At the Google I/O 2025 developer conference, Google unveiled Stitch, an innovative AI-driven tool designed to assist in creating user interfaces (UIs) for web and mobile applications. This tool simplifies the development process by generating essential UI components and corresponding code from brief textual prompts or even images.
Stitch enables users to request app UIs and delivers HTML and CSS coding based on their requirements. It operates on two advanced AI models: Gemini 2.5 Pro and Gemini 2.5 Flash, allowing for diverse coding and interface creation.
Stitch enters the growing domain of “vibe coding,” where developers leverage AI to generate code with minimal input. Competing products are emerging in this expanding sector, including those from startups like Anysphere and Cognition. Recently, OpenAI launched Codex, a similar coding assistance service, while Microsoft showcased enhancements to its GitHub Copilot.
Though Stitch may not offer the extensive capabilities of some other coding aids, it boasts various customisation options. Users can export designs directly to Figma and modify code for further development in integrated development environments (IDEs). Customisation features also extend to the design elements that Stitch generates.
In a demonstration with TechCrunch, Google product manager Kathy Korevec presented two examples created with Stitch: a mobile UI for a book-related app and a web dashboard tailored for beekeeping enthusiasts. Korevec emphasised that Stitch aims to facilitate the initial design iterations, making it easier for users to further evolve their projects.
Anticipating future enhancements, Google plans to introduce a feature that allows users to refine UI designs by taking screenshots of elements they wish to modify and annotating desired changes. While Stitch offers robust functionality, it is not intended to serve as a comprehensive design platform like Figma or Adobe XD.
In addition to Stitch, Google has enhanced Jules, its AI tool for bug fixing in code, which is now available in public beta. Jules assists developers in comprehending complex codes, creating GitHub pull requests, and managing various programming tasks. In a demo, Korevec displayed how Jules managed to upgrade a website from Node.js version 16 to the current Node.js 22, demonstrating its ability to execute complex coding tasks efficiently.
Jules currently utilises the Gemini 2.5 Pro model, with plans for future capabilities that will allow users to switch between different AI models, enhancing its flexibility and usability.
Overall, Google’s introduction of Stitch and the improvements to Jules signify the tech giant’s commitment to streamlining coding practices and empowering developers with cutting-edge AI tools.
