AI Avatars That See, Hear &
Respond in Real Time
Deploy hyper-realistic AI avatar assistants that recognize faces, detect emotions, understand gestures, and hold intelligent conversations — all streamed live to any screen via WebRTC.
Everything Your AI Avatar Needs to Shine
A vertically integrated stack — from GPU inference to WebRTC delivery — so you deploy in days, not months.
Custom Avatar Creation
Upload photos or videos to generate your own lifelike AI avatar powered by MuseTalk V15. Each avatar is stored securely in S3 and cached on GPU workers for zero-cold-start rendering.
MuseTalk V15 inferenceReal-Time Face Recognition
Identify registered members the moment they appear on camera. The avatar greets them by name and personalizes the conversation using their stored profile context.
Zero-latency identificationEmotion Detection
Detect happiness, sadness, surprise, anger, fear and more with >90% accuracy. The AI adapts its tone, pacing, and response content to match the visitor's emotional state.
10+ emotion statesGesture Detection
Wave to greet, point to direct, or use custom hand signals to trigger specific AI responses and workflows — all processed in real time from the camera feed.
Custom gesture triggersRAG Knowledge Base
Upload your business documents, FAQs, product catalogs, and policies. The avatar retrieves relevant context using vector embeddings (OpenAI text-embedding-3-small) and answers accurately.
Vector-powered retrievalMultilingual Support
Switch between Vietnamese and English mid-conversation. Language is detected automatically per session setup. Built-in prompting ensures culturally appropriate responses.
Auto language detectionLow-Latency WebRTC Streaming
LiveKit-powered peer-to-peer video delivery ensures avatar frames and audio reach your users in under 200ms globally. No plugins, no downloads — pure browser WebRTC.
<200ms end-to-endEnterprise Configuration
Per-setup feature toggles let each client enable/disable face recognition, gestures, emotion detection independently. Redis-hot-reload pushes config changes without restarting sessions.
Hot-reload configGo Live in 4 Steps
From upload to live stream — VisionAI handles the infrastructure so you focus on the experience.
Create Your Avatar
Upload a reference photo or video. Our MuseTalk V15 pipeline processes it on GPU and stores the avatar assets in S3. A thumbnail is generated and cached for instant display.
POST /api/avatar/upload
{ name: "John", file: <mp4> }
// MuseTalk processes → S3 stored
// avatarId: "a3f9c2d1-..."Configure Your Assistant
Choose an assistant type (receptionist, family, sales), write system & behavior prompts, upload your knowledge base documents, and enable the features your use case needs.
PATCH /api/setup/12
{
avatarId: 7,
language: "vi",
features: {
face_recognition: true,
emotion_detection: true
}
}Start a Live Session
Call initSession() — a LiveKit room is created, your config is pushed to Redis, and the worker joins with the avatar pre-loaded. The WebRTC stream starts in under 2 seconds.
POST /api/avatar/init-session
→ Redis: session:{roomName}:config
→ Worker joins LiveKit room
→ Avatar idle loop starts
→ roomName + token returnedReal-Time Interaction
Your customer sees the avatar live. Face recognition fires on entry, emotions are tracked frame-by-frame, gestures trigger custom workflows, and the avatar speaks via STT → LLM → TTS pipeline.
// On presence_detected:
avatar.greet("Xin chào, Minh!")
// On gesture:wave → trigger FAQ
// On emotion:sad → switch tone
// LLM → TTS → lip-sync framesSystem Architecture
One Platform, Every Industry
From retail kiosks to hospital check-ins — VisionAI adapts to your vertical with zero code changes.
AI Receptionist
Greet visitors by name the moment they walk in. The avatar checks appointments, issues badges, and directs guests — all without human intervention.
In-Store Assistant
Customers approach a kiosk, the avatar detects their emotion, adapts its pitch, answers product questions from your RAG catalog, and upsells — in Vietnamese or English.
Patient Check-In
Guide patients through intake forms via gesture and voice. Face recognition pre-fills known patient data. Emotion detection flags distressed patients for immediate human escalation.
Virtual Tutor
An avatar teacher that adapts to student engagement in real time — if emotion detection shows frustration, it simplifies the explanation and encourages with a smile.
Branch Advisor
Customers walk up to a branch kiosk and interact with an AI advisor that knows their account history, answers product questions via RAG, and escalates complex issues.
Brand Ambassador
A unique branded avatar at your booth or event interacts with hundreds of visitors simultaneously, collects leads, shares promotional content, and logs all interactions.
Simple, Transparent Pricing
No per-minute charges. No seat limits. Just flat monthly plans that scale with your usage.
