What can I build with AI Avatars?

Use them for onboarding assistants, creative coaches, sales reps, support agents, product-demo hosts, and internal copilots that explain tools in real time.

Are these prerecorded avatar videos?

No. The avatar experience is live and conversational, using Runway's realtime session model so the character can react during the call.

Can I control the avatar personality?

Yes. Each session can be started with a system prompt, greeting, and avatar choice so the agent behaves like a focused product specialist instead of a generic chatbot.

Does this work inside the Quby app?

Yes. The AI Avatars feature is wired into the Expo web app and routed through the same app shell as the rest of Quby.

Do I need to expose my Runway API key in the browser?

No. Session credentials are created server-side through a proxy function, and the client only receives session-scoped credentials for the live call.
