Conversational AI Engine: Create advanced voice apps by combining Agora's real-time audio with powerful conversational AI.

Akool

Akool provides AI-powered avatars with realistic facial expressions and lip-sync capabilities, enabling natural video conversations with your AI agents. Their platform offers a variety of pre-built avatars and supports custom avatar creation.

info

This integration is fully supported for use with Conversational AI Engine. While it has completed functional validation, it is newer to the platform, and additional provider-specific edge cases may be identified as usage scales across a broader range of applications and workloads.
