Google introduces Stitch AI-powered tool for app design and development at Google I/O 2025

Google unveiled various important tools at its annual developer conference Google I/O 2025 . At the same event, the tech giant also introduced ’Stitch’ its new AI-powered tool which is designed to bridge the gab between design and development of app creation. The company claims that Stitch aims to transform how user interfaces (UIs) are conceptualized and built, making app design more accessible and efficient for both seasoned professionals and aspiring creators. “Introducing a new AI-powered tool to generate high-quality UI designs and corresponding frontend code for desktop and mobile by using natural language descriptions or image prompts. Stitch lets users bring ideas to life, lightning fast. Iterate on your designs conversationally, adjust themes, and easily export your creations to CSS/HTML or Figma to keep going,” said Google in a blog post.


How Stitch works

Stitch allows users to:

• Generate HTML and CSS markup for app designs using simple prompts.
• Choose between Gemini 2.5 Pro and Gemini 2.5 Flash AI models for interface ideation.
• Export designs directly to Figma or refine code in an Integrated Development Environment (IDE).
• Fine-tune UI elements with customisation options for themes, fonts, and layouts

Google product manager Kathy Korevec described Stitch as a tool for rapid iteration, enabling users to quickly prototype and refine app designs. “What we want to do is make it super easy and approachable for people to take their design thinking to the next level,” Korevec stated.
