NVT AI Chatbot – RAG & Live Chat

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:

• Answer with your own knowledge base: Use Retrieval-Augmented Generation (RAG) so the chatbot answers from your website content and uploaded documents.
• 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.
• Support WooCommerce sales and support flows: Help customers discover products, manage cart actions, move toward checkout, and ask about recent orders.

Main features:

• AI Chatbot (RAG): Grounded answers based on your website content and uploaded files.
• 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.
• Live Agent Handoff: Switch between AI and Live Chat using schedule rules, manual override, or user request.
• WooCommerce Product Support: Search products, recommend items, and show product cards inside chat.
• WooCommerce Cart Actions: Add to cart from chat, refresh cart summary, update quantities, or remove items.
• WooCommerce Checkout Assist: Detect checkout requirements, collect required fields, show payment methods, and create an order from chat when your store supports it.
• Order Lookup: Surface recent order information for logged-in or identified customers.
• 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.
• Personalized User Context: Logged-in WordPress/WooCommerce users can be recognized automatically for more relevant support.
• Live Chat Uploads: Visitors can send images, documents, and voice messages during live chat with staff.
• Widget Customization: Choose theme mode, colors, avatars, widget position, welcome message, sound, and custom button image.
• Admin Workspace: Includes Dashboard, Account, Settings, Data Sources, Inbox, Playground, and Feedback tabs.
• CSV Export: Export leads and full conversation history from the Inbox.
• Admin Notifications: Unread chat badge and real-time admin notifications help your team respond faster.

This makes the plugin suitable for:

• business websites that want a knowledge-based AI assistant,
• WooCommerce stores that need AI sales/support automation,
• teams that want AI first, with a real human ready to step in when necessary.
