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.
About Google Disco
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.
Pricing
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.
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, which scored 76.2% on SWE-bench Verified and a 1487 ELO rating on WebDev Arena.
- 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.
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 Gemini 3, currently one of Google's strongest reasoning models, which should make Disco's mini apps more reliable than AI browser features built on smaller models.
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
How much does Google Disco cost in 2026?
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.
Is Google Disco free to use?
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.
What are the best alternatives to Google Disco?
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.
How does Google Disco compare to Perplexity's Comet in 2026?
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.
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 a cross-platform AI browser that can act on the web today; pick Disco if you're on macOS and want Gemini 3 to turn tabs into structured apps.
- ChatGPT (Atlas): Pick Atlas if you want a paid autonomous agent mode that completes tasks for you; pick Disco if you want a free, read-only way to organize open tabs into a mini app.
