What is Tavus?
Tavus is an AI platform that enables developers to create hyper-realistic, real-time conversational video experiences through its Conversational Video Interface (CVI). It combines Personas, which define AI behavior, tone, and knowledge via layers like perception and speech recognition, with Replicas, lifelike digital twins trained from just two minutes of video. This allows for human-like interactions where AI can see, hear, respond emotionally, and engage in face-to-face video calls with low latency.
Key features include advanced models like Phoenix for high-fidelity facial rendering, Raven for multimodal perception including emotion detection, and Sparrow for natural conversational flow and turn-taking. Developers can build applications for sales coaching, customer support, interviews, and more, integrating via APIs with support for 30+ languages, knowledge bases, guardrails, and function calling. It also offers batch video generation from scripts and replicas, supporting stock or custom avatars in 42 languages.
Tavus is designed for developers, startups, teams, and enterprises building AI-powered products in sales, support, recruiting, education, and healthcare. Individuals can access PALs, realistic AI companions for personal interaction. The platform scales from free testing to enterprise volumes with pay-as-you-go flexibility.
It emphasizes human computing, bridging the gap between machines and people by teaching AI perception, empathy, and expression for instinctive interactions.
