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>

<h3>Lead Management Dashboard — Turn Chat Traffic Into a Real Lead List</h3>
Every email and name your chatbot captures now lands in one clean, sortable dashboard — so you can finally see your leads as a list instead of hunting through individual transcripts.
What You Get:
<ul>
<li>One Row Per Lead — emails captured across multiple sessions are automatically deduplicated, so each lead appears once with a conversation count and a “last seen” timestamp</li>
<li>Top Pages Capturing Leads — instantly see which pages on your site are driving the most lead captures; click any page to filter the list to leads from that page only</li>
<li>Powerful Filtering — search by email or name, filter by date range (24h / 7d / 30d / 90d / all-time), or filter by status (leads with a conversation vs. orphan leads who submitted the form but never chatted)</li>
<li>Orphan Lead Tracking — visitors who drop their email in the pre-chat form but never send a message are surfaced separately so you never lose a captured contact</li>
<li>One-Click View Conversation — jump from any lead straight into their latest full conversation in the transcripts viewer</li>
<li>Bulk Delete + CSV Export — select multiple leads to delete or export in one action; CSV export supports email-only or email + name + conversation count + last-seen + top page</li>
<li>Clean, Responsive, Native — works beautifully on desktop, tablet, and phone with the same polished dashboard feel as the rest of MxChat</li>
<li>Zero Setup, Zero Migration — uses your existing chat data, no new database tables, no configuration — turn on lead capture and the dashboard just works</li>
</ul>
Perfect for sales teams managing inbound leads, agencies reporting to clients, and anyone who wants to see the actual ROI of their chatbot at a glance without digging through individual conversations.
<h3>AI Content Generator — Create Blog Posts & Landing Pages with AI</h3>
MxChat includes a built-in AI Content Generator that lets you create full blog posts and landing pages directly from your WordPress dashboard — no external tools or copy-pasting required.
How It Works:
<ol>
<li>Describe Your Content — Enter a topic, title, or detailed prompt and choose between a blog post or landing page layout</li>
<li>AI Generates Everything — The AI produces fully styled HTML with responsive CSS, ready-to-publish content, and optional AI-generated images using OpenAI GPT Image, Gemini, or Grok</li>
<li>Real-Time Preview — See your content exactly as it will appear on your site with a live scaled preview, including desktop and mobile viewport switching</li>
<li>Edit with AI Chat — Use the built-in AI chat panel to request changes like “make the heading bigger” or “change the background to blue” — the AI updates your content in real time</li>
<li>Publish Instantly — Content is saved as a native WordPress post or page with clean HTML, SEO metadata, and responsive design that works with any theme</li>
