Your first faceTypeScript

assistant.ts

import { createFace } from '@allpersonas/core';

export function mountAssistant(host: HTMLElement) {
  host.style.width = '280px';
  host.style.height = '340px';
  const face = createFace(host, {
    avatar: 'ruby',
    expression: 'attentive',
  });

  face.update({ thinking: true });
  // When your agent responds:
  face.update({ thinking: false, expression: 'joyful' });

  // Call the returned function when your view unmounts.
  return () => face.destroy();
}

Call after mounting. Run the returned cleanup when your view unmounts.

Connect your model

Use your existing agent or try OpenAI, Anthropic, or Vercel AI Gateway in the playground with your own key.

Choose your voice

Use browser speech, connect ElevenLabs in the playground, or drive the face from your app’s audio.
