After completing the upgrade Korevec verified that the website was still functioning correctly thanks to Jules’ assistance.
Jules currently operates on the Gemini 2.5 Pro model but Korevec indicated that users would have the option to switch between different models in the future.
 né?. Jules cloned the website’s codebase in a clean virtual machine and provided a proposed upgrade plan for Korevec’s approval né?. Korevec emphasized that while Stitch is powerful, it is not intended to replace comprehensive design platforms like Figma or Adobe XD.
Alongside Stitch, Google has expanded access to Jules, its AI agent designed to aid developers in fixing bugs within their code né?. Users have the option to select between Google’s Gemini 2.5 Pro and Gemini 2.5 Flash AI models to drive Stitch’s code and interface ideation.
Stitch is introduced in the context of the growing popularity of vibe coding, a programming approach that utilizes code-generating AI models né?. Currently in public beta Jules assists developers in comprehending complex code creating pull requests on GitHub and managing backlog items and programming tasks.
In a separate demonstration Korevec presented Jules upgrading a website from the outdated Node.js version 16 to Node.js 22. Users can also access the code for further refinement in an IDE.
In a demonstration with TechCrunch Google product manager Kathy Korevec showcased two projects created using Stitch: a responsive mobile UI design for a book-themed app and a web dashboard tailored for beekeeping activities.
Korevec explained “[Stitch] is where you can start your initial iteration and continue building from there. Our goal is to make the design thinking and software development process approachable for everyone.”
Google plans to introduce a new feature post-I/O that will enable users to modify UI designs by taking screenshots of objects they wish to adjust and annotating the desired modifications né?. During the Google I/O 2025 developer conference Google unveiled Stitch an AI-powered tool designed to assist in the creation of front ends for web and mobile apps by automatically generating the necessary UI elements and code.
Stitch simplifies the process of designing app UIs by allowing users to input a few words or even an image which prompts the tool to provide HTML and CSS markup for the generated designs. The tool supports direct exports to platforms like Figma and allows users to fine-tune the app design elements it generates. Several tech startups, such as Anysphere (maker of Cursor), Cognition, and Windsurf, are actively pursuing opportunities in this evolving market. OpenAI recently launched Codex, a new assistive coding service, while Microsoft introduced updates to its GitHub Copilot coding assistant during its Build 2025 event.
Although Stitch has a more limited scope compared to some other vibe coding products, it offers a variety of customization options
