Create an account
Sign up with an email address and a password, or with Google. Email sign-up sends a verification link; you have to open it before you can sign in.
A new account receives welcome credits and 5 build credits every day, which reset at 00:00 UTC.
Describe your app
On the home page or your dashboard, write a few sentences: what the app does, who uses it, and the two or three screens you expect. Choose a build target — web, iPhone, Android or game — and, if you like, a design style.
If you write a prompt while signed out, it follows you through sign-up and lands in the builder automatically.
Refine in conversation
The builder shows the conversation on one side and a live preview on the other. Ask for one change at a time and check the preview after each one.
Every build message shows what it cost in credits once it finishes.
Generation calls a language model. Until a model provider key is configured for this installation, build messages stop with a clear notice and no credits are charged.
