Google Unveils Stitch: An AI-Powered UI Design Tool for Developers
Google has launched Stitch, a new generative AI tool designed to streamline the UI design process for developers. Announced at Google I/O 2025, Stitch aims to rapidly transform UI ideas into functional, app-ready designs.
Powered by Gemini 2.5 Pro, Stitch allows developers to input text prompts and reference images to generate complex UI designs and front-end code in minutes. This innovation seeks to alleviate the manual effort traditionally required in creating design elements and subsequent programming.
Stitch generates visual interfaces based on selected themes and natural language descriptions (currently supporting English). Users can specify details such as color palettes and desired user experiences. Furthermore, visual references, including wireframes, sketches, and existing UI designs, can be uploaded to guide the generation process.
According to Google, Stitch enables users to produce multiple variants of an interface, facilitating experimentation with different styles and layouts. The tool generates UI assets alongside fully functional front-end code that can be directly integrated into apps or exported to Figma for further refinement and collaboration.
Kathy Korevec, a Google product manager, demonstrated Stitch's capabilities with two projects: a responsive mobile UI design for a book-related app and a web dashboard for beekeeping. She emphasized that Stitch is intended to help kickstart the initial design iteration and that users can continue refining their designs from there. As Korevec stated, "[Stitch is] where you can come and get your initial iteration done, and then you can keep going from there. What we want to do is make it super, super easy and approachable for people to do that next level of design thinking or that next level of software building for them."
Google plans to enhance Stitch with a screenshot editing feature, allowing users to make changes by annotating screenshots of the elements they wish to modify. However, Korevec clarified that Stitch is not meant to replace full-fledged design platforms like Figma or Adobe XD.
Alongside Stitch, Google is expanding access to Jules, its AI agent designed to assist developers in debugging code. Now in public beta, Jules helps developers understand complex code, create pull requests on GitHub, and manage backlog items. Korevec showcased Jules upgrading a website from Node.js version 16 to Node.js 22.
Google's Stitch represents a significant step in leveraging AI to simplify and accelerate the UI design process. Will this tool truly empower developers and change the future of app design? Share your thoughts and opinions in the comments below!
