On the Google I/O 2025 developer convention, Google launched Sew, an AI-powered instrument to assist design net and cell app entrance ends by producing the mandatory UI parts and code.
Sew might be prompted to create app UIs with a couple 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 quite a few 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 collection of updates to its GitHub Copilot coding assistant.
Sew is a little more restricted in what it might do in comparison with another vibe coding merchandise, however there’s a good quantity of customization choices. The instrument helps immediately exporting to Figma and might 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 initiatives created utilizing Sew: a responsive cell UI design for an app for bookworms and an internet dashboard for beekeeping.
“[Stitch is] the place you may come and get your preliminary iteration finished, after which you may maintain going from there,” mentioned Korevec. “What we wish to do is make it tremendous, tremendous straightforward and approachable for individuals to do this subsequent degree of design considering or that subsequent degree of software program constructing for them.”
Quickly after I/O, Google plans so as to add a characteristic that’ll permit customers to make adjustments of their UI designs by taking screenshots of the thing they wish to tweak and annotating it with the modifications they need, Korevec mentioned. She added that whereas Sew is fairly 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 instrument helps builders perceive complicated code, create pull requests on GitHub, and deal with sure backlog objects and programming duties.
In a separate demo, Korevec confirmed Jules upgrading a web site operating 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 appropriately — which Jules did.
Jules at present makes use of Gemini 2.5 Professional, however Korevec advised TechCrunch that customers will be capable to swap between completely different fashions sooner or later.
