Google thinks the future of the web isn’t just about making it agentic; it’s also about letting your browser build things for you. That idea is now real with “Disco”, the company’s experimental new AI-powered browser that vibe-codes an app based on what you are doing online. This feature of Disco is called “GenTab,” and is powered by Gemini 3.
As you might’ve guessed, GenTab takes your tab and chat history into consideration. It analyzes your tabs, your searches, and your chat prompts to generate tools that fit what you’re doing.
Google showed off a few examples, and they’re honestly pretty impressive. If you’re researching science topics like Entropy, Disco might spin up an “Entropy Explainer” app. The official video also shows a vibe-coded bunk bed comparison site and a memory match brain game.
Google’s new AI browsers vibe codes an app based on your tabs
GenTabs sit alongside regular tabs, but they get their own Gemini-like icon instead of a favicon. One demo showed a travel planner with calendars, route maps, crowd-level predictions, and quick-action buttons like “Book Nearby Stays.” Tap anything inside that app, and the GenTab reshapes itself in real time.
Disco greets you with a homepage containing a chatbox rather than the usual address bar. That’s where the chat history comes from, although you can also paste a URL in it.
If you end up conversing, Google will first suggest you relevant webpages, and after a few conversations, it pops up a prompt to create a GenTab based on what you’re searching.
AI is definitely changing the way we search and consume content. And it won’t surprise me that features like GenTabs are the next evolution of it.
You don’t need to write code; you just describe what you need, refine it in plain language, and the browser does the heavy lifting. Google says Disco is meant to help people “learn faster” and experiment with what browsing could become. And yes, the company admits the best concepts from Disco might eventually show up in Chrome.
For now, Disco is an early experiment. Google Labs has opened a waitlist, and the first version is rolling out only on macOS.
