Aluminum OS: What we know about Google’s next operating system

Despite Android’s presence in almost every sector of the tech industry, it has yet to truly gain a foothold on PC platforms. Google has been using ChromeOS to power Chromebooks for years, but Android’s ubiquity — coupled with its lack of a significant presence in traditional computing — made it clear that something had to give.

Google is now moving to unify ChromeOS and Android into a single desktop platform, currently operating under the codename “Aluminum OS.” (Or, depending on who you ask, Aluminum OS.)

What is Aluminum OS?

As far as we know – thanks to reporting from Android Authority – Aluminum OS is the internal codename for Google’s unified Android/ChromeOS desktop platform. The merger was officially announced last September at Qualcomm’s Snapdragon Summit, although rumors of a ChromeOS-Android convergence had been circulating for at least a year.

In that September announcement, Google said it would partner with Qualcomm to develop a new platform integrating mobile and desktop computing, powered by the latest advances in AI.

The name “Aluminum OS” comes from a tip shared with Android Authority, which led the outlet to a now-deleted Google job posting for a senior product manager in Taipei City, Taiwan. Luckily, Archive.today captured the post before it disappeared. In it, Google states that it is “working on a new Aluminum operating system, based on Android” and that “Aluminium is a new operating system built with artificial intelligence (AI) at the heart.”

The role also mentions “driving the roadmap and curating a portfolio of commercial ChromeOS and Aluminum Operating System (ALOS) devices across all form factors (e.g. laptops, detachables, tablets, and enclosures).” In other words, Aluminum OS won’t be limited to laptops. Tablets and so-called “boxes” – which Android Authority interprets as budget-type machines, such as Chromebooks or even Mac Mini-like devices – are also part of the plan.

A number of leaks after September have given us an even clearer idea of ​​what to expect from Aluminum OS.

In May, MysticLeaks released a 16-minute video purportedly showing the process of setting up the new operating system (running on a virtual machine inside a MacBook). In the video you can see that the interface looks quite similar to what is already available in ChromeOS, although there is a few differences. Applications can be placed on the desktop and you can right-click to create new folders, to the Windows, for example.

It also has an Android-style Quick Settings menu and a task manager, but there’s not much else to glean from the video.

Besides the unofficial leaks, we believe Google also made an indirect reference to Aluminum OS during The Android Show livestream event on May 12.

While previous reports indicated that Aluminum OS may run on a variety of device categories, it appears that it could debut with Googlebooks, a new class of laptops announced by Google a week before Google I/O 2026. Google has only briefly teased Googlebooks so far, but if Aluminum were to work on anything, it would most likely work on one of these laptops.

In fact, Google’s posts about Google Books all but confirm this. In the initial reveal, Google talked about Googlebooks as if they would somehow be a successor to Chromebooks, leveraging Android apps as well as Gemini. Users will be able to use AI to generate widgets.

Here’s how Google described the Googlebook experience:

With the shift from operating system to intelligence system, we felt it was time for another fundamental reinvention. This year, we’re taking the best of Android, a modern operating system with powerful apps on Google Play, and the best of Chrome OS, which comes with the world’s most popular browser and largest library of extensions. And now they’re bringing them together, creating a new category of laptops built with Gemini at the heart, working seamlessly with the devices in your life, and powered by premium hardware. Discover Googlebook.

This could very well be our first official look at Aluminum OS’s capabilities.

Google showed off several unique features of Googlebooks, such as the ability to open Android apps from your phone directly on your laptop without downloading the app.

They also revealed the “Magic Pointer,” an AI-powered pointer update. You’ll be able to hover over any element on the screen and get AI suggestions for next steps, more information, and other options.

We expect Google to tell us more about Googlebooks, and by extension Aluminum OS, in the very near future.
