AI Chatbot Features

T3AC focuses on chatbot-related AI workflows built on top of the shared T3AF setup. Use these features when you want to control how the chatbot answers questions, how data is trained, and how the chatbot is shown on your site or external websites. Key T3AC capabilities include:
  • Chatbot configuration and behavior control
  • Training and data-source-based answer generation
  • Dashboard, logs, and analytics for chatbot activity
  • External embed support for approved domains
For shared model routing and central AI behavior, see T3AF AI Features.

    • Enter the Page IDs where the chatbot should be visible (e.g., 10, 22, 35).
  • Hide Chatbot on Specific Pages
    • Enter the Page IDs where the chatbot should be hidden, even if it is enabled globally (e.g., 45, 60, 72).
  • Internal CSS Configuration

    • Use your own styles to customize the chatbot appearance.
Make sure your CSS files are available inside the public directory, and the path should start with fileadmin/.

​

  1. Go to the T3AC module.
  2. Navigate to Chatbot > External Embed.
Available options:
  • Custom CSS Use your own styles to customize the chatbot appearance.

  • Allow Any Domain Enable this option to permit embedding on any domain without restrictions.
