At the Google I/O 2025 developer conference, Google introduced Stitch, an innovative AI-powered tool aimed at streamlining the design process of web and mobile applications by automating the creation of user interface components and their corresponding code.
Stitch enables users to quickly generate app interfaces by simply inputting a brief text prompt or uploading an image for inspiration. From these simple prompts, the platform can develop fully structured designs, including HTML and CSS markup ready to use. Google’s new service leverages two of its advanced artificial intelligence models: Gemini 2.5 Pro and Gemini 2.5 Flash, depending on the user’s needs and preferences.
The launch comes at a time when “vibe coding,” the term used for AI-assisted coding workflows, is seeing significant growth. The market for such services is attracting major interest, evidenced by recent developments in competing startups and tech giants alike. Recently, companies such as Anysphere, Cognition, and Windsurf have introduced their versions of AI-powered coding assistants, joining OpenAI with its Codex service and Microsoft, which unveiled fresh updates to its GitHub Copilot assistant during its own Build 2025 conference.
According to Google Product Manager Kathy Korevec, Stitch isn’t designed to replace full-scale UI design platforms like Figma or Adobe XD, but rather acts as a convenient starting point. Users can export designs directly into Figma and adjust the generated code outputs within their preferred development environments. Additionally, users can further customize elements provided by Stitch to refine their designs.
In a demonstration, Korevec showcased Stitch’s capabilities through two practical projects: a responsive mobile interface designed for book lovers and an intuitive web dashboard suitable for beekeepers. “Stitch gives you an accessible entry point,” Korevec explained. “It simplifies initial iterations, allowing designers and developers to focus on the creative enhancements and refinements required later in the design process.”
Google intends to broaden Stitch’s functionality shortly after the I/O conference. Upcoming enhancements include a feature allowing users to edit UI designs through annotations made directly on screenshots, emphasizing the company’s goal of balancing ease-of-use with practical utility.
Alongside Stitch’s announcement, Google also expanded access to its companion AI tool, Jules, designed primarily for debugging and task automation for developers. Now entering public beta, Jules has been designed to simplify everyday coding challenges, such as updating codebases, generating pull requests, and managing coding tasks. Korevec demonstrated Jules’ ability to automatically upgrade a website coded in an obsolete Node.js version to its latest iteration seamlessly.
Currently powered by Gemini 2.5 Pro, Jules will soon accommodate alternative AI model choices to better tailor its responses to developer needs, Korevec said.
Through these sequential announcements, Google underscores its ongoing commitment to AI-driven software development tools that promise substantial productivity advances for both developers and designers.
