Getting Started

Quick Start

From zero to a working app in under 5 minutes.

  1. 1

    Create an account

    Go to /auth and sign in with Google. No email or password needed.

  2. 2

    Add an AI key

    Go to Settings → API Keys and paste your Groq API key (free, fastest) or your OpenRouter key. Keys are encrypted with AES-256 before being stored — we never see them in plaintext.

  3. 3

    Create your first app

    Go to the Dashboard and click "New App". Give it a name, then click Create.

  4. 4

    Describe what you want

    Type a description in the chat panel. Be specific: include field names, features, and data you want to track. Hit Enter or click Send.

    "Build a habit tracker. Track daily habits with a name, frequency (daily/weekly), and a streak counter. Show a calendar heat-map."
  5. 5

    Watch it build

    The AI streams code directly into the preview panel. You'll see your app come to life in real time. The code tab updates simultaneously.

  6. 6

    Iterate

    Not quite right? Just type a follow-up. "Add a dark/light mode toggle." "Change the accent colour to teal." "Add chart.js bar chart for weekly completions." Each message updates the existing app.

  7. 7

    Deploy or Download

    Hit Deploy for a shareable URL on your domain, or Download for a standalone HTML zip file that works completely offline.
