Overview: Theming & OpenAI Integration (Free + Pro)

1. What “Theming & OpenAI” Covers #

Section 5 of your documentation explains that this feature group is responsible for:

• All visual theming of the chatbot:
  • Light and dark color palettes.
  • Bubble, text, chip, and input colors.
  • Button visibility and sizes.
• All OpenAI integration:
  • API key.
  • Model (fixed gpt-4o-mini in Free; selectable in Pro).
  • System prompt.
  • Temperature.
  • Optional site-search grounding.

It complements the core chatbot feature described in section 4, rather than replacing it.

2. Where to Configure Theming & OpenAI #

You configure these settings under:

• WordPress Admin → Davix AI Engine → Chatbot

In that screen, you’ll use these main tabs (names may vary slightly, but content is described in the docs):

• General / Style – branding, base colors.
• Buttons – button visibility and icon sizes.
• Login Required – gate styling when login is required.
• OpenAI Integration – API key, model, system prompt, temperature, site search.
• Advanced / Custom CSS – extra CSS (mentioned in docs as “Advanced / Custom CSS”).

Each later article in this category will focus on one of these areas.
