Configuration – Setting up your AI Chatbot

  1. Get a Free API Key from OpenRouter.ai (Yes, it’s free!). OpenRouter offers access to over 400 models, including ChatGPT, Claude, DeepSeek, Gemini, and many others, all at competitive prices!
  2. Enter your OpenRouter API Key in the “Settings” tab.
  3. Choose an AI Model. Free models have the suffix “:free” at the end of their name. Note that all models are accessed THROUGH OpenRouter, regardless of the original provider.
  4. Provide context about your website in the “Information for responses” field.
  5. Customize the chatbot’s appearance in the “Style” and “Images” tabs.
  6. Click “Save settings”. Remember to refresh your website (Ctrl+F5 or Cmd+Shift+R) after saving, otherwise the changes may not be displayed correctly due to caching.

Message and IP Saving

You can enable or disable the saving of chat messages and user IP addresses in the “Messages” tab of the settings page. Message saving is disabled by default for privacy reasons. If enabled, all chat messages and IP addresses will be stored securely within the plugin’s dedicated database.

Using a dedicated database offers several advantages:

  • Simplified Management: All chatbot-related data is contained in a single location, making it easier to manage and maintain.
  • Reduced Impact: Storing data separately minimizes the impact on your website’s core database performance.

Important: If you choose to enable message and IP saving, you MUST update your website’s privacy policy to reflect this data collection practice and inform your users accordingly. You are responsible for complying with all applicable privacy laws.

Great plugin! Super easy to set up, and I’m genuinely impressed that I can use Google Gemma 3 (27B) for free with no limits. Exactly what I was looking for, an advanced AI chatbot with zero cost.
