Make your avatar alive

To make your avatar alive, three different type of services is needed:

An example of connecting a Rive character to Langchain is provided below.


To get this started, You need to provide a audio service API key and put key inside the “AvatarDisplay” tag to make your avatars start talking.

You should also provide a mouth-sync supported avatar and put the url or file inside the “AvatarDisplay” tag.

import { useState } from 'react'
import { useAvatar } from '@avatechai/avatars/react'
import {
} from '@avatechai/avatars/default-loaders'

// you can replace the url with any rive model that support mouth-sync.

const elevenLabs = new ElevenLabVoiceService(

function App() {
  const [text, setText] = useState('');
  const { avatarDisplay, handleFirstInteractionAudio } = useAvatar({
    // Avatar State
    text: text,
    avatarId: 'af3f42c9-d1d7-4e14-bd81-bf2e05fd11a3',

    // Loader + Plugins
    avatarLoaders: defaultAvatarLoaders,
    blendshapesService: defaultBlendshapesService,
    audioService: elevenLabs,

    // Style Props
    scale: 4,
      onClick={() => {
      send it

export default App
