PALMAGINE - Build Apps

"I wish there were an app for that."

Now you can build it the moment you think of it — with nothing but the phone in your hand. No computer. No development environment to set up.

PALMAGINE lets you build apps by talking with an AI, then run them right there on your phone.


■ Just say it, and the code gets written

"Make me a habit tracker." "Switch it to light mode, colorful and playful."

Say it in your own words, and the AI agent writes the code and edits the files. You can start without knowing how to program — and you can always open the code and see exactly what was written.

Works with Claude, GPT, and Gemini (bring your own API key).


■ Run it and see it, right where you wrote it

Whatever you build starts up inside this device. No cable, no transferring builds to a test phone.

Not quite what you pictured? Just say the next thing. Try it, fix it, try again — the whole loop takes seconds.


■ That idea you had on the train becomes something real

On the train, on a break, lying in bed. The ideas that used to fade away before you got to a computer can take shape right now.


■ The code you write is genuinely yours

It connects directly to your GitHub repositories. What you build stays in your own account — pick it up on a computer later, or publish it. Nothing is locked away.

The Code tab includes a syntax-highlighted editor, so you can make edits by hand too.


■ What you can build

Runs instantly on your device
・React (React Native / react-native-web)
・Vue 3 (single-file components)
・Web apps (HTML / CSS / JavaScript)

Built in the cloud with GitHub Actions
・Flutter
・React Native (Expo)


■ Who it's for

・People with ideas but not much time to sit at a computer
・Anyone learning to program who wants to see something actually run
・Commuters and anyone with waiting time to turn into making time
・Anyone curious about AI coding who got stuck setting up a toolchain


■ Before you start

・You'll need your own API key from Anthropic, OpenAI, or Google. Keys are stored encrypted on your device and are never sent to our servers.
・A GitHub account is required to sync your repositories.
・Available in English, Japanese, German, French, Spanish, and more.


A development environment, in the palm of your hand.
