Stitch is an AI design canvas from Google Labs that generates user interfaces for mobile and web apps. Users describe an app in plain language or upload hand-drawn wireframes or screenshots, and Stitch produces editable screens along with matching front-end code.

Key features:

Generates UI designs with Gemini models from prompts, sketches or screenshots.
Iterates on designs with follow-up edits.
Builds multi-screen prototypes linked by interaction hotspots.
Exports semantic HTML and CSS with Tailwind support.
Exports to Figma with Auto Layout, named layers and editable text.
Connects to AI coding agents such as Antigravity over MCP for two-way edits.

Stitch runs in the browser and includes templates for portfolios, dashboards, landing pages and mobile apps. Users own their generations. It is currently free with a daily credit limit that resets at midnight UTC, and is available in English to users 18 and over in countries where Gemini is available.
