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>
When data is sent to SiteAnswerAI:

<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.

<h3>⚙️ Frequently Asked Questions</h3>
<h4>Do I need an API key or account to use this plugin?</h4>
You need to register at WebChatAgent.com to create a chatbot and get a Chatbot ID. You then enter this ID in the plugin settings to connect your WordPress site to your chatbot. API keys and model settings are managed in your WebChatAgent account.
<h4>Is this plugin completely free?</h4>
You can start with a free plan on WebChatAgent.com. There are paid plans available if you need higher limits, more pages, more traffic or advanced features like higher message quotas, team features and additional integrations.
<h4>Can I customize the appearance of the chat widget?</h4>
Yes. You customize the color scheme, avatar, fonts, welcome message, widget position, behavior and persona directly in the WebChatAgent dashboard. The WordPress plugin shows a live preview and uses your current configuration.
<h4>Is WebChatAgent GDPR (DSGVO) compliant?</h4>
Yes. WebChatAgent operates in accordance with the GDPR. IP addresses are stored in anonymized form for abuse prevention, chat conversations are kept only for a limited time, and old conversations and personal data are cleaned up automatically after a configurable retention period. See the Privacy Policy section below for details.
<h4>Can I embed the chat inside a page instead of the floating button?</h4>
Yes. Use the <code>[webchatagent_inline]</code> shortcode (Classic Editor, page builders, text widgets) or the WebChatAgent Inline Chat Gutenberg block to place the chat directly inside your content — for example on a product page, contact page or news article. Both use the Chatbot ID from the plugin settings; you can override it per embed with <code>chatbot-id="..."</code> (or via the block sidebar). The inline embed works independently of the Enable Chatbot toggle, which only controls the floating widget, and the widget script loads only on pages that use it.
<h4>Is the chat widget mobile-friendly?</h4>
Yes, the chat widget is fully responsive and works well on all devices, including mobile phones and tablets.
<h4>Does WebChatAgent support live chat and human takeover?</h4>
Yes. WebChatAgent offers a hybrid model: AI answers most questions automatically, and your team can take over any chat at any time via the Agent Inbox. You can reply as a human and then hand control back to the bot if you like.
<h4>Does the plugin support WhatsApp Business?</h4>
Yes. You can connect your WhatsApp Business number in the WebChatAgent dashboard. Your AI chatbot can then reply to WhatsApp messages, and you can manage those conversations alongside website chats.
<h4>How does the AI chatbot understand my website content?</h4>
WebChatAgent uses RAG (Retrieval-Augmented Generation) to index and understand your website content and documents. When visitors ask questions, the AI combines this indexed content with a large language model (e.g. ChatGPT or Gemini) to provide accurate, context-aware answers.
<h4>Which AI models are supported?</h4>
The chatbot supports multiple large language models including OpenAI ChatGPT, Google Gemini (incl. Gemini 3.5 Flash), xAI Grok, and Mistral AI. You can choose which model to use in your WebChatAgent settings. Speed and quality indicators help you pick the right model. Additionally, you can connect custom MCP (Model Context Protocol) servers for self-hosted or specialized AI models.
<h4>Does the chatbot support multiple languages?</h4>
Yes, the chatbot automatically detects and responds in the user’s language, making it ideal for multilingual websites. Human replies in the inbox can also be auto-translated.
<h4>Is the chat widget accessible for people with disabilities?</h4>
Yes, the chat widget is designed to meet WCAG 2.2 AA accessibility standards, ensuring it’s usable for all visitors, including those using assistive technologies.
<h4>Can the chatbot perform actions beyond just answering questions?</h4>
Yes. With Tool Integrations, your chatbot can connect to external services and systems to perform actions such as submitting forms, booking appointments, updating records or querying databases. You configure these tools in your WebChatAgent dashboard.
<h4>What is the API Connector and how does it work?</h4>
The API Connector lets your chatbot answer questions that require live data from your WooCommerce shop or other business systems. Instead of just answering general questions, your chatbot can look up real information for each customer.
WooCommerce examples:
<ul>
<li>“Where is my order #12345?” – The chatbot checks your WooCommerce shop and tells the customer the current order status</li>
<li>“Is the blue T-shirt in size M available?” – Looks up product stock and availability in WooCommerce</li>
<li>“Show me my recent orders” – Displays the customer’s order history from your shop</li>
</ul>
Other systems:
<ul>
<li>Support tickets – Show ticket status from helpdesk systems</li>
<li>Account info – Look up balances, memberships or custom data from any system</li>
</ul>
How to set it up:
<ol>
<li>Select the WooCommerce template (or another template for your system)</li>
<li>The chatbot asks customers to verify their identity (e.g. their order email)</li>
<li>Once verified, the chatbot can look up their orders, products and personal data</li>
</ol>
No programming knowledge required — the WooCommerce connector works out of the box.
<h4>What analytics and management tools are included?</h4>
From your WebChatAgent account, you can access:
<ol>
<li>Lead Management – Collect, categorize and follow up with leads generated through your chatbot </li>
<li>Feedback Management – Review and analyze user feedback to improve your chatbot and service </li>
<li>Questions Management – View all questions asked to your chatbot, identify common topics and improve your knowledge base </li>
<li>Analytics Dashboard – Track conversations, leads, bookings, human handovers and unanswered questions</li>
</ol>
<h4>How does the spam protection work?</h4>
Built-in spam and abuse protection monitor usage patterns and prevent abusive or excessive requests. This helps protect your account from unexpected usage spikes and keeps your costs predictable on higher tiers.
