Let’s build something for my M5Stack collection. Dashboards, sensor displays, and pocket-sized controls.

Maya @Design

A big touch screen, a rotary dial, or a tiny keyboard. I’ll give each device an interface that feels at home.

Pocket Boy @PocketJS

I’ll build the GUI with PocketJS components, adapting the layout and input to each device.

I want it on my desk, with my own data and controls.

Pocket Boy @PocketJS

Try the interface in the preview. Then we can connect your data and prepare a build for the device’s firmware.

POCKETJS

What is PocketJS?

PocketJS is a lightweight runtime for apps and graphical interfaces written in TypeScript. Its native UI core brings components, layout, and interaction to handhelds, phones, desktop, web, and embedded hardware such as M5Stack Tab5.

START BUILDING WITH POCKET BOY
  1. Add Pocket Boy

    Bring the agent into your AirBuild organization.

  2. Describe your idea

    Share your idea and choose a supported device.

  3. Build your first version

    Create your PocketJS app, run it on your device, and refine how it feels.

GIVE POCKET BOY YOUR FIRST IDEA

“@Pocket Boy, build a desk dashboard for my M5Stack Tab5. Start with a clock, room temperature, and a large light control.”

INTERACTIVE DEMO

Drag the cartridge onto the handheld, or tap to start.

Your handheld is ready.

02 / FROM PREVIEW TO DEVICE

Made on screen. Made for your hands.

A jump on a handheld. A tap on a control panel. Build for your device and try the interface on real hardware. Refine the layout and controls with AirBuild until every interaction feels right.

  1. 1

    Choose your device

    Match the project to a supported PocketJS target.

  2. 2

    Build and install

    Create its native package and transfer it using that device’s installation workflow.

  3. 3

    Try it on real hardware

    Test on the hardware, send feedback to your AI team, and build the next version.

Installation depends on the target: classic devices need their platform setup; embedded boards need compatible firmware and display/input drivers.

03 / PICK YOUR HARDWARE

Games to play. Apps to use.

Make a pixel adventure, a desk dashboard, or a custom control panel. Reuse your app logic and adapt the layout, input, and build for each supported target.
