SiteAnswerAI adds an AI assistant to your WordPress site that answers visitor questions using your own website content. When a visitor asks about your services, products, policies, or anything else covered on your site, the assistant responds with relevant answers drawn from your pages.
This is useful for handling support questions, pre-sales inquiries, product lookups, and general site navigation — without requiring you to be online or manage a live chat queue.
Who is this for?
<ul>
<li>Business owners who want to reduce repetitive support questions</li>
<li>WooCommerce store owners who want visitors to get quick answers about products, pricing, and availability</li>
<li>Service providers who want an always-available assistant on their website</li>
<li>Anyone who wants to help visitors find information on their site faster</li>
</ul>
What you get:
<ul>
<li>An AI assistant that reads and learns from your website content</li>
<li>Automatic answers to visitor questions based on your pages, posts, and products</li>
<li>A clean chat widget that appears on your site frontend</li>
<li>WooCommerce awareness — the assistant can reference product names, prices, stock status, and descriptions</li>
<li>Full branding control — match your site colors, position the widget where you want it</li>
<li>A hosted dashboard for conversation history, prompt customization, and AI training</li>
<li>Lightweight loading — the widget script loads asynchronously and does not block page rendering</li>
</ul>
How setup works:
<ol>
<li>Install and activate the plugin</li>
<li>Visit any admin page — the plugin automatically provisions your AI assistant by sending your site URL, site name, and admin email to the SiteAnswerAI service</li>
<li>SiteAnswerAI begins crawling your website to build the assistant’s knowledge base</li>
<li>The chat widget appears on your site frontend once provisioning is complete</li>
<li>Optionally, check the email sent to your admin address to set a dashboard password for advanced settings</li>
</ol>
No separate registration or signup form is required. The plugin handles provisioning automatically on first use. If you already have a SiteAnswerAI account associated with your admin email, the plugin connects to your existing account instead.
WooCommerce integration:
If WooCommerce is active, you can connect your product catalog from the plugin settings page. The plugin creates a read-only WooCommerce REST API key and transmits it to SiteAnswerAI over HTTPS. This allows the assistant to answer product questions using real-time data — including prices, stock status, variants, and descriptions. The API key is read-only and cannot modify your store.
Performance:
The widget script is enqueued with an async loading strategy and renders in the footer. It does not block your page content from loading and works alongside caching plugins and page builders without conflict.
Customization:
From the WordPress settings page, you can control:
<ul>
<li>Widget position (bottom-right or bottom-left)</li>
<li>Primary color</li>
<li>Header and footer colors (or leave blank to use your dashboard defaults)</li>
<li>Enable/disable toggle</li>
</ul>
For deeper customization — including prompt tuning, personality settings, and conversation review — use the SiteAnswerAI dashboard linked from the plugin settings page.
Developer-friendly:
<ul>
<li><code>siteanswerai_show_widget</code> filter to control widget visibility per page</li>
<li><code>siteanswerai_app_url</code> filter and <code>SITEANSWERAI_APP_URL</code> constant for self-hosted setups</li>
<li>Helper functions: <code>siteanswerai_is_enabled()</code>, <code>siteanswerai_get_bot_id()</code>, <code>siteanswerai_is_configured()</code>, and more</li>
</ul>
Requirements:
<ul>
<li>WordPress 5.0 or higher</li>
<li>PHP 7.4 or higher</li>
</ul>
<h3>Third-Party Services</h3>
This plugin connects to external services to provide AI-powered chat functionality. Below is a clear description of each service, what data is sent, and when.
<h4>SiteAnswerAI</h4>
The primary service that powers the AI assistant. Handles chatbot provisioning, content indexing, conversation processing, and widget delivery.
<ul>
<li>Homepage: <a href="https://siteanswerai.com" rel="nofollow ugc">https://siteanswerai.com</a></li>
<li>API endpoint: <a href="https://siteanswerai.com" rel="nofollow ugc">https://siteanswerai.com</a></li>

<li>Privacy Policy: <a href="https://siteanswerai.com/privacy" rel="nofollow ugc">https://siteanswerai.com/privacy</a></li>
</ul>
When data is sent to SiteAnswerAI:
<ol>
<li>On the first WordPress admin page load after plugin activation, the plugin sends your site URL, site name, and WordPress admin email to provision your AI assistant. This also occurs on first settings save if auto-provisioning has not yet completed.</li>
<li>When the chat widget is enabled and a visitor loads any frontend page, the visitor’s browser requests the widget script and configuration from SiteAnswerAI servers.</li>
<li>When a visitor sends a chat message, their message text and the current page URL are sent to SiteAnswerAI for AI-powered response generation.</li>
<li>If WooCommerce integration is connected, a read-only WooCommerce REST API key is transmitted once over HTTPS so SiteAnswerAI can read your product catalog.</li>
</ol>
What data is sent:
<ul>
<li>WordPress admin email, site URL, and site name (during provisioning)</li>
<li>Bot ID and widget display settings</li>
<li>Visitor chat messages and page URLs (during conversations)</li>
<li>Read-only WooCommerce API credentials (only when WooCommerce integration is explicitly connected by a site administrator)</li>
</ul>
<h4>OpenAI Realtime API (Optional)</h4>
When voice features are enabled through the SiteAnswerAI dashboard, the widget may use the OpenAI Realtime API for voice-based interactions. Audio is recorded in the visitor’s browser and sent directly to OpenAI. No audio data is stored on the WordPress server.

Important Notice for Users Updating to Version 1.6.6+
The latest update improves the plugin’s file structure for better performance. As a result, the default paths for some images (like the chatbot icon and avatars) have changed.
If you notice that the chatbot button or avatars are not appearing after the update, it is almost certainly due to your browser or website’s cache.
Solution: Please perform a “hard refresh” in your browser (Ctrl+F5 on Windows/Linux, Cmd+Shift+R on Mac). If you use a caching plugin (like WP Rocket, LiteSpeed, WP Fastest Cache etc.), please purge all caches from your plugin’s settings. This will solve the issue.

<h3>Configuration – Setting up your AI Chatbot</h3>
<ol>
<li>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!</li>
<li>Enter your OpenRouter API Key in the “Settings” tab.</li>
<li>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.</li>
<li>Provide context about your website in the “Information for responses” field.</li>
<li>Customize the chatbot’s appearance in the “Style” and “Images” tabs.</li>
<li>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.</li>
</ol>
<h3>Message and IP Saving</h3>
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:
<ul>
<li>Simplified Management: All chatbot-related data is contained in a single location, making it easier to manage and maintain.</li>
<li>Reduced Impact: Storing data separately minimizes the impact on your website’s core database performance.</li>
</ul>
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.
