A practical guide to building an app with AI: from writing a clear description to planning, generation, preview, fixes and deployment.

Start with a description, not a wireframe

AI app builders work from language. The better you describe the users, the core actions and the data your app stores, the better the plan you get back. A useful description names the audience ("small gyms"), the key objects ("members, classes, bookings") and the moments that matter ("a member books a class and gets a reminder").

You do not need technical vocabulary. Zusagi translates a plain description into an architecture: screens, a data model, APIs and integrations.

Review the plan before anything is generated

Good AI builders show you the plan first. Read the list of screens and the data model. If a screen is missing or an entity is wrong, say so in one sentence. Fixing a plan takes seconds; fixing a generated app takes longer.

In Zusagi this happens in the same chat where you described the idea, and it works from a phone.

Generate, preview, then iterate

Once the plan is approved, frontend, backend and database are generated together. Open the preview, use the app as a real user would, and describe what feels wrong. Each request becomes a targeted fix instead of a rebuild.

Expect three to five rounds of feedback for a first version. This is normal and much faster than a traditional build.

Deploy when it works

Deployment should be one action, not a weekend of configuration. On Zusagi, Pro and Max plans publish the whole stack. Share the link, collect feedback, and keep iterating in the same project.
