Create an account
Sign up with email, Google or GitHub. You get a personal workspace on the Free plan, with no card needed.
2
Describe your app
On your workspace home, type what you want in plain words and press Enter. Say who it’s for, the main screens, and how it should feel. For example:
- “A habit tracker where every streak grows a little garden. Soft greens, big friendly buttons.”
- “A menu and loyalty card for my coffee shop, with a stamp for every tenth latte.”

Watch it build
The agent writes the code in its own cloud sandbox, and the chat shows what it’s doing. When it finishes, every change is typechecked and bundled for Android. A change that passes becomes a working version.If the checks fail, the agent first tries to fix its own errors. If it can’t, the version is saved as broken, with the errors attached, so you can fix it with AI or roll back.

Try it
The preview panel runs your app in the browser as soon as it’s ready. To hold it in your hand, open it on your phone with Expo Go. See Preview on your phone.

Keep going
Send another message to change anything: “make the buttons bigger”, “add a settings screen”. Each message that changes the app saves a new version you can always go back to.
