For years there has been talk that Google would end uniting Android and ChromeOS into a single platformBut until recently, it was all just rumors and failed projects like Andromeda. Now, various leaks and internal job postings have revealed the codename for the company's most ambitious move in the PC world: Aluminium OS, an Android-based system that directly targets Windows and macOS.
This new development is not a simple update or a laboratory experiment, but a serious attempt to Rethink the future of ChromeOS and bring Android to the desktop legally.We're talking about a platform designed for laptops, desktops, tablets, and mini PCs, with the Gemini artificial intelligence At the heart of the experience, full support for Android apps and an interface truly adapted for use with keyboard, mouse and large screens.
What is Aluminium OS and what is its role compared to ChromeOS and Android?
Aluminium OS is the internal name Google is using for its new desktop operating system built on the foundation of AndroidUnlike previous attempts to bring Android to PCs through custom skins or special modes, this time the company is designing the platform from scratch with x86 computers in mind, and presumably also next-generation ARM processors.
While ChromeOS was born as an ultralight environment focused on the browser and cloud applications, Aluminium OS is positioned as a system much closer to Windows or macOS, with a focus on local applications, true multitasking with free windows and deep integration with the Android ecosystem and Google AI.
The leaked documents refer to Aluminium OS as a system intended to run on traditional PCsand not limited to just Chromebooks or cheap laptops. The goal is to cover everything from entry-level to high-end devices, something that ChromeOS, despite its progress, has never quite managed to achieve in the mainstream market.
Android, for its part, will remain the dominant platform in mobile phones and tablets, but Google intends that increasingly share components and architecture with Aluminium OSIn fact, ChromeOS has been using parts of the Android stack (kernel, frameworks) and mobile app support for years, a path that is now being accelerated with this new initiative.
The project aligns with statements from executives like Rick Osterloh and Sameer Samat, who have confirmed at various events that Google is working on a “single platform” that combines the best of Android and ChromeOS, with artificial intelligence as the main focus.
Brief timeline: from Andromeda to the Android + ChromeOS merger
The story of Aluminium OS doesn't start from scratch: it's been almost a decade since Google is flirting with the idea of merging Android with its desktop ecosystemBack in 2015, there was strong talk of a project called Andromeda that never materialized commercially.
Over the past few years, ChromeOS has been incorporating key components of the Android stack, such as the Android Linux kernel and different frameworks, in addition to allowing the installation and running of mobile applications through Google Play on many Chromebooks.
This move paved the way for greater convergence. In 2024 and 2025, with Android 15 and Android 16, we began to see a Android desktop mode is becoming increasingly capablewith floating windows, improved external display management, and specific productivity features.
Meanwhile, Google and Qualcomm announced at the Snapdragon Summit that they were working to Bringing Android natively to PCTaking advantage of high-performance ARM chips like the Snapdragon X Elite and later. In that context, Sameer Samat clearly spoke of the intention to unify Android and ChromeOS into a single platform.
The missing piece came with the job postings leaked by outlets like Android Authority, where a “New Android operating system called Aluminium”, built with artificial intelligence as a starting point and geared towards laptops, tablets and other desktop formats.
Architecture and main objectives of Aluminium OS
According to available information, Aluminium OS is based on Android, but not as a simple visual layer, but as a complete desktop system supported by the Android ecosystemThis includes native compatibility with mobile apps, full access to Google Play, and a redesigned experience for working with a mouse and keyboard.
One of the key objectives is to stop maintaining two parallel development lines (Android and ChromeOS) to concentrate resources on a single scalable platform, capable of running on mobile phones, computers, tablets, and mini PCs. The idea is somewhat reminiscent of what Apple has done with iOS and iPadOS, but on a much larger scale.
In contrast to ChromeOS's cloud-centric approach, Aluminium OS is more oriented towards local applications, advanced productivity, and intensive use of AIwithout sacrificing the benefits of online synchronization and Google services. Compatibility with powerful ARM chips and modern x86 CPUs will allow for better hardware utilization.
Internal documents and job postings reveal a clear hardware segmentation: categories such as “AL Entry”, “AL Mass Premium” and “AL Premium” They define everything from budget devices to high-end machines capable of competing with a MacBook Pro or a thin gaming laptop.
In terms of timing, various leaks suggest that the first devices with Aluminium OS could arrive in 2026, probably based on Android 17Until then, the platform will continue to be developed and undergo internal testing on different hardware configurations.
Window management and true desktop experience
One of the major weaknesses of Android on the desktop has always been its limited and unnatural window management To work with multiple apps open at once, Aluminium OS aims to solve this problem with an interface designed from the ground up for PCs.
Leaks indicate that the system will include fully resizable windowswithout the typical restrictions of mobile split-screen viewing. This will allow you to place multiple applications in different areas of the monitor, as in Windows or macOS, and comfortably work on several tasks simultaneously.
There is also talk of a persistent desktop modeThis functionality doesn't disappear or change abruptly when you disconnect an external screen or rotate the device. The experience will be that of a conventional desktop system, not a mobile device with a clunky interface.
Furthermore, the organization of multitasking is thoroughly reviewed to make it possible Run multiple Android apps in parallel without limitations current features from many launchers and manufacturer skins. The goal is to create a "real" Android experience for productivity, without relying on custom skins from each brand.
This approach makes Aluminium OS a real alternative to solutions like the Android subsystem on Windows or emulators like BlueStackssince the apps would run natively, with better performance and full integration with the system.
AI integrated at the core: Gemini as the backbone
If ChromeOS was the "everything in the browser" system, Aluminium OS wants to be the system “AI First” with artificial intelligence involved in every aspect of lifeJob postings and internal documents literally refer to AI as the core of the operating system.
Google intends to integrate Their Gemini models directly on the base of Aluminium OSnot just as another app or a floating assistant. This opens the door to contextual assistants that understand what you're doing at any given moment and suggest actions, summaries, or automations without you having to explicitly ask.
The functions being considered include content generation within applications (text, images, or even code), proactive suggestions based on your usage, real-time translation, advanced speech recognition, and smart tools for professional tasks.
The key is that many of these capabilities will be able to be executed locally thanks to the latest generation CPU, GPU and NPUespecially in devices from the “AL Mass Premium” and “AL Premium” ranges. This reduces reliance on the cloud, improves privacy, and allows for much faster responses. For those who need it, there is a mode to Disable Gemini on Android.
This commitment to AI integrated from the ground up differentiates Aluminium OS from both Windows and macOS, where AI is still perceived more as an additional layer, and from ChromeOS itself, which was never conceived as a platform with AI at the center of its design.
Full compatibility with Android apps: the system's greatest strength
Another of the pillars of Aluminium OS will be its Native compatibility with the entire Android app ecosystemInstead of relying on isolated containers or external subsystems, the system will run mobile apps as first-class citizens within the desktop.
This means that users will have full access to Google Playwith the same account and app library as on your mobile phone or tablet. The difference is that these apps can be opened in separate windows, with support for keyboard, mouse, shortcuts, and large screens.
The experience promises to be much smoother than traditional emulators: being based directly on Android, Aluminium OS It avoids many of the compatibility layers. that hinder performance on Windows or macOS when using third-party solutions.
For developers, the proposal is very attractive: with a single ecosystem (Android + Aluminium OS), it will be simpler. create applications that work on both mobile phones and computersadapting the interface according to the type of device without rewriting everything for another platform.
In this sense, Google wants to leverage its The strategic advantage of having millions of apps and a huge developer communitySomething that neither Windows nor macOS can match in the mobile arena, and bringing it to the desktop with a much more natural integration than previous attempts, further supported by agreements such as the deal with Epic Games.

Target hardware: from budget Chromebooks to premium models
ChromeOS gained strength primarily in the education sector and in low-cost laptops geared towards simple tasks, such as web browsing or basic office applications. Aluminium OS was born with another ambition: to encompass everything from affordable devices to very powerful machines capable of running complex AI models.
The leaked internal documents and roadmaps clearly mention segments such as “AL Entry”, “AL Mass Premium” and “AL Premium”The first ones target laptops and budget devices, probably replacing part of the current Chromebook catalog.
The “AL Mass Premium” and “AL Premium” categories focus on high-end laptops, desktops, mini PCs and advanced tabletswith modern processors and integrated or dedicated GPUs capable of rivaling Windows or Mac machines.
Among the test hardware mentioned are processors such as MediaTek Kompanio 520 and Intel's 12th generation Alder LakeThis indicates an intention to support contemporary x86 architectures and dedicated AI-optimized ARM platforms.
Furthermore, various reports point to a close collaboration with Qualcomm to optimize Aluminium OS on the new Snapdragon X chips and future models, which promise ARM performance on par with Intel and AMD CPUs, and highly capable integrated GPUs for graphics and AI computing.
Relationship with ChromeOS: coexistence, transition and possible replacement
The big question for many users is what will happen to ChromeOS and current Chromebooks. Leaked job postings indicate that the position is focused on to advance the ChromeOS and Aluminium OS roadmaps simultaneouslyfor laptops, tablets and mini PCs (including Chromeboxes).
Everything points to a period of coexistence between both operating systems...at least for several years. ChromeOS will continue to receive support and updates, especially in the educational environment and on low-cost devices, while Aluminium OS gains ground in new ranges and form factors.
However, the internal documentation also mentions the need to design a transition strategy from ChromeOS to the new Aluminium OSThis aligns with other leaks where internally they are already referring to the current system as "ChromeOS Classic".
It is very likely that some relatively recent Chromebooks, especially those with modern hardware (12th generation Intel, certain Kompanio, etc.), may receive an optional upgrade to Aluminium OS in the future, provided the experience remains stable.
In any case, Google is aware that It cannot abandon millions of users and educational centers overnight.Therefore, the transition will be gradual and with extended support for existing devices, avoiding abrupt disruptions as has occurred in other platform changes in the industry.
Key differences between Aluminum OS, ChromeOS and Android
If we compare the three platforms, clear differences emerge. ChromeOS is a system born for work almost all the time in the cloudwith the browser as the main focus and local apps in the background, although with growing support for Android and Linux.
Android, on the other hand, was designed from the ground up to mobile phones and tablets with touch screenOptimized for gestures, full-screen apps, and content consumption. Its desktop mode, although improved, remains an add-on, not the main focus.
Aluminium OS wants to combine both worlds, but with a different philosophy: starting from the Android universe to create a complete desktop system, with core AI and interfaces adapted to keyboard and mouse, without sacrificing compatibility with mobile applications.
Compared to Windows and macOS, Aluminium OS differs primarily in two aspects: it relies on a gigantic mobile ecosystem that already exists (Android apps) and conceives of artificial intelligence as part of the system from minute one, not as a later addition, as shown by movements where Apple and Google are moving closer to an agreement.
Where it does resemble its rivals is in its ambition to reach all product ranges, from basic equipment to professional modelswith a single platform adaptable to different formats: laptops, desktops, convertibles, tablets and mini PCs.
Everything that has been leaked about Aluminium OS paints a picture of a very ambitious project that Google wants Breaking down the historical barrier between mobile phones, Chromebooks, and traditional PCsLeveraging Android, the strength of its app ecosystem, and Gemini as its AI engine, if the company manages to execute the transition from ChromeOS successfully and deliver a robust desktop experience with good window management, broad hardware compatibility, and truly useful AI for everyday use, this new system is likely to become its most serious attempt yet to compete with Windows and macOS in the personal computer market.
