IllumiChat

IllumiChat is a customer-support chat widget powered by an AI agent that answers product questions, looks up orders, updates customer info, and recovers carts on your WooCommerce store.
This plugin:
<ul>
<li>Installs the chat widget on your storefront with one click (no code edits).</li>
<li>Connects your store to your IllumiChat assistant via the WooCommerce REST API.</li>
<li>Supports the wc-auth/v1/authorize OAuth-style consent flow — no manual key generation required.</li>
<li>Honors GDPR cookie consent (CookieYes / Complianz / WPConsent) before loading.</li>
</ul>
You will need an IllumiChat account and an assistant ID. Sign up at https://illumichat.com.
<h3>External services</h3>
This plugin connects to IllumiChat, a third-party Software-as-a-Service operated by IllumiChat (https://illumichat.com), to deliver chat responses and synchronize WooCommerce data. Use of this plugin requires registering an IllumiChat account; activating and configuring the plugin constitutes opt-in to the data flows below.
Service: IllumiChat (https://app.illumichat.com) 
Privacy policy: https://illumichat.com/legal/privacy-policy 
Terms of service: Contact support@illumichat.com
What data is sent, when, and why:
<ul>
<li>On connect (when the site admin clicks “Connect IllumiChat” in WooCommerce → IllumiChat): the configured Assistant ID, the store URL, and — via the WooCommerce wc-auth/v1/authorize consent flow approved by the admin — WooCommerce REST API Consumer Key and Consumer Secret are transmitted to https://app.illumichat.com so that IllumiChat can read products, orders, and customers from the store on the admin’s behalf.</li>
<li>On every storefront page view (when the widget is enabled and visitor consent is satisfied): the visitor’s browser fetches the chat widget loader from https://app.illumichat.com/api/woocommerce/widget-loader/. The request includes only standard browser headers; no personal data is appended by the plugin.</li>
<li>During a chat session (when a storefront visitor types a message into the widget): the message text and minimal session/context data are sent from the visitor’s browser to https://app.illumichat.com for AI processing and reply.</li>
<li>Webhook callbacks (asynchronous, server-to-server): when product/order/customer data changes in WooCommerce, your WordPress site posts the WooCommerce webhook payload to https://app.illumichat.com so IllumiChat’s grounding data stays in sync.</li>
</ul>
All transport is over HTTPS. The admin can revoke the connection at any time from WooCommerce → IllumiChat (which clears the stored Assistant ID) or from WooCommerce → Settings → Advanced → REST API (which revokes the Consumer Key/Secret).

<h4>Core Features</h4>
Your AI chatbot includes everything you need for customer support, lead generation, and engagement:
✅ Conversational Forms 
Your AI doesn’t just answer questions—it can run conversational forms when visitor intent matches your configuration: the chatbot collects standard fields through dialogue. You can also use widget forms—the type is chosen when you set up the form (conversational vs widget). Submissions are stored locally, and each new entry can be delivered by email or Slack.
✅ Quick 3-Step AI Chatbot Setup 
Guided wizard launches after activation. Connect your AI provider, configure personality, add knowledge sources, and customize appearance—live in under 5 minutes.
✅ Advanced AI Chatbot RAG Technology 
Train on unlimited WordPress content using Retrieval-Augmented Generation. Supports pages, posts, custom post types, PDFs, text files, rich text input, Q&A entries, and webpage content fetched from URLs. Intelligent intent recognition retrieves the most relevant knowledge for accurate responses. Auto-sync keeps WordPress knowledge sources (pages, posts, custom post types) automatically up to date—no manual re-training needed when content changes. Knowledge Filtering lets you accurately filter and view which sources are available in your knowledge base. AI Agent can also render images from learned sources (Beta) for richer, more visual responses.
✅ Transcripts 
View all chats, see which knowledge sources were used per reply, add missing Q&A entries, and review user context (guest/logged-in status and IP addresses).
✅ Cost-Optimized AI Usage 
Smart token management minimizes API charges. Intelligent request optimization ensures you pay only for what you need. Configure rate limits to control expenses.
✅ Streaming AI Responses 
Real-time word-by-word AI replies for faster, more natural conversations. Especially useful when short answers setting is disabled – long responses are printed naturally and quickly instead of making users wait for the full response to be ready.
✅ Customizable Chat Experience 
Unlimited widgets including Message Starters, Message Prompts, Chat History, Links, Lead Generation, and custom announcements. The Lead Generation widget collects user name and email before allowing conversation to start—so you know who is chatting and can follow up or add them to your leads list. Fully customizable greetings with emoji support. Simplified single-step widget publishing makes adding widgets effortless.
✅ Flexible Vector Storage 
Choose local WordPress database (free, unlimited) or Pinecone for enterprise-scale knowledge bases. Vector embeddings enable fast, contextually relevant retrieval.
✅ Complete Customization 
Customize colors, chatbot icon, AI avatar, chat box size, themes (light/dark/system), positioning, emojis, and greeting messages. Adapts seamlessly to all devices.
✅ Multi-Language Support 
Conversations in multiple languages with RTL compatibility. The AI chatbot responds in your visitors’ language.
✅ GDPR Compliant 
All conversation data stored locally on your WordPress site. You control data retention, export, and deletion policies.
