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>

</ul>
Main features:
<ul>

<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>

NVT AI Chatbot – RAG & Live Chat

AI-first RAG chatbot with live agent handoff and deep WooCommerce support for products, cart, checkout, and orders.

rapls

Add an AI chatbot to WordPress that answers visitors from your own content — not generic web answers. When someone asks a question, Rapls AI Chatbot searches your posts, pages, and knowledge base first, then replies in natural language, in the visitor’s own language. It turns the content you already have into a 24/7 assistant for support, pre-sales, and FAQs.
You can be live in about five minutes, for free, with no credit card. On first setup a guided “Start for free” panel hands you a free key from OpenRouter or the Google Gemini free tier, tests it, auto-selects a working model, and switches the chatbot on — no AI or API experience needed. There is no monthly SaaS fee and no per-message markup: it runs on your own API key, and your conversations stay on your own server.
Built for site owners, agencies, and developers who want control over the model, the data, and the cost. Connect OpenAI, Anthropic Claude, Google Gemini, or OpenRouter, and switch anytime.
<h4>Why site owners pick Rapls</h4>
<ul>
<li>Free to try, fast to launch. Guided onboarding gets you from install to a working chatbot in minutes, with a no-credit-card OpenRouter or Gemini key.</li>
<li>Answers from your site, not the open web. RAG hybrid search grounds replies in your actual posts, pages, and knowledge base, so answers stay on-brand and accurate.</li>
<li>Your data, your bill. Self-hosted: conversations and keys live on your WordPress install, and you pay your AI provider directly with no markup.</li>
<li>No lock-in. Switch between OpenAI, Claude, Gemini, and OpenRouter whenever you want.</li>
<li>Speaks your visitors’ language. Automatic multi-language replies, so one bot serves an international audience.</li>
</ul>
<h4>What it does</h4>
<ul>
<li>Bring your own key: OpenAI, Anthropic Claude, Google Gemini, or OpenRouter, switchable per site.</li>
<li>Site learning: indexes your posts and pages so the bot answers from your content.</li>
<li>Knowledge base: add Q&A or upload PDF/DOCX files, with priority over general answers.</li>
<li>RAG hybrid search: combines keyword and semantic retrieval for grounded replies.</li>
<li>Web search: lets the bot pull current information when configured.</li>
<li>MCP tools: exposes 5 Model Context Protocol tools, so agents such as Claude or ChatGPT can read and act on your site through conversation.</li>
<li>Usage dashboard: tracks conversations, messages, and API cost.</li>
<li>Gutenberg block: drop the chatbot into any page or post.</li>
</ul>
<h4>Self-hosted and private</h4>
Conversations and keys stay on your own WordPress install. You are billed by your AI provider directly, so cost is transparent and there is no markup.
<h4>Free and Pro</h4>
The free version covers the full chatbot, site learning, knowledge base, RAG, MCP, and the usage dashboard. Pro adds lead capture automation and RAG hybrid search fine-tuning.
<h4>Up and running in about 5 minutes (free, no credit card)</h4>
You do not need an API key or any AI experience to start. On first setup the plugin shows a “Start for free” panel with two no-credit-card paths: an OpenRouter free key or a Google Gemini free-tier key.
<ol>
<li>Pick OpenRouter or Gemini.</li>
<li>Click through to get a free key (about a minute) and paste it in.</li>
<li>Press Test Connection — the key is validated and saved, a working free model is auto-selected, and the chatbot is switched on.</li>
</ol>
That’s it. Each option states its data-handling trade-off up front (the Gemini free tier may use submitted content to improve Google’s models), so you choose with eyes open. You can switch to your own OpenAI, Claude, or Gemini key at any time.
