External services

This plugin connects to third-party AI APIs to provide chatbot responses. The site administrator configures ONE of the following providers in the settings; only the selected provider receives data (not all three).

1. OpenAI (ChatGPT)

What it is and what it is used for: OpenAI’s Chat Completions API powers the chatbot when “OpenAI” is selected. It processes visitor messages and returns AI-generated replies that guide users to relevant content on your site.
What data is sent and when: Each time a visitor sends a chat message, the plugin sends to OpenAI: the visitor’s message, the conversation history for that session (if any), a system prompt with instructions, and—when the AI performs a site search—the titles, URLs, and excerpts of matching WordPress posts and pages. Data is sent only when the visitor submits a message and OpenAI is the configured provider.

What data is sent and when: Each time a visitor sends a chat message, the plugin sends to Google: the visitor’s message, the conversation history for that session (if any), a system prompt with instructions, and—when the AI performs a site search—the titles, URLs, and excerpts of matching WordPress posts and pages.

General notes

API keys are stored encrypted on your WordPress site and are only accessible to logged-in administrators. They are never sent to visitors or exposed in front-end code.
The plugin applies rate limits (10 chat requests per minute per IP) to protect against abuse. Separately, a site-wide daily limit on content searches applies to all visitors together (configurable in settings; 0 = unlimited).
Site owners should disclose this data flow in their site’s privacy policy and obtain any consent required in their jurisdiction.
