Tavus

Tavus delivers the Conversational Video Interface (CVI), enabling developers to build AI agents with lifelike video presence. The platform creates photorealistic digital replicas from just two minutes of training video, powered by proprietary models: Phoenix for high-fidelity facial rendering with natural micro-expressions, Raven for visual perception and emotion detection, and Sparrow for human-like conversational timing and turn-taking. CVI achieves sub-1-second end-to-end latency for real-time face-to-face conversations where AI can see the user's environment, read expressions, and respond with appropriate emotional intelligence.

The platform supports 30+ languages and integrates with custom LLMs, multiple TTS providers, and knowledge bases for domain-specific conversations. Developers receive a ready-to-use video meeting interface via API that can be embedded into any application. Use cases span AI recruiters, sales agents, tutors, healthcare assistants, and customer support representatives. Tavus handles WebRTC, speech recognition, voice activity detection, and streaming infrastructure, enabling teams to deploy conversational video at scale without managing complex backend systems.

Vapi and Tavus together enable a new dimension of voice AI: face-to-face conversations with AI agents that users can see. While Vapi orchestrates intelligent voice interactions, Tavus adds visual presence through photorealistic digital twins that display natural facial expressions, eye contact, and emotional responsiveness. This combination creates AI agents that communicate across multiple modalities—voice, vision, and video—delivering experiences that feel closer to human interaction than voice alone. Organizations use Vapi with Tavus to build video-enabled customer service agents, AI sales representatives that conduct face-to-face meetings, virtual healthcare assistants, and personalized tutoring systems.

The integration supports scenarios where visual presence increases trust and engagement, such as financial consultations, medical intake, or high-value sales conversations. Tavus's perception capabilities allow agents to understand user context by seeing their environment and reading non-verbal cues, while Vapi's voice AI ensures natural conversational flow. Together, they deliver the emotional intelligence of human interaction with the scalability and availability of AI.
