Trill AI Chat adds an intelligent shopping assistant to your WooCommerce store — completely free. Your customers can ask questions about products, get personalised recommendations, and add items to their cart, all through a natural chat conversation. No API key required, no complex setup, no coding.
Meet Robin, your AI-powered shop assistant. Robin understands your product catalogue in real time, searches by name, category, price, and availability, and presents results as interactive product cards with one-click add-to-cart buttons.
<h4>Why Trill AI Chat?</h4>
Unlike generic chatbot plugins that require you to bring your own API key and configure prompts manually, Trill AI Chat works out of the box. Install, activate, and your store has a fully functional AI assistant in under two minutes. The AI service is managed for you — no OpenAI account needed, no token costs to worry about, no prompt engineering required.
<h4>Key Features</h4>
<ul>
<li>Instant AI chat widget — A clean, modern chat bubble appears on your storefront. Fully responsive on mobile and desktop. Customers can start chatting immediately.</li>
<li>Real-time product search — Robin searches your WooCommerce products by name, description, category, and tags. Results appear as rich product cards with images, prices, and stock status.</li>
<li>Natural language understanding — Customers can ask questions the way they naturally would: “do you have any red dresses under £50?”, “what’s on sale?”, “show me accessories for hiking”. Over 50 common shopping phrases are recognised automatically.</li>
<li>Smart de-pluralisation — Searching for “t-shirts” correctly matches “T-Shirt”, “accessories” matches “Accessory”. English plural forms are handled intelligently.</li>
<li>One-click add to cart — Product cards include an “Add to Cart” button that works via AJAX, so customers never leave the conversation.</li>
<li>Quick reply buttons — Contextual suggestions like “Browse products”, “What’s on sale?”, and “Shipping info” help guide the conversation naturally.</li>
<li>Non-product query handling — Questions about shipping, returns, payment methods, and order status are recognised and answered without triggering unnecessary product searches.</li>
<li>Customisable appearance — Choose your brand colour, widget position (bottom-left or bottom-right), and set a custom welcome message. The widget adapts to your store’s look and feel.</li>
<li>No API key required — The AI is powered by the Trill AI managed service. No need to create accounts with OpenAI, Anthropic, or any other provider. Just activate and go.</li>
<li>Lightweight and fast — No external JavaScript libraries, no Composer dependencies, no bloat. Built with vanilla JavaScript and native WordPress APIs for maximum performance.</li>
<li>WooCommerce HPOS compatible — Fully compatible with WooCommerce High-Performance Order Storage.</li>
<li>GDPR-friendly — No personal data is collected beyond what is strictly needed to process each chat message. Messages are not used for AI training. Full details in our Privacy Policy.</li>
<li>Shortcode support — Use <code>[trill_chat]</code> to embed a chat trigger button on any page or post. Supports <code>style</code>, <code>title</code>, and <code>button_text</code> attributes.</li>
<li>Developer-friendly — Clean PSR-4 architecture, WordPress coding standards, filter hooks for customisation (<code>trcl_localize_script_data</code>), and debug logging via WP_DEBUG.</li>
</ul>
<h4>How It Works</h4>
<ol>
<li>Install and activate — Upload from the WordPress plugin directory or search “Trill AI Chat” in Plugins > Add New.</li>
<li>Automatic product indexing — Robin scans your WooCommerce catalogue automatically. No manual configuration needed.</li>
<li>Customers start chatting — The chat widget appears on your storefront. Visitors ask questions, Robin searches your products in real time and responds with relevant results.</li>
<li>You track usage — The admin dashboard shows your monthly conversation count and product index status.</li>
</ol>
<h4>Built for WooCommerce Store Owners</h4>
Trill AI Chat is purpose-built for e-commerce. Unlike general-purpose chatbot plugins that try to do everything, Robin focuses on what matters most for online stores: helping shoppers find and buy products. Every feature — from product card rendering to cart integration — is designed specifically for WooCommerce.

<h3>External Services</h3>
This plugin relies on the Trill AI API (<code>https://api.trillai.io</code>) as its 
sole AI processing back-end. The service is required for the plugin to function.
What data is sent and when:
<ul>
<li>When a store visitor sends a chat message, the message text and relevant 
WooCommerce product context (names, prices, descriptions) are transmitted to 
the Trill AI API over HTTPS for AI processing.</li>
<li>The API also enforces per-site usage limits server-side (no local trialware).</li>
</ul>

<li>Privacy Policy: https://trillai.io/privacy/</li>
</ul>
No personal visitor data is collected or stored by the external service beyond 
what is strictly necessary to process the individual chat message. Messages are 
not used for training AI models.
