We’re excited to launch the Retell Chat Agent, now live for all users!

You can now bring real-time AI automation to your web chat with an embedded AI chat agent directly to your site using the new Retell Chat Widget, powered by the same high precision agent builder behind our voice agents.

What's New

Standalone Chat Agent built for live web chat

Embeddable Chat Widget to integrate with any site using public key.

Why We Built Chat Agents

AI voice agents have transformed how businesses handle phone conversations, but it’s not enough. In reality, communication is rarely limited to just calling, with customers often starting interactions by browsing a site, opening chat bubbles all with the expectation of immediate answers.

But most web chat systems are still stuck in the past. They’re rigid, decision-tree bots with limited memory, no real language understanding, and little flexibility when things go off-script.

We built the Retell Chat Agent to change that.

Now you can automate the smartest web chat experience for your site using the same dynamic logic, real-time memory, and LLM orchestration behind our voice agents, all through an embeddable widget, no extra tooling required.

How To Start

Chat Agents can be created in two ways: converting from existing voice agent and creating an entirely new agent

How To Build a New Chat Agent

Navigate to the Retell Agent Builder

1. Click “Create New Agent”

2. Select your agent type

Add nodes and build out prompting or conversation flow just like AI voice agents

Use variables like {{first_name}}, {{email}}, {{booking_time}}, and more to personalize messages based on user data or previous call context. Ensure all AI chat settings are set to your requirements. Test your conversation flow using Manual Chat or AI Simulated Chat.

See docs for a deeper look into building and integrating Retell AI Chat Agent

How To Create Chat Agent From Voice Agent

Loving the performance of your voice agents? Creating a chat agent with the exact logic, LLM orchestration, and conversation flow is as easy as one click.

1. Go into AI Voice Agent Builder. Click the three dots (···) button. Click Convert to Voice Agent button

How To Embed Retell AI Chat Widget On Site

The widget is embeddable via a single <script> tag and uses the Retell public key system, allowing direct API calls from the frontend with no backend proxy required.

Ensure you have the following information to embed the chat widget: Retell Public Key, Chat Agent ID, Agent Versions.

Create Public Key

In Retell AI Dashboard click on Keys in the left menu. Click on top right + Add Key and select Public Key. Input the name of the key and the site domain you will be embedding the widget on, then Save. See our docs to learn more about Retell public keys.

Embed Chat Widget

Add the following script tag to your HTML, in the head tag:

<script
  id="retell-widget"
  src="https://dashboard.retellai.com/retell-widget.js"
  type="module"
  data-public-key="YOUR_RETELL_PUBLIC_KEY"
  data-agent-id="YOUR_RETELL_CHAT_AGENT_ID"
  data-agent-version="0"
