Widget Language

Set the language for all UI elements in the widget (buttons, placeholders, system messages). English (en) is the default. You can choose any of these 14 codes: This is independent of the chatbot’s response language — the AI responds based on the system prompt and the language of the user’s question.

​
Live Preview

The right side of the Appearance settings shows a live conversation preview that updates as you change settings. It renders:
  • The header with your chosen style
  • A sample conversation with message bubbles
  • The input field with your placeholder text
  • The chat bubble with your primary color
Test both light and dark modes in the preview. Some color combinations look great in light mode but have poor contrast in dark mode.
