Google Is Killing ChromeOS: Everything We Know About Aluminium OS, Its Android-Based Replacement

ChromeOS is dead. Google just won’t say the exact words.

At Google I/O on May 12, 2026, Google officially announced that its decade-old Chromebook operating system is being replaced by an entirely new platform — one built from the ground up on Android, with Gemini AI embedded at every level. The project, developed under the internal codename “Aluminium,” represents Google’s most ambitious operating system bet since Android itself.

This isn’t ChromeOS getting an Android app store bolted on (they already tried that — it didn’t work well). This is a full replacement. A new OS, new hardware partners, new device categories, and a new vision for what a Google laptop should be. The first consumer devices ship in Q3 2026.

What Is Aluminium OS?

Aluminium OS is an Android 17-based desktop operating system designed specifically for laptops and desktop computers. It replaces ChromeOS for consumer devices with a platform that runs native Android apps, supports a traditional desktop interface with a taskbar and virtual desktops, and integrates Gemini AI as a core operating system feature — not an add-on.

The key technical difference from ChromeOS: there is no translation layer. Previous attempts to run Android apps on Chromebooks used ARC (App Runtime for Chrome), a container that translated Android app calls into something the Chromium-based OS could understand. Apps performed poorly, crashed frequently, and had terrible keyboard and mouse support. Aluminium OS eliminates this problem entirely because the OS itself is Android. Apps run natively, which means better performance, proper input support, and access to the full Android app ecosystem.

Google clarified at I/O that “Aluminium” is a development codename, not the final consumer brand. A retail name will be unveiled later in 2026. However, the new laptop hardware will be branded Googlebook — Google’s answer to MacBook.

What’s Actually New

Gemini AI at OS Level

The most significant feature isn’t a better file manager or a nicer taskbar — it’s Gemini built into the operating system itself. Aluminium OS introduces Magic Pointer : shake your mouse cursor to contextually select items on screen. Gemini reads what you’re looking at and offers suggestions, actions, and prompts.

Hovering over a chart in a spreadsheet and shaking the cursor could trigger Gemini to offer analysis. Selecting a paragraph of text and activating Magic Pointer could offer rewrite suggestions, translation, or summarization. It’s the Gemini AI experience we covered in our Gemini in Docs, Sheets, and Slides guide, but extended to the entire OS rather than just Google Workspace apps.

Google’s broader AI Mode expansion — which already pulls context from Gmail and Photos — will be deeply integrated into Aluminium OS, giving the operating system access to your entire Google ecosystem for AI-powered suggestions.

Real Desktop Interface

Aluminium OS includes a bottom dock (similar to macOS), a system tray, virtual desktops for workspace organization, proper window management with snap layouts, a Files app with familiar folder navigation, and a built-in Linux terminal environment for developers. This isn’t a phone interface stretched across a 15-inch screen — it’s a genuine desktop experience built on Android’s foundation.

Phone Integration

A dedicated taskbar button lets you access apps mirrored from your Android phone. You can view notifications, respond to messages, and launch phone apps directly on the laptop screen. This is Google’s answer to Apple’s Continuity and Universal Control features that link iPhone and Mac.

Link to iOS

In a surprising move, Google confirmed a “Link to iOS” app that enables some interoperability with iPhones. Details are limited, but the announcement signals that Google isn’t limiting the new OS to Android phone users only — they want Aluminium OS laptops to work for iPhone users too.

Chrome Extensions Support

Aluminium OS supports Chrome browser extensions, addressing one of the biggest concerns from existing Chromebook users. Your extension library carries over from ChromeOS.

Hardware: Googlebook and Beyond

The first Aluminium OS devices will come from HP, Lenovo, Acer, and ASUS — the same manufacturers that currently build Chromebooks. Google is branding premium devices as Googlebooks , positioning them as direct competitors to MacBooks and premium Windows laptops.

Devices will span multiple tiers: “AL Entry” for budget education devices, “AL Mass Premium” for mainstream consumers, and “AL Premium” for high-end professional users. Form factors include traditional laptops, detachables (tablet-laptop hybrids), tablets, and mini-desktop boxes (like current Chromeboxes).
