production-ready. For complex interactive interfaces, treat it as a solid foundation to build on.

Google Stitch vs Figma

Since Stitch caused a notable dip in Figma's stock, the comparison is inevitable.

Feature	Google Stitch	Figma
AI Generation	Native, core feature	Plugin-based (third-party)
Price	Free (350 gen/month)	Free tier + paid plans
Code Export	HTML/CSS built-in	Requires Dev Mode (paid)
Collaboration	Limited	Industry-leading
Component System	DESIGN.md	Full design systems
Prototyping	Basic multi-screen	Advanced interactions
Plugin Ecosystem	None yet	Extensive
Learning Curve	Very low	Moderate

The honest assessment: Stitch is not a Figma replacement for professional design teams doing complex product work. It is, however, a genuine threat to Figma for early-stage exploration, rapid prototyping, and solo designers or small teams who don't need the full Figma ecosystem.

For many use cases — client proposals, hackathon projects, solo side projects, MVP validation — Stitch will be the better choice purely on speed.

Google Stitch Pricing

As of April 2026, Stitch is completely free:

Plan	Generations/Month	Model
Standard	350	Standard Gemini model
Experimental	50	Latest experimental model

No credit card required. No paid tier currently exists — Stitch is a Google Labs experiment, which means pricing could change, but for now there's no reason not to use it.

Practical Workflow: From Idea to Production

Here's a complete end-to-end workflow using Stitch alongside your existing tools:

Phase 1: Ideation (Stitch — 20 minutes)

Use Vibe Design to explore 2–3 design directions
Pick the direction that best fits your brief
Generate the core screen (usually home or login)
Establish colour palette and typography

Phase 2: Design (Stitch — 1–2 hours)

Set up your DESIGN.md with locked design decisions
Generate each key screen using specific prompts
Connect screens into a prototype
Use Direct Edits for final text and spacing polish
Get Voice Canvas to critique your layout

Phase 3: Handoff

Option A — Developer Handoff:

Copy HTML/CSS from the code panel
Provide alongside annotated screenshots
Developer adapts the code to their framework

Option B — Design Handoff:

Export to Figma
Designer refines and builds out edge cases
Standard Figma handoff to dev

Option C — AI Coding Agent:

Connect via MCP server
Pass the Stitch design directly to an AI coding agent
Agent generates framework-ready code (React, Vue, etc.)

Common Mistakes to Avoid

Trying to generate too much at once Stitch performs best on focused, single-screen prompts. Don't ask it to generate an entire 10-screen app in one prompt — the quality drops significantly.

Ignoring the code panel Many users treat Stitch as a pure design tool and miss the code output entirely. Even if you're a designer, having the HTML/CSS gives you and your developers a huge head start.

Not setting up DESIGN.md If you're building more than 2 screens, set up a DESIGN.md file. Without it, each generation will drift in colour and style, and your design won't feel cohesive.

Treating the first generation as final The first output is always a starting point. The real value comes from 3–5 rounds of targeted iteration. Don't accept a mediocre first generation when one follow-up prompt would have improved it significantly.

Skipping the Figma export Even if you plan to write the code yourself, exporting to Figma gives you a precise reference with real dimensions, font sizes, and colour values. It's worth the extra 30 seconds.

FAQ

Is Google Stitch free to use?

Yes. As of April 2026, Stitch is completely free. You get 350 generations per month on the standard model and 50 per month on the experimental model. No credit card is required.

Does Google Stitch require design experience?

No. Stitch is designed to be accessible to non-designers. However, having a basic understanding of UI design principles will help you write better prompts and get better results.

Can I use Google Stitch for commercial projects?

Yes. Designs created in Stitch can be used for commercial purposes. Review Google Labs' current terms of service at stitch.withgoogle.com for the latest usage terms.

What file formats can I export from Google Stitch?

You can export HTML/CSS code directly, export to Figma as a structured design file, or connect via MCP server to AI coding agents. Image export (PNG/SVG) is also available for individual screens.

How does Google Stitch compare to Midjourney or DALL-E for design?

Stitch is fundamentally different. Midjourney and DALL-E generate images — flat, non-editable visuals. Stitch generates real UI designs with structure, components, and code. Stitch output can be directly implemented; Midjourney output cannot.

Can Google Stitch replace a designer?

For early-stage exploration and rapid prototyping, Stitch can do what used to require hours of designer time in minutes. For complex product design work — interaction design, edge cases, accessibility, multi-platform systems — a skilled designer still adds significant value that Stitch cannot match.

What is Voice Canvas in Google Stitch?

Voice Canvas is a feature that lets you speak to the canvas instead of typing. You describe what you want out loud, the AI listens and responds conversationally, and updates your design in real time. It also supports asking the AI to critique your current layout.

What is Vibe Design in Google Stitch?

Vibe Design is an input mode where instead of specifying exact UI components, you describe the feeling, emotion, or business objective you want the design to achieve. Stitch interprets the vibe and generates multiple design directions to explore.

Google Stitch has compressed what used to be a multi-day design process into minutes. Whether you're validating a product idea, building a client proposal, or just trying to get a working design in front of users faster, Stitch is worth adding to your toolkit.

Start at stitch.withgoogle.com — you'll have your first design in under five minutes.
