Yuji AI Avatar — 3D Digital Human Chat Widget

Most WordPress AI chatbots are text boxes. AI Avatar gives your visitors a real 3D digital human they can talk to with voice — the avatar lip-syncs in real time and replies with natural-sounding speech.

Two ways to use

• Demo mode (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.
• Production mode — Plug in your own LLM (OpenAI, Claude, internal API) via our JavaScript SDK in external 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.

Most production deployments use Production mode 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.

Why a 3D avatar?

• More engaging than text — visitors talk longer, ask more questions, convert better
• Voice in / voice out — natural conversation, not typing
• Real-time lip-sync — the avatar’s mouth matches the speech, not a cheap GIF
• Drop-in — one API Key in settings, the bubble shows up in 3 minutes

Features

• One-click embed via WordPress admin — no code editing
• Configurable position (4 corners), theme (light/dark/auto), primary color, size
• [yuji_ai_avatar] shortcode for per-page placement
• Site-wide auto-inject with per-page exclusion list
• Auto-detects WordPress site language — UI follows your site’s locale
• Bundled English + Simplified Chinese translations
• Async script loading — does not slow down your site
• No tracking, no admin nags, no « Upgrade to Pro » popups

How it works

1. Install and activate the plugin
