Gemini CLI Extension: Stitch — AI Design Tool

What it is

Stitch is an official Gemini CLI extension from Google that integrates the Stitch AI design tool with the Gemini command-line interface. Once installed, Gemini CLI gains capabilities for AI-driven UI design, component generation, and design system management. The extension activates automatically when relevant tasks are detected during development sessions.

This extension targets developers using Gemini CLI who need to generate UI components, create design systems, or prototype interfaces without switching to a separate design tool.

How it saves time or tokens

The Stitch extension brings design capabilities directly into the terminal workflow. Instead of switching between a design tool and code editor, developers describe UI needs in natural language and the extension generates components inline. Design system management is handled through the same CLI interface used for coding.

How to use

1. Install Gemini CLI if not already installed.
2. Add the extension: gemini extensions install stitch.
3. Ask Gemini to use the Stitch extension for UI design tasks.

Example

# Install the extension
gemini extensions install stitch

# Use in a Gemini CLI session
gemini> Use the stitch extension to create a login form component
  with email, password fields, and social login buttons

# Generate a design system
gemini> Use stitch to create a design system with brand colors
  #1a73e8 and #34a853, rounded corners, and Inter font

# Create screen layouts
gemini> Use stitch to design a dashboard layout with sidebar
  navigation and a main content area with charts

Common pitfalls

• The extension requires an active Google account with API access; ensure your Gemini CLI is properly authenticated.
• Generated designs may need manual refinement for production use; treat output as a starting point rather than final designs.
• The extension is part of the Gemini ecosystem and requires Gemini CLI specifically; it does not work with other AI coding tools.
