Disco is Google Labs' browser experiment, announced on December 11, 2025. Its GenTabs feature studies open tabs and chat history to assemble interactive no-code mini apps, such as trip planners or price grids, with Gemini 3 and a source link on each element. Access is a macOS closed beta behind a waitlist.
About Google Disco
Google Disco is an experimental Chromium browser from Google Labs, announced on December 11, 2025, built to test how AI can reshape browsing rather than bolt a chat sidebar onto 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 trip itinerary or a shopping comparison grid.
GenTabs analyses the structure and content of your open tabs, then builds an interface the moment you describe what you need in plain language. Every generated element links back to the source page, so the app behaves as a structured layer over the live web rather than a static summary. It runs on Gemini 3, the model family that also powers the Gemini assistant, and reasons across many tabs and chat turns in one request. Google's Disco page, read on 26 October 2026, also lists a feature marked New, the AI-Enabled Pointer: point at anything on a page to put a question right there, carry on in a side panel, get scrolled to and shown the relevant passage, and save the best findings into a GenTab.
Disco is aimed at people juggling many tabs on one complex task: trip planners comparing flights and hotels, shoppers cross-checking retailers, and parents or educators putting together quick learning aids. It is not a developer tool, and Google frames it as a discovery vehicle for ideas that may later reach larger products. Other Google experiments in the catalog include Opal, Stitch, Google Lens and NotebookLM.
Who should skip it for now: anyone who needs a browser they can install today on Windows or a phone. Perplexity Comet, Dia and Arc are the closest installable AI browsers in the catalog, ChatGPT, Genspark and Microsoft Copilot cover the assistant-led route, and our write-up on Arc's 449 days is useful background on how fast this category moves. Disco is also a Labs experiment, and Labs ends experiments: Google shut down Mixboard on 28 September 2026, so nothing built in GenTabs should be treated as permanent. The beta is closed and macOS-only, with a waitlist at labs.google/disco and no Windows, iOS or Android build.
Pricing
Free during the closed beta, with no paid tier or subscription announced, and the vendor page still shows only a waitlist sign-up as of 26 October 2026. google/disco, and Google has not said what, if anything, Disco will cost after it leaves Labs experimental status. If you need a browser you can install today, compare Perplexity Comet or Dia first.
Key Features
- GenTabs app generation: Reads your open tabs and recent chat history to generate an interactive no-code mini app, such as a trip itinerary or comparison grid, from a plain-language request.
- Source-linked outputs: Every element GenTabs creates links back to the original webpage it was pulled from, so you can check the source instead of trusting an opaque AI summary.
- Adaptive rebuilding: GenTabs apps keep updating as you open new tabs or refine your prompt, rather than freezing as a one-time snapshot.
- Gemini 3 reasoning core: Runs on Google's Gemini 3 model family rather than a third-party LLM, so GenTabs can reason across many open tabs and chat turns in a single request.
- Chromium-based shell: Built on the open source Chromium engine that also powers Google Chrome, so the browsing interface feels familiar to existing Chrome users.
- AI-Enabled Pointer: Lets you select any part of a page and ask a question at the pointer, then continue in a side panel, jump to and highlight the relevant section, and add the best parts to a GenTab.
Pros
- Cuts the manual work of comparing options across many open tabs down to one auto-built app, a real fix for the tab fatigue most browsers ignore.
- Source linking on every generated widget makes the output easier to trust than a typical AI chat summary, since you can jump straight to the origin page.
- Runs on Google's own Gemini 3 models, which keeps GenTabs inside one vendor's stack instead of depending on a third-party LLM.
Cons
- Closed beta is macOS-only and invite-gated through a waitlist, so Windows, Linux, iOS, and Android users cannot try it yet.
- No pricing has been announced for after the beta, so anything built today with GenTabs could later sit behind a paywall.
- Google's own beta disclosures say it logs browsing content and AI chat activity during testing, ruling out sensitive or enterprise use for now.
Data Handling
- Training-data policy
- During the beta, Google logs browsing activity and AI chat content associated with Disco sessions; no data-training opt-out policy specific to Disco has been published as of this beta period.
Frequently Asked Questions
What will Google Disco cost?
Google Disco is free during its closed beta, and Google has not announced a paid tier or subscription price. Google has said only that successful features may later fold into other Google products, without naming a price for that.
Can anyone use Google Disco for free right now?
Not anyone: it costs nothing during the Labs beta, but entry is by waitlist invite and the build is macOS only. Google can also end or change the experiment at any time, as it did with Mixboard on 28 September 2026.
Which browsers compete with Google Disco?
Perplexity Comet, Dia and Arc are the nearest AI browsers you can install in the HokAI catalog, while ChatGPT and Genspark cover agent-style browsing. Disco differs by turning your tabs into a source-linked mini app instead of answering in a chat pane, but you need a waitlist invite to try it.
Is Google Disco a replacement for Perplexity Comet?
Not today. Disco is a macOS-only Labs beta that builds read-only mini apps from your tabs, while Comet is a shipped product you can install now; check its page for current platforms. Pick Disco only if the tabs-into-apps idea is what you want to test.
How do you get started with Google Disco?
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.
Top Alternatives
- Arc Browser: Pick Disco if you want Gemini 3 to auto-build task-specific mini apps from your tabs; pick Arc if you want a polished AI-assisted browser available today without a waitlist.
- Perplexity Comet: Pick Comet if you need an AI browser you can install today; pick Disco if you are on macOS and want Gemini 3 to turn tabs into structured apps.
