原文外掛簡介
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
