Overview

Tavus is an AI research and product platform for building face-to-face video agents, digital twins, and AI companions. It combines multimodal perception, conversational timing, and real-time rendering so software can see, hear, and respond in a way that feels more natural than text or voice alone.

The product is organized around an API-first Conversational Video Interface (CVI) for developers and enterprise teams, plus PALs for personal AI humans. The workflow shown on the site centers on choosing or training a replica, defining a persona, connecting tools and knowledge, and deploying the agent through API, component, or iframe integrations.

Core capabilities

End-to-end conversational video pipeline

Tavus combines perception, dialogue, and rendering into one conversational video pipeline so teams can build agents that listen, respond, and appear on screen in real time.

Multimodal perception

The platform can interpret facial expressions, tone, gaze, emotion, and ambient context, then use that signal to shape the agent’s response and tool use.

Real-time human rendering

Phoenix-4 generates full-face video with micro-expressions, emotion-driven reactions, and 1080p real-time rendering for a more natural visual presence.

Turn-taking and dialogue flow

Sparrow-1 handles conversational timing, interruptions, pauses, and turn-taking so the agent can keep the flow of a live conversation.

Conversation grounding and control

The knowledge base feature accepts files and websites for retrieval-augmented responses, and the platform also supports memories, objectives, guardrails, and function calling.

Replica creation and deployment

Developers can use stock replicas or train custom replicas from short source video, then deploy them through APIs, React components, iframes, or no-code tools.

Practical use cases

Patient intake and support
Use CVI for intake and qualification flows where an agent needs to notice confusion or distress, adjust its tone, and submit records or next steps through tools during the conversation.
Education and coaching
Use the platform to build tutors or training assistants that remember prior struggles, adapt their responses, and keep context across sessions.
Sales and customer workflows
Deploy a branded sales or support agent that can book meetings, send quotes, pull records, and respond in real time during a face-to-face conversation.
Personal AI companions
Create personal AI humans for ongoing conversation, with voice and video calling, messaging, and multilingual interaction.
High-volume production deployments
Use the platform to build globally deployed interactive agents where real-time video, streaming infrastructure, and concurrency management matter at production scale.
