<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>
