<p>Most WordPress AI chatbots are text boxes. <strong>AI Avatar gives your visitors a real 3D digital human</strong> they can talk to with voice — the avatar lip-syncs in real time and replies with natural-sounding speech.</p>
<h4>Two ways to use</h4>
<ul>
<li><strong>Demo mode</strong> (this plugin’s default) — Quick evaluation with our hosted demo LLM. Paste the API Key, the chat bubble shows up. No coding required. Ideal for evaluating the 3D avatar quality and the conversation UX.</li>
<li><strong>Production mode</strong> — Plug in your own LLM (OpenAI, Claude, internal API) via our <a href="https://www.npmjs.com/package/@ai-avatar/embed-sdk" rel="nofollow ugc">JavaScript SDK</a> in <code>external</code> mode. You keep full control over the conversation logic and data flow; the plugin / SDK only handles the 3D avatar rendering, lip-sync, and voice I/O.</li>
</ul>
<p>Most production deployments use <strong>Production mode</strong> so visitor messages never touch our LLM and stay within your existing chat / support stack. The plugin’s bundled chat exists for fast first-impression demos.</p>
<h4>Why a 3D avatar?</h4>
<ul>
<li><strong>More engaging than text</strong> — visitors talk longer, ask more questions, convert better</li>
<li><strong>Voice in / voice out</strong> — natural conversation, not typing</li>
<li><strong>Real-time lip-sync</strong> — the avatar’s mouth matches the speech, not a cheap GIF</li>
<li><strong>Drop-in</strong> — one API Key in settings, the bubble shows up in 3 minutes</li>
</ul>
<h4>Features</h4>
<ul>
<li>One-click embed via WordPress admin — no code editing</li>
<li>Configurable position (4 corners), theme (light/dark/auto), primary color, size</li>
<li><code>[yuji_ai_avatar]</code> shortcode for per-page placement</li>
<li>Site-wide auto-inject with per-page exclusion list</li>
<li>Auto-detects WordPress site language — UI follows your site’s locale</li>
<li>Bundled English + Simplified Chinese translations</li>
<li>Async script loading — does not slow down your site</li>
<li>No tracking, no admin nags, no “Upgrade to Pro” popups</li>
</ul>
<h4>How it works</h4>
<ol>
<li>Install and activate the plugin</li>
<li>Sign up at <a href="https://avataraisdk.com" rel="nofollow ugc">avataraisdk.com</a> and create an avatar</li>
<li>Paste your API Key into <strong>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> AI Avatar</strong></li>
<li>Done — the chat bubble appears in the corner of your site</li>
</ol>
<h4>Pricing</h4>
<p>The plugin is free and open source (GPLv2). The AI Avatar service has a free tier; paid plans scale with conversation volume. See <a href="https://avataraisdk.com/pricing" rel="nofollow ugc">pricing</a>.</p>

<p>NavTalk Digital Human is a WordPress plugin that enables you to embed interactive AI avatars on your website. Users can have real-time voice and video conversations with AI-powered digital humans directly from your WordPress pages. This plugin is not affiliated with or endorsed by WordPress.</p>
<p>The plugin itself is free and the full plugin code is included in this package. Avatar and conversation features are provided by the NavTalk cloud service (Software as a Service); a NavTalk account and license key are required to use that service—this is not hidden or trial-locked code inside the plugin.</p>
<h4>Features</h4>
<ul>
<li>Simple Configuration: Only requires a license key to get started</li>
<li>Multiple Avatars: Support for multiple digital human avatars</li>
<li>Real-time Communication: WebSocket and WebRTC powered conversations</li>
<li>Voice Interaction: Full duplex voice communication</li>
<li>Video Streaming: Real-time video of digital human responses</li>
<li>Responsive Design: Works on desktop and mobile devices</li>
<li>Customizable: Adjustable card dimensions and button text</li>
<li>Secure: License-based authentication</li>

</ul>
<h4>Requirements</h4>
<ul>
<li>WordPress 5.0 or higher</li>

<li>Modern web browser with WebRTC support</li>
<li>HTTPS enabled (required for microphone access)</li>
<li>NavTalk account and license key</li>
</ul>

<p>For support, documentation, and updates, visit:<br />
* Website: https://navtalk.ai<br />
* Documentation: https://docs.navtalk.ai<br />
* Support: support@navtalk.ai</p>
<h3>Privacy Policy</h3>
<p>This plugin does not collect or store visitor personal data in the WordPress database. The site administrator stores the NavTalk license key in WordPress options. When visitors use the digital human, audio, video, and chat-related data are processed by NavTalk’s services as described below.</p>
<h3>External services</h3>
<p>This plugin connects the visitor’s browser and your WordPress site to NavTalk (operated by NavTalk / navtalk.ai) to load avatars and run real-time conversations.</p>
<ul>
<li>HTTPS REST API (<code>https://api.navtalk.ai</code>): Used when the plugin or wp-admin requests avatar lists, avatar details, and connection tests. Requests send your license key in HTTP headers and may receive avatar metadata and media URLs.</li>
<li>WebSocket (<code>wss://transfer.navtalk.ai</code>): Used during an active session for real-time voice/video and messaging between the visitor’s browser and NavTalk.</li>
<li>Media delivery: Avatar images and preview videos are loaded from URLs returned by the API (for example from NavTalk CDN hosts such as <code>https://cdn.navtalk.ai</code>). The browser requests those assets directly.</li>
</ul>
<p>Data sent to NavTalk includes at least your license key (from WordPress), session-related traffic over WebSocket (including voice/video where the user grants browser permissions), and any prompts or configuration you set in the plugin. What NavTalk logs or retains is governed by their policies.</p>
<p>Official policies (review before use):<br />

* Privacy Policy: https://navtalk.ai/policy/privacy-policy/</p>
<h3>Third Party Services</h3>
<p>Same as “External services” above: the plugin depends on NavTalk API, WebSocket, and related media hosts. See that section for endpoints, data flow, and policy links.</p>
