# Dify Docs > Dify is an open-source platform for building AI applications. It provides a comprehensive set of tools and features to help you build, deploy, and manage your AI applications. ## Docs - [Configure Annotation Reply](https://docs.dify.ai/api-reference/annotations/configure-annotation-reply.md): Enables or disables the annotation reply feature.
