Every era needs its OS for your phone

Open source · Research Preview

We're an operating system company building for an era when AI is simply how computers work.

The OS for your “I wish it could…” moments.

Taku OS is designed to make every layer of your device customizable—from the interface and apps to hardware and core system behavior.

Developer videoComing soon

One layer for everything your agent needs.

The Feed brings your context, commands, actions, and capabilities together in one agent layer. It moves you from opening apps to getting things done.

  1. Apps appear as live cards, each in its own design. When the agent makes a suggestion, it returns to the conversation, ready for a one-tap response.

  2. Tap the voice input at the bottom of the screen and say what you need. Hold the side button to keep the conversation going. Go Live to talk in real time while you continue using your phone.

  3. No more digging through menus. Ask the agent to change themes, layouts, and supported system settings. Ask again to change them back.

Your agent works across apps, the way you would.

Most phone assistants live inside one app and wait for a question. In Taku OS, the agent can use supported system capabilities directly, allowing a task to move across your apps.

01Background windowsApps run in their own background windows, so the agent can work while you keep using your phone.
02System-level interactionThe agent interacts with apps through the system, including apps you already use.
03Direct capabilitiesWhere an app exposes a capability directly, the agent can access and use it.

Your hardware, open to your code.

Camera, microphone, Wi-Fi, Bluetooth, and motion sensors are accessible through supported interfaces, alongside the devices you connect.

  1. On the deviceUse the camera, microphone, and sensors from your code or through the agent. Availability depends on the device, drivers, and permissions.
  2. Around the deviceConnect earbuds, lights, and other devices, and control them from one place.

Change how the system itself behaves.

Core system behavior isn't off limits. Taku OS is open source, so you can explore the system code, understand how it works, and change it.

Research PreviewTaku OS is in an early stage of development and intended for testing and development. It isn't recommended for work use.

Get started.

Prepare your device, let your coding agent guide the setup, then start exploring and building.

  1. 01

    Choose how to try Taku OS

    On a phone

    You'll need a computer, a supported phone, and a USB cable that supports data transfer. Pixel 9 is recommended. Back up your phone before you begin.

    Coming soon

    In an emulator

    Don't have a compatible phone? Run an Android ARM64 virtual device on your computer and leave your phone untouched.

    Coming soon
  2. 02

    Let your coding agent guide the setup

    Paste this into Claude Code, Codex, or another coding agent. Follow its instructions and confirm any steps that require your approval.

    Coming soon
    Read https://github.com/Taku-OS/taku-os/blob/main/docs/agent-setup.md and set up Taku OS for me on my phone or in the emulator.
  3. 03

    Connect a model and start exploring

    Once Taku OS starts, sign in and choose a model. Use your own API key or sign in with your ChatGPT subscription.

  4. 04

    Make it your own

    Change the system code directly, or start by building your first plugin.

AI belongs in the OS.
The OS belongs to you.

AI is becoming a natural part of how we use computers. To be useful, it needs to reach across the system—not stay inside a single app. And something that runs this deep should be open, so anyone can inspect it, change it, and build on it.
