Tavus CVI Text Chat Example

A minimal text-only chat interface for Tavus Conversational Video Interface (CVI) that demonstrates sending user messages through the conversation-respond event.

LIVE DEMO

How It Works

This app uses the conversation-respond event to send text messages to Tavus Replicas:

const payload = {
  message_type: "conversation",
  event_type: "conversation.respond",
  conversation_id: currentConversationId,
  properties: {
    text: message
  }
};

callObject.sendAppMessage(payload);

When a user types a message and presses Enter, the app:

1. Captures the text input
2. Wraps it in a conversation-respond event payload
3. Sends it via Daily's sendAppMessage() method
4. The Tavus Replica receives and responds to the message

Quick Start

1. Generate a conversation using the Create Conversation API or Tavus Platform
2. Open index.html in your browser
3. Enter your conversation ID
4. Click "Start Chat" and begin typing messages

Key Features

• Text-only interface (no microphone required)
• Real-time video streaming from Tavus Replica
• URL parameter support (?conversation_id=YOUR_ID)

Built with vanilla HTML/CSS/JavaScript and Daily.co SDK.
