Build iOS and Android apps from your phone.

Zusagi is an AI mobile app builder. Describe the app you want and it generates the screens, navigation, state, backend, authentication and database, then lets you preview the result on the same phone you built it from.

Start building How it works

Zusagi generating a mobile fitness app on a phone

Everything a mobile app needs, generated together.

Screens and navigation

Onboarding, lists, detail views, tabs, modals and forms generated from your description.

iOS and Android

One project targets both platforms with native-ready mobile code.

Authentication

Sign-up, login, sessions and password reset wired to your backend.

Data and APIs

A database schema and the APIs your screens call, generated to match.

Payments and integrations

Connect subscriptions, notifications and third-party services when your app needs them.

Preview and fixes

Run the app on your phone, describe what to change, and Zusagi patches it.

Workflow

From prompt to a running mobile app.

A typical mobile build follows four steps. Each one happens in the Zusagi chat, on your phone.

Describe the app
For example: a habit tracker with accounts, reminders and a weekly dashboard.
Review the plan
Zusagi proposes screens, the data model and the backend. Adjust anything in plain language.
Generate and preview
The app is built and opened as a live preview on your phone.
Iterate and publish
Request changes, fix issues and publish your build when it is ready.
