# Build your first app

Describe your idea in chat and watch Evonx scaffold a working web app and API in minutes. No code required.

In about ten minutes, you'll go from a one-sentence idea to a real, running
application — a web app for your users and an API with its own database behind it.
You don't need to write any code.

We'll build a working example you can follow along with: **Garage Usta**, a small
auto-service shop that wants to track vehicles, customers, and repair jobs.

> **Note**
> You need an Evonx account and a business workspace. If you don't have one yet, start
> with [Create your account & workspace](/docs/get-started/create-your-account).

## Describe your idea

1. Open your business and start a new chat from the home screen.

2. Describe what you want in plain language. Be specific about who uses the app and
   what they need to do:

   > I run an auto-service shop. I need an app where my staff can register customer
   > vehicles, open repair jobs with notes and photos, track job status, and see a
   > daily overview of the workshop.

3. Send the message. Evonx analyzes your request and decides how to build it — for a
   custom idea like this one, it creates a **greenfield custom project**: a web
   application for your staff and a separate API project with its own database.

> **Tip**
> The more concrete your first message, the better the first version. Name the people
> who will use the app ("my staff", "my customers") and the three or four things they
> must be able to do. See [Effective prompting on Evonx](/docs/evolve/effective-prompting)
> for examples.

## Watch the scaffold come to life

Evonx now creates two repositories inside your business — one ending in `-web` (the
user interface) and one in `-api` (the backend and database) — and generates the
first version of your app in them: screens, data model, and seed data that match
your description.

You can follow the progress in the chat. When scaffolding finishes, Evonx suggests
the next steps as action cards — the most important one is starting a live preview.

## Check your work

You should now see:

- Two new repositories in your business (for Garage Usta: a web app and an API).
- A chat thread summarizing what was built — the screens, the data model, and what
  the AI decided along the way.
- Suggested next actions, including **Preview**.

## Next step

Your app exists, but you haven't seen it run yet. Continue the journey:
[Preview your app](/docs/get-started/preview-your-app) — or jump straight to the
[Preview Hub overview](/docs/preview-and-debug/preview-hub) if you want the full
tour of the preview system.
