Works on Any Website

Add Voice AI to Any Website

Copy one line of HTML, paste it before your closing </body> tag, and your site has a voice assistant. Visitors click, allow the mic, and talk in real time. No framework, no plugins, no build step—works on any static site, CMS, or custom stack.

How the Embed Code Works

One script tag, voice AI everywhere

Visitor Clicks the Button

A floating voice button appears on your page. Anyone can click it to start a conversation—no sign-up required.

Browser Audio via WebRTC

The visitor allows the microphone and speaks. Audio runs through the browser—no phone call, no plugin, no download.

Your Agent Responds

Your configured voice agent answers questions, books appointments, and captures leads in real time.

Isolated Shadow DOM

The widget renders in an isolated Shadow DOM, so it never clashes with your site's existing CSS or JavaScript.

Add the Embed Code

Copy, paste, done

1

Copy the Script Tag

Grab your one-line embed code: <script src="https://app.edesy.ai/widget/voice-widget.js" data-api-key="wk_live_xxx" async></script>. Set data-api-key to your widget key, and optionally add data-position.

2

Paste Before </body>

Open your index.html or site template and paste the script just before the closing </body> tag. That is the only edit you need to make.

3

Save and Reload

Save the file, deploy or refresh, and the floating voice button appears. It works the same on static sites, any CMS, and any framework.
