Google debuts Disco to test AI-powered GenTabs apps

Google Labs has launched Disco, a testing environment for new web features, with an early focus on an AI-driven tool called GenTabs that generates interactive web applications from a user's browsing activity and prompts.

The company positioned Disco as a place to trial modern browsing concepts and observe how people interact with the internet when they face more complex online tasks. GenTabs is the first feature available for testing inside Disco.

Disco rollout

Google said GenTabs uses the Gemini 3 model. It analyses a user's open tabs and chat history. It then infers what the user is trying to achieve and proposes a software tool for that task.

The product centres on the idea that a user can describe what they need in natural language. GenTabs then generates an interactive web application that matches the request. The user can continue refining the output through conversation.

Google said users do not need coding knowledge to use the system. It framed the initial design around research and planning tasks that often involve many web pages and references.

"The web is a vast collection of applications and information, making it an incredible engine for discovery and learning. Yet, as our online tasks have grown more complex we've all felt the frustration of juggling dozens of open tabs to research a topic or plan a trip. We believe the web itself has the opportunity to adapt to the complexity, which is why we're introducing Disco, featuring GenTabs, the newest experiment from Google Labs," said Manini Roy, Senior Product Manager for AI Innovation, Chrome, Google.

How GenTabs works

Google described GenTabs as a proactive system that watches for context across what a person has open in the browser. It also uses the ongoing dialogue in the tool's chat interface.

GenTabs can suggest "generative apps" that the user did not request explicitly, based on the system's assessment of the task at hand. It can also assemble outputs that reference material from different sites and keep links back to those sources.

The company said each element created by the system includes a direct link to the original web sources used. It presented that approach as a way to keep the underlying information verifiable, rather than producing isolated output without attribution.

"GenTabs helps you navigate the web by proactively understanding your complex tasks (through your open tabs and chat history) and creating interactive web applications to help you complete the tasks. You never need to write a line of code: Just describe the tool you need and refine it using natural language. Depending on your current task, it will even create suggestions for generative apps that you hadn hadn't thought of yet. And because every generative element ties back to the web, it always links to the original sources," said Roy.

Early testing

Google said Disco sits in Google Labs, which the company uses for experiments that may or may not become product features. The initial availability targets a small group of participants, and access runs through a waitlist.

The company said early participants use the system for personal and educational projects. Examples include weekly meal plans, international travel itineraries, and visual guides to the solar system for children.

Roy said the company expects rough edges at this stage and plans to use feedback from testers to shape the next iteration.

"It's early, and not everything will work perfectly. We're starting with a small cohort of testers, and their feedback will help us understand what's useful, what needs work and what they'd like to see in the future. The most compelling ideas from Disco may one day make their way into larger Google products - but by putting this experiment in people's hands now, we can learn faster and together help shape the future of browsing," said Roy.

Platform focus

Google said the project currently sits in an experimental phase on macOS. The company said it intends to use data from Disco to guide decisions across its wider product ecosystem, including the possibility that successful features may later appear in broader web services.

"Disco is our new "Disco"very vehicle designed to reimagine browsing and building for the modern web. Disco will help us learn faster and work together with AI enthusiasts to shape the future of web browsing. And the first feature we're testing is GenTabs, which was built with Gemini 3, our most intelligent model," said Roy.

Google said macOS users can join the testing programme through a waitlist, and it plans to adjust the features based on how the initial cohort uses the tools and what they report back.
