Stitch & Jules, new AI agents by Google – AI News – #1 June 2025

Google once again proves it sits at the cutting-edge of innovation. We recently wrote about the hottest highlights from Google I/O 2025, and now a fresh wave of AI-powered tools is already on the horizon. This time the Mountain View giant unveils Stitch and Jules—two AI agents poised to revolutionise the daily work of designers and developers alike. Let’s take a closer look!

Have you ever had a brilliant user-interface idea get stuck somewhere between a designer’s vision and a developer’s constraints? Hours lost in explanations, revisions and attempts to translate a creative concept into working code—sound familiar? Google Labs decided to tackle that pain-point head-on with Stitch.

Stitch is an experimental tool that aims to become a true bridge between the worlds of design and development. Imagine that instead of manually converting mock-ups into code, you simply describe what you want—or upload an image—and the AI does the rest. Sounds like magic? A little, but that “magic” is powered by the multimodal capabilities of the Gemini 2.5 Pro model.

Born from the need to streamline designer-to-engineer collaboration, Stitch promises to make the UI creation process far smoother and more intuitive.

This tool offers several impressive capabilities:

If Stitch is set to become designers’ right hand, Jules aspires to be an autonomous partner for programmers. The agent has just entered public beta—open to everyone, no waitlists—wherever the Gemini model is available.

Jules is an autonomous agent capable of reading your code, understanding your intent and diving into work on its own. It operates asynchronously, cloning your repository to a secure Google Cloud VM to grasp full project context. It can:

Crucially, Jules presents its action plan and reasoning before applying any change, giving you the opportunity to tweak it. It works directly within your GitHub workflow, minimising context-switching. All of this is powered by the advanced code-reasoning abilities of the Gemini 2.5 Pro model. Privacy is paramount—Jules does not train on your private code; your data remains isolated. During the public beta, access to Jules is free (with certain usage limits).

Stitch and Jules are a clear signal that AI agents are entering a bold new phase. These tools don’t merely automate tedious tasks—they evolve into intelligent partners, capable of grasping complex intent and acting autonomously. The leap from prototype to production in “agentic development” is happening before our eyes, and it will undoubtedly reshape how we design interfaces and build software. Exciting times lie ahead for the creative and tech industries—stay tuned, because the AI revolution is only just picking up speed.
