On the Google I/O 2025 developer convention, Google launched Sew, an AI-powered software to assist design internet and cell app entrance ends by producing the required UI parts and code.
Sew may be prompted to create app UIs with a number of phrases and even a picture, offering HTML and CSS markup for the designs it generates. Customers can select between Google’s Gemini 2.5 Professional and Gemini 2.5 Flash AI fashions to energy Sew’s code and interface ideation.
Sew arrives as so-called vibe coding — programming utilizing code-generating AI fashions — continues to develop in reputation. There’s various massive tech startups going after the burgeoning market, together with Cursor maker Anysphere, Cognition, and Windsurf. Simply final week, OpenAI launched a brand new assistive coding service referred to as Codex. And yesterday throughout its Construct 2025 kickoff, Microsoft rolled out a sequence of updates to its GitHub Copilot coding assistant.
Sew is a little more restricted in what it might probably do in comparison with another vibe coding merchandise, however there’s a good quantity of customization choices. The software helps instantly exporting to Figma and may expose code in order that it may be refined and labored on in an IDE. Sew additionally lets customers fine-tune any of the app design parts it generates.
In a demo with TechCrunch, Google product supervisor Kathy Korevec confirmed two tasks created utilizing Sew: a responsive cell UI design for an app for bookworms and an internet dashboard for beekeeping.
“[Stitch is] where you can come and get your initial iteration done, and then you can keep going from there,” mentioned Korevec. “What we want to do is make it super, super easy and approachable for people to do that next level of design thinking or that next level of software building for them.”
Quickly after I/O, Google plans so as to add a function that’ll enable customers to make adjustments of their UI designs by taking screenshots of the article they need to tweak and annotating it with the modifications they need, Korevec mentioned. She added that whereas Sew in all fairness highly effective, it isn’t meant to be a full-fledged design platform like Figma or Adobe XD.
Alongside Sew, Google has expanded entry to Jules, its AI agent aimed toward serving to builders repair bugs of their code. Now in public beta, the software helps builders perceive complicated code, create pull requests on GitHub, and deal with sure backlog gadgets and programming duties.
In a separate demo, Korevec confirmed Jules upgrading a web site working the deprecated Node.js model 16 to Node.js 22. Jules cloned the location’s codebase in a clear digital machine and shared a “plan” for the improve, which Korevec was then prompted to approve. As soon as the improve was accomplished, Korevec requested Jules to confirm that the web site nonetheless labored accurately — which Jules did.
Jules presently makes use of Gemini 2.5 Professional, however Korevec instructed TechCrunch that customers will have the ability to swap between totally different fashions sooner or later.
