Real-time talking avatars vs AI video avatars
AI avatars come in two kinds. Video generators turn a script into a video file. Real-time avatars speak live, responding as text arrives. Which one you need depends on whether you are publishing content or having a conversation.

How Liveface differs among real-time avatars
- Made from one photo: no filming session to create the avatar.
- Animated in the visitor's browser: the face runs on the device; only the speech is produced on the server.
- Added with one script tag, driven by any chatbot through Liveface.speak().
- Natural voices in 13 languages, including Arabic and Persian.
How to choose
- You publish content that changes rarely: a video generator.
- Your page or app talks with people, or the words change often: a real-time avatar.
- You want it on your own website, from your own photo, without per-minute conversation fees during the beta: try Liveface.

Questions
What is a real-time talking avatar?
An avatar that speaks text the moment it is given, with lips, eyes and head moving live, instead of a pre-rendered video. It suits conversations, assistants and pages whose words change.
Can a real-time avatar use ChatGPT, Claude or Gemini?
Yes. The language model writes the answer and the avatar speaks it. With Liveface, send the answer to Liveface.speak(), or stream it with Liveface.stream().
