Beyond text. Conversational digital humans interacting face-to-face in real time.

Real-time face-to-face communication surpasses static text chatbots

For customer kiosks, VIP concierge services, and 1:1 online education, text-only chatbots struggle to establish trust and emotional resonance. Existing commercial video generation platforms (such as HeyGen or D-ID) require batch rendering taking 30–120 seconds per response, rendering genuine real-time conversation impossible.

Giz AI Human unites ultra-low-latency WebRTC P2P video streaming, 180ms debounced double-buffering video renderers, and on-premise MuseTalk lipsync workers to deliver seamless, real-time face-to-face interactions identical to an actual video call.

4 Engineering Pillars of Giz AI Human

Engineering Domain	Giz AI Human Architecture	Operational & Business Value
WebRTC P2P Ultra-Low Latency	PeerJS mesh network with deterministic peer IDs (giz-${user.id})	Sub-200ms round-trip latency for natural, bidirectional audio and video exchanges
Zero-Flicker Double-Buffering	useAgentVideoStreams.ts with 180ms debounced background pre-buffering	Completely eliminates black screen flashes during track swaps for fluid facial expressions
On-Premise MuseTalk Lipsync	Real-time landmark alignment workers running on dedicated RTX 5090 fleets	Eliminates external cloud API costs ($/min) while keeping biometric data 100% on-premise
Persona & Speech Tuning Studio	AgentCharacterEditorDialog.vue visual editor for appearance, tone, and pitch	Customizes branded AI bankers, educators, and enterprise brand ambassadors

3-Stage Real-Time Interaction Pipeline

1. Ultra-Fast VAD & Streaming STT: Web Audio API captures microphone speech, streaming audio chunks to on-premise Whisper workers in real time.
2. Inference & Audio Synthesis: As soon as LLM inference produces initial tokens, on-premise TTS engines immediately begin speech playback.
3. Double-Buffered Lipsync Swap: The browser pre-buffers synthesized video chunks in background elements, smoothly swapping to the active viewport within 180ms.
