Google Disco is Google's Chromium browser: GenTabs uses Gemini 3 to build no-code mini apps from open tabs. A free, macOS-only closed beta, waitlist required.
Google Disco is an experimental Chromium browser that Google Labs launched on December 11, 2025. Its GenTabs feature studies a person's open browser tabs and chat history to assemble interactive, no-code mini apps, such as trip planners or price-comparison grids, using Gemini 3 and linking each element to its source page.
Google Disco is an experimental Chromium browser from Google Labs, announced December 11, 2025, built to test how AI can reshape browsing rather than just add a chat sidebar to it. Its flagship feature, GenTabs, turns a pile of open tabs and recent chat history into an interactive, no-code mini app suited to the task at hand, whether that is a meal planner, a cherry-blossom trip itinerary, or a shopping comparison grid. GenTabs works by continuously analyzing page structure and content across open tabs, then synthesizing that unstructured web data into a working interface the moment a user describes what they need in plain language. Every generated element links back to the original source page, so the app behaves as a structured layer over the live web rather than a static AI summary. The whole experience runs on Gemini 3, Google's own foundation model, reasoning across many tabs and chat turns at once through a large context window. Disco is aimed at people juggling many open tabs on a single complex task: trip planners comparing flights and hotels across sites, shoppers cross-checking prices at multiple retailers, and parents or educators putting together quick interactive learning aids. It is not built as a professional developer tool; Google frames it as an early discovery vehicle for ideas that may later fold into Chrome or other products. Disco is currently free, with no announced pricing plan, but access is limited to a closed beta on macOS only, gated behind a waitlist at labs.google/disco. Windows support has not shipped yet, and there is no iOS or Android build. Google has said explicitly that not everything will work perfectly at this stage and that tester feedback will shape what, if anything, ships more broadly.
Free during the closed beta, with no paid tier or subscription announced. Access requires an invite from the waitlist at labs.google/disco; Google has not said what, if anything, Disco will cost after it leaves Google Labs experimental status.
Google Disco is free during its closed beta, and Google has not announced a paid tier or subscription price for the browser. Google has said only that successful features may later fold into other Google products, without naming a price for that.
Yes, Disco is entirely free while it remains an experimental Google Labs project, with no seat limits or feature paywall inside the beta itself. The real limit is access rather than cost: macOS only, and Google can end or change the experiment at any time.
Perplexity's Comet browser is the closest cross-platform rival, running on Windows, macOS, iOS, and Android with a free core tier. OpenAI's ChatGPT Atlas offers a stronger autonomous agent mode but stays macOS-only. Arc Browser suits users who want AI-assisted browsing without a waitlist.
Comet already ships on four platforms and can complete purchases or fill forms directly, while Disco stays macOS-only and limits itself to building read-only mini apps from your tabs. Disco's edge is Gemini 3's context window, which lets GenTabs reason over more open tabs at once than Comet typically handles in one session.
Request access with a Google account at labs.google/disco, since entry is invite-only during the closed beta. Once approved, install the macOS build, open a few tabs on a task like trip planning, and describe the app you want in plain language for GenTabs to build around them.
