Bring AI agents to life with conversational video

Build conversational experiences that solve real problems
with AI that looks & feels human. Try our Conversational Video Interface.

We're teaching machines the art of conversation


CVI is a new interface that closes the gap between us and machines.

CVI allows you to build video agents that connect and act with precision and empathy, making them capable collaborators. It’s the best of both worlds: the emotional intelligence of humans, with the reach and reliability of machines. They’re available 24/7, in every language, on our terms.

Build any conversational experience. Imagine a therapist that anyone can afford. A personal trainer that adapts to everyone's schedule. A fleet of medical assistants that can give every patient the attention they need.

The fastest, most lifelike human simulation models

CVI mirrors how people see, think, and respond, in real time.

By combining facial rendering, vision, speech, and emotional intelligence, our human simulation models enable face-to-face AI conversations that capture intent, nuance, and presence.

Responses land in under 600 ms, with data retrieval in 30 ms, up to 15× faster than leading RAG systems.

We handle the complexity,
you get conversations that feel real

Real-Time,
Natural Conversations

Create AI-human interactions with natural pacing and rhythm. ~600ms latency keeps responses snappy and turn-taking smooth.

Empathetic
Visual Perception

AI that sees. CVI reads expressions, visual cues, and the environment to engage in a realistic, nuanced way.

Lifelike
AI Replicas

Use 100+ hyper-realistic Stock Replicas or create your own digital twin, complete with subtle micro-expressions.

Multilingual Support

Build once, interact globally. Supports 30+ languages out of the box.

White Label APIs

Seamlessly embed AI video conversations into your platform with simple end-to-end APIs and control your user experience.

Persona Builder

Guided, conversational setup flow that helps you create the ideal role and personality for your CVI, no prompting required.

Memories

CVI remembers past conversations, so follow-ups feel continuous, personal, and informed.

Knowledge Base

Connect to custom data, docs, and APIs for accurate, context-aware answers. With responses within 30 ms, it's 15× faster than other RAG solutions.

Objectives & Guardrails

Set goals and boundaries that guide CVI behavior, keeping every conversation on track and on brand.

Spin up human-AI interactions in minutes

API-first design

Build and test AI video conversations instantly with a flexible, plug-and-play API. No infra management needed.

Plug and play

We handle WebRTC, ASR, VAD, vision, streaming, infrastructure, and more. Right out of the box.

Easily deploy and scale

Deploy AI conversations at any scale without worrying about GPUs, concurrency, or backend complexity.

We lead in research, so you don't have to

CVI is powered by our in-house
human simulation models.
