Extensions are add-ons designed to extend the functionality of the Agora SDK. The Extensions Marketplace is home to extensions that make your app more fun. These extensions provide features such as:

• Audio effects and voice changing.
• Face filters and background removal.
• Live transcription and captioning.

This page shows you how to integrate and use an extension from the Agora Extensions Marketplace.
