Add a voice AI agent
to any website

Zai is an embeddable voice widget powered by Gemini Live. One script tag gives your site a real-time AI phone agent that knows your content, captures leads, and talks to visitors naturally.

How it works

Single WebSocket, zero latency

The widget connects via WebRTC to a Pipecat voice pipeline backed by Gemini Live — a single bidirectional WebSocket that handles speech-to-text, reasoning, and text-to-speech with no inter-service hops.

🌐

Site-Aware Context

Fetches your AI sitemap and bakes every page into the system prompt so Zai knows your content cold.

⚡

Real-Time Voice

Gemini Live streams audio in and out over a single WebSocket — sub-second response times.

📋

Lead Capture

Zai naturally collects name, email, phone, and consent during conversation via function calls.

🔨

One Script Tag

Drop a single <script> tag on any page. No build step, no framework dependency.

Quick start

Three steps to go live

Create an AI sitemap

Publish a JSON file at /ai-sitemap.json listing the pages you want Zai to know about.

Add the script tag

Paste the embed snippet before </body>. Set your sitemap URL and site name via data attributes.

Talk to your site

A call button appears in the bottom-right corner. Click it and start a voice conversation with your site's AI.

Embed code

Copy & paste this snippet

Place this before the closing </body> tag on any page where you want the voice widget.

HTML

<!-- Zai Voice Widget -->
<script

  data-sitemap-url="https://yoursite.com/ai-sitemap.json"
