What is KAMUI OS? A Deep Dive into Japan's ”AI-Native OS” [Latest Info for 2025]

The era in which AI becomes an “operating system” has finally arrived. KAMUI OS—Japan’s groundbreaking AI-native OS—is poised to redefine how we interact with our digital environment. This article breaks down how KAMUI OS works, what makes it unique, and why it has drawn significant attention both in Japan and overseas.

KAMUI OS: Japan’s AI-Native Operating System Designed to Coexist with Users

AI has already become deeply woven into our everyday lives. Whether it’s writing documents, organizing schedules, or searching for information, “letting AI handle it” has become the new normal in recent years.

But now, AI is taking an unprecedented step forward— it is becoming the operating system itself. Not an app, not a tool, but an entity that understands, navigates, and executes everything across your digital environment.

This is Japan's revolutionary AI OS.KAMUI OS.

It’s more than a “convenient AI.” It embodies the idea of becoming your personal digital partner.

Honestly, seeing this public information sent shivers down my spine. I never imagined AI would reach the OS level. The world is changing—I felt like I was witnessing that very moment.

In this article,KAMUI OS: How it works, its potential, and why it’s gaining global attention — a deep dive into “What exactly is an AI OS?” explained in a way anyone can understandWe will proceed.

This section provides the first entry point into the concept of an AI OS. From here, we will explore why KAMUI OS is drawing global attention.

KAMUI OS is a new AI-native OS concept developed by Japan’s Hastings Corporation. Its defining strength lies in its ability to fully understand what users are working on across multiple applications, enabling operation entirely through voice and natural language.

Instead of the traditional workflow— launching an app → selecting a menu → performing tasks —KAMUI OS allows AI to take over the entire process by understanding the task itself and executing it autonomously.

Internationally, AI-driven systems such as Rabbit OS and the Humane Ai Pin are beginning to appear. However, KAMUI OS stands out as a software-based AI OS, requiring no dedicated hardware and running directly on Mac and Windows.

In other words,Your own computer evolves into an AI OS without the need to purchase any dedicated device.This is the concept.

The concept behind its development is simple yet bold:
“An OS that understands your entire digital life and acts as your personal companion.”
The goal is a future where everyday tasks—email, scheduling, information gathering, document creation, and even app operation—can all be delegated to a single, unified AI system.

As of 2025, the price for the Pro plan has been announced at ¥2,000 per month, and the OS is currently being rolled out gradually to beta testers. Although many details remain undisclosed due to its pre-release status, KAMUI OS has already become a next-generation OS attracting significant interest within the global AI community.

What's New: Why KAMUI OS Is Gaining Global Attention

The primary reason KAMUI OS is attracting attention is thatAI is now advancing into the OS layermarking a major turning point in technological evolution.

Until now, AI has existed merely as another app—a tool for writing text, assisting with searches, or streamlining simple tasks. Each required the user to adapt their workflow to the tool.

KAMUI OS takes a completely different approach.

Here, AI becomes the central operator, understanding the user’s intent and performing the necessary actions across applications on their behalf.

This reflects a level of conceptual depth that sets KAMUI OS apart from conventional AI tools.

1｜A Global Shift Toward “AI OS” Is Accelerating

KAMUI OS is not an isolated innovation—the entire world is moving toward the concept of an AI-driven operating system. Examples include:

• Rabbit OS (R1) — A hardware device where AI performs app operations
• Humane Ai Pin — A wearable AI device controlled through voice and gestures
• Microsoft Copilot — AI becoming deeply integrated into the Windows ecosystem
• Apple Intelligence — AI features becoming standard on iPhones and Macs

All share the same direction:AI will take center stage in digital operations,and that is the global trend.

What makes KAMUI OS stand out is its hardware-independent design. It runs directly on existing PCs without requiring dedicated devices—an approach that remains uncommon worldwide.

2｜A System Designed to Transcend App Boundaries

Traditional AI was limited to operating inside individual applications. However, KAMUI OSis designed on the premise of crossing app boundaries,enabling AI to move beyond conventional app constraints…

AI is designed to autonomously handle multi-application workflows—such as extracting figures from emails, entering them into spreadsheets, generating documents, and integrating them into schedules.

This marks a fundamental shift that elevates AI from a simple tool to an operating system, which is why it has drawn significant attention from AI researchers worldwide.

3｜An Unprecedented Presence as a Japan-Born AI OS

The AI OS landscape is typically dominated by large American and Chinese tech companies. In this context, the announcement of an AI OS by a Japanese startup itself became major news.

Creating an OS-level experience solely through software is rare among Japanese products, and KAMUI OS has been widely discussed in international tech communities and forums.

4｜A Novel Concept: “Understanding the User’s Entire Digital Life”

KAMUI OS abandons the traditional idea of “launching apps.” Instead, it proposes a future-oriented operating system in which AI understands the user’s intent—what they want to accomplish—and performs the required operations automatically.

This concept aligns with what is known overseas as an “Agentic OS,” a cutting-edge topic being explored as the next frontier of operating systems.

5｜Establishing Its Market Position as “AI That Becomes the OS”

Although many AI tools exist today, most function merely as features within individual apps.

In contrast, KAMUI OS has positioned itself from the start as “AI that becomes the OS.” This has gained significant attention not as marketing hype, but because it genuinely aims to understand and execute tasks at the OS level.

【──Summary So Far】

KAMUI OS is gaining attention not simply because it is a new AI tool, but because it represents the concept of an “AI OS” that could reshape the direction of technology itself. It stands as the first step toward the next stage of digital innovation.

In the next section, we’ll clearly break down what KAMUI OS can actually do.

List of What You Can Do with KAMUI OS

KAMUI OS is built on the premise thatAI operates as an actual OS layer,a concept that differentiates it from conventional AI applications. Here, we outline the key capabilities of KAMUI OS based on publicly available information as of December 2025.

1｜App Operation Assistance

When users describe what they want to accomplish, the AI identifies the necessary applications and performs the operations on their behalf.

Example: Extract information from an email → Enter it into a spreadsheet → Generate related materials, and more.

2｜Cross-Task Processing

The AI autonomously handles multi-app tasks that span various services, all toward a single objective. This structure eliminates the need for users to manually work within each app.

3｜Voice and Natural Language Control

Instead of relying on keyboard or mouse input, you can issue OS-level commands simply by speaking or expressing your intent. There is no need to articulate your workflow step-by-step—just tell the system what you want done.

4｜Organizing and Summarizing Information

The system aggregates information from emails, memos, web pages, PDFs, and other sources, organizing the content and extracting key points. It is designed to ease the burden of everyday information management.

5｜Automating Schedule Management

AI handles data acquisition, updates, and adjustments. It can interpret content and link it to relevant tasks or document creation.

6｜Content Production Assistance

AI provides cross-functional support for creative work such as drafting manuscripts, generating outlines, and preparing materials. It is designed to handle multi-step production workflows that span different apps (writing → images → sharing).

7｜Understanding Purpose-Driven Behavior

The key feature is that the system understands and executes what you want to achieve, not how to operate the app. This reflects an OS-level philosophy not found in traditional AI applications.

【──Summary So Far】

The features of KAMUI OS are:AI moves beyond app boundaries and assembles tasks based on your intended purpose.The key point is that it’s not merely a convenient AI—it’s designed to deliver an entirely new OS experience.

Next, we'll explain how KAMUI OS is provided—specifically, its operational model (an AI platform closely integrated with the OS).

Operating Model: An “AI platform that functions closer to an OS” rather than a traditional app

KAMUI OS is not an AI application, but is designed as an ”AI platform closer to an OS.” This is the most significant difference from other AI services.

First, it's important to understand thatKAMUI OS does not require any dedicated devices or proprietary hardware.In other words, it runs on your existing Mac or Windows PC.

In other words, you don't need to buy new gadgets to use KAMUI OS. This is a major difference from hardware-based AI like Rabbit OS or Humane Ai Pin.

1｜The concept of adding ”OS-layer AI” to existing PCs
KAMUI OS is designed to run on top of conventional operating systems (macOS/Windows), with AI operating as a resident layer. By integrating AI at a level closer to OS operations and system management—rather than as a standalone app—it enables multi-application task processing.

2｜Cloud-based AI processing
KAMUI OS processes AI tasks in the cloud, making it far less dependent on local hardware performance. Because there's no need to install large AI models on your PC, the system remains accessible and lightweight for general users.

3｜Diminishing the concept of ”launching” an app
Traditional operating systems require users to launch apps before working. KAMUI OS shifts away from that model, aiming for an “app-invisible experience.” It automatically calls the necessary apps based on the user’s intent and executes operations in the background.

4｜The axis of operation shifts from "clicks" to "intent and purpose"
With KAMUI OS, users simply express what they want to accomplish, and the system handles everything else. The AI determines the optimal steps and executes the task via the shortest and most efficient route.

5｜UI/UX Design with ”AI as an OS” in Mind
Based on currently available information, KAMUI OS is implemented not as a conventional app window but as an AI entity that resides within the OS. Integration with OS-level functions—such as notifications, task management, and data access—is built into its core design philosophy.

【──Summary So Far】

KAMUI OS is not an AI app—it is an AI platform that understands your tasks at the OS level and performs required operations on your behalf.It is designed to free users from manually opening and closing apps, offering a new OS experience where “digital tasks progress simply by stating your intent.”

Next, we'll summarize the currently available information regarding KAMUI OS, including its price and release date.

【──Summary So Far】

KAMUI OS is designed not just to save time on individual tasks, but to optimize overall workflow efficiency. In particular,The more you switch between multiple apps for your work, the greater the benefit.This is a product.

Next, we'll compare KAMUI OS with ”world-class AI operating systems” to clarify what makes it unique.

Comparison with AI Operating Systems Worldwide

To understand KAMUI OS’s position, we compare it with major publicly available “AI OS” solutions (or AI devices) as of today. This comparison is based strictly on factual information.

【Key Points】
・The overseas market is increasingly polarized between device-based solutions (Rabbit, Humane) and OS-integrated solutions (Microsoft, Apple).
・KAMUI OS occupies a unique position as an "AI OS that runs on PCs," belonging to neither category.
・Its unique appeal lies in the ability to ”AI OS-ize” existing PCs without requiring new hardware purchases.

KAMUI OS occupies a unique position distinct from both ”device-based AI” like Rabbit OS and “integrated AI” like Microsoft or Apple.

In other words, it’s not about “people who use AI,” but—“AI resides as the OS, comprehending and executing tasks across the entire system.”The key feature is that it aims to provide this experience within your existing PC environment.

Current Challenges

KAMUI OS will still be in beta as of 2025, and much of the publicly available information remains “unconfirmed.” In this section, we summarize only what has been factually established.
