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>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>

Ethora Chat Assistant adds an AI chat widget to your WordPress site. The assistant reads your own pages and uses them to answer visitor questions, so when someone asks about your product, your pricing, or how to get in touch, they get a real answer instead of a generic contact form.
<h4>Set it up in one click</h4>
The plugin includes a Set Up Automatically button. Click it, sign up for a free Ethora account inside the popup, confirm your site URL, and the plugin will:
<ol>
<li>Create your Ethora account.</li>
<li>Provision an AI assistant configured for your site.</li>
<li>Crawl up to 100 of your pages so the assistant can answer questions about them.</li>
<li>Save the assistant’s App ID into your plugin settings automatically.</li>
</ol>
The widget is live on your site as soon as the wizard finishes. Total time: roughly a minute.
Already have an Ethora App ID? Paste it into the settings field instead – both flows produce the same result.
<h4>What you get</h4>
<ul>
<li>A chat launcher on every page of your site (header or footer placement).</li>
<li>Answers grounded in your own content – the assistant cites what it knows from your indexed pages instead of making things up.</li>
<li>A free Ethora admin panel where you can edit the assistant’s prompt, change its name and avatar, re-index your pages after you update them, and review past visitor conversations.</li>
<li>Mobile-responsive widget that works on every screen size.</li>
<li>Optional Google Sign-In so returning visitors keep their chat history.</li>
</ul>
<h4>Typical use cases</h4>
<ul>
<li>Product and SaaS sites – “what does your tool do, how much, how do I integrate it?”</li>
<li>Documentation sites – the assistant answers from your docs.</li>
<li>E-commerce – shoppers ask about shipping, returns, sizing.</li>
<li>Customer support and help centres – first-line triage before a human steps in.</li>
<li>Lead generation and pre-sales – answer FAQs, capture warm leads.</li>
</ul>
<h4>How it works behind the scenes</h4>
The widget JavaScript is bundled with the plugin and served from your own WordPress site (no remote script host). At runtime the widget connects to the Ethora chat / AI service to provision a chat session and stream responses. The full list of third-party services it contacts is in External services below.
The “Set Up Automatically” wizard runs in a popup on the Ethora admin domain (app.chat.ethora.com). When it finishes it sends only the new App ID back to your WordPress site via the browser’s <code>postMessage</code> API, and your WordPress site saves it to the plugin settings. No Ethora credentials are stored in WordPress.
<h3>External services</h3>
This plugin embeds the Ethora chat / AI assistant. Once you set an App ID and a visitor opens the chat, the widget connects to the following third-party services. No data is sent to these services until a visitor interacts with the chat widget.
1. Ethora chat & AI service (provided by Dappros Ltd, trading as Ethora) 
– Purpose: deliver real-time messaging, authenticate the chat session, and return AI assistant responses. 
– Data sent: chat messages, the configured App ID, session/authentication tokens, and basic profile data for signed-in users. 
– When: while a visitor uses the chat widget. 
– Service endpoints: Ethora REST API and XMPP real-time messaging servers on ethora.com domains. 
– Provider: https://ethora.com 
– Terms of Service: https://wiki.ethora.com/wiki/Info:Privacy_policy#Terms_of_Service 
– Privacy Policy: https://wiki.ethora.com/wiki/Info:Privacy_policy
2. Google Sign-In (Google Firebase Authentication / Google OAuth 2.0) 
– Purpose: optional “Sign in with Google” login for chat users. 
– Data sent: email address and basic Google profile information, only when a visitor chooses to sign in with Google. 
– When: during the optional Google sign-in flow. 
– Domains: identitytoolkit.googleapis.com, securetoken.googleapis.com, accounts.google.com. 
– Terms of Service: https://policies.google.com/terms 
– Privacy Policy: https://policies.google.com/privacy
3. LinkPreview (linkpreview.net) 
– Purpose: generate preview cards for URLs shared inside chat messages. 
– Data sent: URLs contained in chat messages. 
– When: when a message contains a link. 
– Provider & Privacy Policy: https://www.linkpreview.net
Profile images for signed-in users may be displayed directly from Google’s user-content servers (lh3.googleusercontent.com).
The Set Up Automatically wizard, when used, additionally exchanges sign-up form data (email, password, first/last name) with the Ethora API to create your Ethora account, and submits your site URL for crawling. This data is sent only when you actively run the wizard.
<h3>Source code</h3>
The chat widget bundled with this plugin is built from Ethora’s open-source code.
<ul>
<li>Plugin source: https://github.com/dappros/ethora-wp-plugin</li>
<li>Chat widget source: https://github.com/dappros/ethora-ai-chat-widget (Vite-built embeddable widget)</li>
<li>The non-minified, human-readable build of the widget is shipped alongside the plugin as <code>assets/js/ethora_assistant.js</code>.</li>
</ul>
The widget is produced with a standard <code>npm install</code> + Vite build from the source repository above; no build step is required to run the plugin.
