NVT AI Chatbot connects your WordPress site to the NVT SaaS platform to deliver an AI-first support experience for WordPress and WooCommerce stores.
The plugin focuses on three core jobs:
<ul>
<li>Answer with your own knowledge base: Use Retrieval-Augmented Generation (RAG) so the chatbot answers from your website content and uploaded documents.</li>
<li>Escalate to a human when needed: When AI is not enough, visitors can switch to Live Chat and your team can continue the conversation from the built-in Inbox.</li>
<li>Support WooCommerce sales and support flows: Help customers discover products, manage cart actions, move toward checkout, and ask about recent orders.</li>
</ul>
Main features:
<ul>
<li>AI Chatbot (RAG): Grounded answers based on your website content and uploaded files.</li>
<li>Website Crawl + File Ingestion: Crawl your site manually or on a schedule, or upload files such as PDF, DOCX, TXT, MD, HTML, CSV, XLS, XLSX, and PPTX.</li>
<li>Live Agent Handoff: Switch between AI and Live Chat using schedule rules, manual override, or user request.</li>
<li>WooCommerce Product Support: Search products, recommend items, and show product cards inside chat.</li>
<li>WooCommerce Cart Actions: Add to cart from chat, refresh cart summary, update quantities, or remove items.</li>
<li>WooCommerce Checkout Assist: Detect checkout requirements, collect required fields, show payment methods, and create an order from chat when your store supports it.</li>
<li>Order Lookup: Surface recent order information for logged-in or identified customers.</li>
<li>WooCommerce-Aware Agent Inbox: Support agents can see useful context such as contact info, last seen page, recently viewed pages, cart snapshot, and recent orders.</li>
<li>Personalized User Context: Logged-in WordPress/WooCommerce users can be recognized automatically for more relevant support.</li>
<li>Live Chat Uploads: Visitors can send images, documents, and voice messages during live chat with staff.</li>
<li>Widget Customization: Choose theme mode, colors, avatars, widget position, welcome message, sound, and custom button image.</li>
<li>Admin Workspace: Includes Dashboard, Account, Settings, Data Sources, Inbox, Playground, and Feedback tabs.</li>
<li>CSV Export: Export leads and full conversation history from the Inbox.</li>
<li>Admin Notifications: Unread chat badge and real-time admin notifications help your team respond faster.</li>
</ul>
This makes the plugin suitable for:
<ul>
<li>business websites that want a knowledge-based AI assistant,</li>
<li>WooCommerce stores that need AI sales/support automation,</li>
<li>teams that want AI first, with a real human ready to step in when necessary.</li>
</ul>

Smart Support Chat Widget turns your WordPress site into a SmartSupport-powered experience by keeping RAG (Retrieval-Augmented Generation) collections synced and feeding your SmartSupport AI agent the freshest content. Deploy the SmartSupport chat widget on any page and it will respond to visitors using the local page context plus the RAG collections you curate—all from the familiar WordPress admin.
Key capabilities
<ul>
<li>AI chatbot ready out of the box: Drop in the SmartSupport chat widget and your AI agent answers questions using the current page content and any RAG collections you mapped in WordPress.</li>
<li>Choose your RAG sources: Create SmartSupport RAG collections for posts, pages, or custom post types and include default WordPress fields, custom meta, ACPT fields, and even the canonical post URL.</li>
<li>Automatic or manual indexing: Let Smart Support Chat Widget push updates every time you hit “Save,” or switch to manual mode for full editorial control.</li>
<li>Bulk tools built in: Run a batch sync (up to 50 posts at once) whenever you need to catch SmartSupport up with your latest work.</li>
<li>One-click commands: From the post list screen you can index, re-index, or clear a record without opening a single editor screen.</li>
<li>Safe cleanup: When you trash or delete a post, Smart Support Chat Widget removes the associated SmartSupport record so your external knowledge base stays tidy.</li>
<li>Frontend ready: On single posts, Smart Support Chat Widget outputs hidden inputs containing the SmartSupport collection name and record ID—handy for custom chat widgets or headless front-ends.</li>
</ul>
