At the 2025 Google I/O developer conference, Google introduced Stitch — an AI-powered tool designed to streamline the creation of web and mobile app front ends by generating UI elements and the corresponding code.

With just a few words or even an image as input, Stitch can produce complete app interfaces, providing the necessary HTML and CSS markup. Users can choose between Google's Gemini 2.5 Pro and Gemini 2.5 Flash models to power Stitch’s interface design and code generation capabilities.

Stitch arrives amid the rising trend of “vibe coding” — a style of programming that leverages AI models to generate code. A growing number of tech startups are entering this space, including Anysphere (maker of Cursor), Cognition, and Windsurf. Just last week, OpenAI launched a new assistive coding tool called Codex, and at its Build 2025 kickoff yesterday, Microsoft announced a series of updates to GitHub Copilot.

While Stitch is somewhat more limited compared to other vibe coding tools, it offers a range of customization features. Users can export designs directly to Figma, view and refine code within an IDE, and fine-tune the generated app elements.

In a demo with TechCrunch, Google product manager Kathy Korevec showcased two Stitch-generated projects: a responsive mobile UI for a book-focused app and a web dashboard for beekeeping.

“[Stitch is] where you can come and get your initial iteration done, and then you can keep going from there,” Korevec said. “We want to make it super easy and approachable for people to take that next step in design thinking or software development.”

Following I/O, Google plans to roll out a new feature allowing users to edit UI elements by taking a screenshot and annotating it with desired changes. Korevec emphasized that while Stitch is powerful, it's not intended to replace comprehensive design platforms like Figma or Adobe XD.

Alongside Stitch, Google has broadened access to Jules — its AI agent designed to help developers debug and manage code. Now in public beta, Jules assists with understanding complex codebases, creating pull requests on GitHub, and tackling backlog items and various programming tasks.

In a separate demo, Google product manager Kathy Korevec showcased Jules upgrading a website from the deprecated Node.js version 16 to Node.js 22. Jules cloned the site’s codebase in a clean virtual machine, generated an upgrade plan, and awaited Korevec’s approval before executing the changes. After the upgrade, Jules successfully verified that the website was functioning correctly.

Jules currently runs on Gemini 2.5 Pro, but Korevec noted that users will eventually be able to choose from multiple model options.

Introduction to Stitch

Stitch is a new AI-powered tool from Google designed to help create app front ends quickly and easily. It uses artificial intelligence to generate user interface designs and the corresponding code for web and mobile apps, making the app design process faster and more accessible.

How Stitch Works

Users provide Stitch with simple prompts—these can be text descriptions or even images. Using advanced AI models like Gemini 2.5 Pro and Gemini 2.5 Flash, Stitch interprets these inputs and generates complete UI layouts along with HTML and CSS code that developers can use directly.

Key Features of Stitch

• Generates UI designs from simple prompts or images
• Provides clean, ready-to-use HTML and CSS code
• Allows exporting designs to tools like Figma for further editing
• Let’s users customize and fine-tune generated designs
• Supports workflow integration by exposing code for editing in development environments

Stitch’s Role in the AI Coding Landscape

Stitch is part of the growing trend called “vibe coding,” where AI assists in programming tasks. While some tools focus on writing backend code or debugging, Stitch specializes in front-end UI design, helping developers’ prototype and build interfaces more efficiently.

Future Developments and Use Cases

Google plans to add features like editing UI by annotating screenshots. Currently aimed at initial design iterations rather than full-scale design platforms, Stitch helps users jumpstart app creation and refine their ideas faster. It’s especially useful for designers and developers looking to streamline early-stage app development.
