What is Stitch?
Stitch is an AI-powered UI design tool developed by Google Labs that enables UI/UX Designers, Developers, and Product teams to transform natural language prompts, sketches, or screenshots into structured interface layouts for web and mobile applications. It leverages Google's Gemini models to generate designs and associated front-end code, with exports to Figma or HTML/CSS. The tool's primary function is to accelerate the initial stages of UI/UX design by generating high-fidelity interface mockups from various inputs, including text, images, and voice. Stitch 2.0, an update released in March 2026, enhanced capabilities with an AI-native infinite canvas, multi-screen generation, and voice interaction features. It operates on Google's Gemini 2.5 Flash for speed in Standard mode and Gemini 2.5 Pro for higher fidelity in Experimental mode, with mentions of Gemini 3.1 Pro and Flash models powering the AI as of April 2026.
