Google launches AI coding assistant and AI tool for UI designs at Google I/O 2025

Google has entered the AI coding segment with a new tool called Jules. The tool as introduced back in December last year to Google Labs and now its beta version will be available to the public.

Jules can write code, debug and perform tests just like other AI coding assistants. 

“It is an asynchronous, agentic coding assistant that integrates directly with your existing repositories. It clones your codebase into a secure Google Cloud virtual machine (VM), understands the full context of your project, and performs tasks like writing tests, building new features, providing audio changelogs and bumping dependency versions,” a blog posted by Google stated.

The tool will compete with existing AI coding agents like Cursor that are popular in the market. 

Additionally, Google also launched a new AI tool called Stitch so developers can quickly build UI ideas into app designs. Powered by Gemini 2.5 Pro, the tool is now available on Google Labs. 

Users just need to enter text prompts by referencing images which is then converted into UI designs and frontend code in a matter of minutes. The tool allows developers to experiment with different styles and layouts. 

Once the UI assets are generated with the front-end code they can be directly added into apps or exported to another design tool to refine further.
