Tavus enables the creation and deployment of real-time, human-like AI video interactions. Its core is the Conversational Video Interface (CVI), an API-first framework for embedding face-to-face AI conversations into any product. This allows AI agents to see, hear, and respond naturally, mirroring human conversation with ultra-low latency, often under one second for a full interaction. Users create "AI Replicas" or "digital twins" from minutes of training video, capturing voice and facial expressions. These are powered by models like Phoenix for photorealistic faces, Raven for perception, and Sparrow for natural turn-taking. Beyond real-time, Tavus generates personalized videos at scale. Businesses create one template, and AI customizes it for thousands of viewers with unique greetings or recommendations. The platform also converts scripts to video, adding AI-driven voiceovers and customizable templates. Developers utilize a modular AI pipeline with configurable layers for Perception, STT, LLM, and TTS, allowing fine-tuned control. Developer APIs and a React Component Library aid integration. AI agents can integrate knowledge bases for accurate responses and use function calling to interact with external tools like CRMs. Multilingual support for over 30 languages is included, ensuring natural flow with sub-one-second response times. For personal use, Tavus offers PALs (Personal AI Companions), providing lifelike, emotionally intelligent AI companions for various services.
