Build your first app

Describe it, run it, watch it verify itself.

Building with quez is a conversation. You say what you want, quez builds it, and you keep chatting to refine it — just like working with a developer.

1. Describe what you want

In the Agent box on the left, type a plain-English description. Be specific about the important parts:

• "Build a todo app with dark mode and the ability to mark tasks done."
• "A landing page for my bakery with a hero, menu, and contact form."
• "A simple expense tracker that saves to a database."

2. Watch it build

quez plans the work, then writes the files — you'll see them appear in the Files panel on the right, and the steps stream in the Agent panel.

3. Run & preview

Press ▶ Run to start your app. It appears live in the Preview tab — click around and try it, just like a real website.

4. It checks its own work

This is what makes quez different: after building, it tests the app itself — you'll see green ✓ checks confirming the page loads, renders, and has no errors. If something's broken, quez catches and fixes it.

5. Keep refining

Just keep chatting: "make the header purple", "add a delete button", "put the total at the top." quez remembers your project, so you can pick up where you left off anytime.

Tips for great results

• Start simple, then add. Get a basic version working, then layer on features.
• One change at a time when refining — it's easier to see what happened.
• Say the "why" ("so customers can book a table") — it helps quez make better choices.
• Prefer to tinker? There's a full code editor built in — jump into any file anytime.
