Self-hosted

Download the files and host them yourself:

Initialization

JavaScript API

CuadraUIKit.init({
  baseUrl: 'https://api.cuadra.ai',
  sessionToken: 'your-session-token',
  modelId: 'your-model-id',
  mode: 'multiChat',
  modelMode: 'fixed',
  theme: 'system',
  showThemeToggle: true,
  welcomeTitle: 'Welcome!',
  welcomeSubtitle: 'How can I help you today?',
  suggestions: [
    { prompt: 'How do I get started?' },
    { prompt: 'What features do you offer?' }
  ]
});

Data Attributes (Auto-initialization)

Use data attributes for simpler setup:

<div id="cuadra-chat" 
     data-base-url="https://api.cuadra.ai"
     data-session-token="your-session-token"
     data-model-id="your-model-id"
     data-mode="multiChat"
     data-theme="system"
     style="height: 100vh; width: 100%;">
</div>

<script src="https://unpkg.com/@cuadra-ai/uikit@latest/dist/widget/cuadra-uikit.umd.js"></script>

The widget auto-initializes when data attributes are present.

Authentication Options

CuadraUIKit.init({
  baseUrl: 'https://api.cuadra.ai',
  sessionToken: 'your-session-token',
  modelId: 'your-model-id'
});

CuadraUIKit.init({

});

Embedded in Existing Page

<!-- Add to your existing page -->
<div id="chat-container" style="width: 400px; height: 600px; position: fixed; bottom: 20px; right: 20px; border-radius: 12px; overflow: hidden; box-shadow: 0 4px 24px rgba(0,0,0,0.15);">
  <div id="cuadra-chat" style="height: 100%; width: 100%;"></div>
</div>

<link rel="stylesheet" href="https://unpkg.com/@cuadra-ai/uikit@latest/dist/widget/cuadra-uikit.css">
<script src="https://unpkg.com/@cuadra-ai/uikit@latest/dist/widget/cuadra-uikit.umd.js"></script>
<script>
  CuadraUIKit.init({
    baseUrl: 'https://api.cuadra.ai',
    sessionToken: 'your-token',
    modelId: 'your-model-id',
    mode: 'singleChat'
  });
</script>

With Proxy Backend

<div id="cuadra-chat" style="height: 100vh;"></div>

<script src="https://unpkg.com/@cuadra-ai/uikit@latest/dist/widget/cuadra-uikit.umd.js"></script>
<script>
  CuadraUIKit.init({
    proxyUrl: '/api/chat',
    modelId: 'model_abc123',
    mode: 'multiChat'
  });
</script>

Styling & Customization

Container Sizing

The widget fills its container. Control size via the container:

<!-- Full page -->
<div id="cuadra-chat" style="height: 100vh; width: 100%;"></div>

<!-- Fixed size -->
<div id="cuadra-chat" style="height: 600px; width: 400px;"></div>

<!-- Responsive -->
<div id="cuadra-chat" style="height: 80vh; max-width: 800px; margin: 0 auto;"></div>

Custom Styling

Override CSS variables:

<style>
  #cuadra-chat {
    --cuadra-primary: #6366F1;
    --cuadra-background: #fafafa;
    --cuadra-border-radius: 12px;
  }
</style>

WordPress Integration

Add to your theme’s footer.php or use a custom HTML block:

<!-- In footer.php before </body> -->
<div id="cuadra-chat" style="position: fixed; bottom: 20px; right: 20px; width: 380px; height: 500px; z-index: 9999;"></div>
<link rel="stylesheet" href="https://unpkg.com/@cuadra-ai/uikit@latest/dist/widget/cuadra-uikit.css">
<script src="https://unpkg.com/@cuadra-ai/uikit@latest/dist/widget/cuadra-uikit.umd.js"></script>
<script>
  CuadraUIKit.init({
    proxyUrl: '<?php echo admin_url("admin-ajax.php"); ?>?action=cuadra_chat',
    modelId: 'your-model-id',
    mode: 'singleChat'
  });
</script>

Troubleshooting

Check the container exists: document.getElementById('cuadra-chat')
Ensure CSS is loaded before the script
Check browser console for errors
Verify container has explicit height

Authentication Errors

Check session token is valid
Verify API key has correct permissions
Use browser Network tab to inspect requests

Styling Issues

Ensure CSS file is loaded
Check for CSS conflicts with your site
Use browser DevTools to inspect elements
