- ×5 **Interactive / conversational avatars:** This is the defining capability for the page: a real-time, responsive avatar session, not a pre-rendered video file.
- ×4 **Public API:** A live avatar agent has to be embedded into a product or call flow; that only happens through an API, the same way a voice-ai platform gets wired in.
- ×3 **Voice cloning included:** A cloned voice is what makes a live avatar agent sound like a specific person's brand instead of a generic assistant.
- ×3 **BYO-TTS integration:** A conversational avatar stack is usually assembled from parts (LLM, TTS, avatar rendering); how it plugs into an existing voice vendor decides how much has to be rebuilt.
- ×2 **Avatar model (vendor-named):** Realism matters more in a live, sustained conversation than in a 30-second scripted clip, where small artifacts are far more noticeable.
