Every layer of your app, built by AI.

Zusagi plans, generates, previews, fixes and deploys mobile apps, websites, frontends and backends. Each capability below works from a phone, without a computer.

Mobile

AI Mobile App Builder

Describe a mobile app and Zusagi generates the screens, navigation, state management and the backend it needs, ready for iOS and Android.

  • Screens, navigation and forms generated from your description

Full stack

AI Full Stack App Builder

Frontend, backend and database are planned together, so the pieces fit from the first build instead of being stitched together later.

  • One coherent architecture per project
  • Shared types between client and server
  • End-to-end features generated in a single request
  • Deployment of the whole stack

Mobile coding

Mobile Coding with AI

Write, read, review and fix code from a phone. Zusagi replaces the terminal, IDE and build machine with a conversation.

  • No laptop, IDE or terminal required
  • Ask for changes and review the diff
  • Automatic fixes when a build or preview fails
  • Full project management from mobile

Phone-first

AI App Development from Phone

The complete lifecycle, from first prompt to deployed application, happens on a mobile device.

See how it works
  • Create and manage projects
  • Generate, preview and deploy
  • Works wherever you are
  • Designed for touch, not adapted from desktop

Prototypes

AI Prototype Generator

Turn an idea into a working, clickable prototype in one session, then keep building on the same project when it is validated.

  • Working prototypes, not mockups
  • Real data and real navigation
  • Share a live preview
  • Grow the prototype into the product

Start with a prompt. End with a deployed app.
