Web embed

Put a live, talking avatar on any web page with one iframe.

bitHuman cloudIn the browser (WebGPU)

One URL in an <iframe>: no npm package, no install and no secret in the browser.

Before you start

The embed URL is https://www.bithuman.ai/embed/<CODE>, and the avatar listens and answers. By default it renders in the bitHuman cloud and streams to the page; with render=local it renders in the visitor’s tab with WebGPU.

A current browser. For lip-sync rendered in the tab, a usable GPU (render in the tab).
An agent code: A23WJF0199 (the wise-pup sample avatar) or your own (create your own avatar).
For a private agent, an embed token minted by your server.

Authenticate

A public agent needs no credential. For a private agent, your server mints an embed token with your API secret and passes it to the page. Sessions on your own agent bill your account per second, voice and AI included (pricing).

Run your first avatar

<!doctype html>
<html>
  <body style="margin:0">
    <iframe src="https://www.bithuman.ai/embed/A23WJF0199"
            allow="microphone *" style="width:100%;height:100vh;border:0"></iframe>
  </body>
</html>

Expected: the avatar’s picture with Tap to talk. Select it, allow the microphone, and the avatar greets you and answers when you speak. Keep the * in allow, or the microphone is blocked. To try it without a page, open https://www.bithuman.ai/embed/A23WJF0199.

The wise-pup sample ends each session after 2 minutes. For your site, embed your own agent (create your own avatar); its sessions have no such limit.
