Which environment allows editing and creating content in AEM?

The environment that enables users to edit and create content in AEM is the Author environment. This environment is specifically designed for content authors, editors, and marketers to develop and modify content for websites and applications. Within the Author environment, users can utilize the full capabilities of AEM's content management features, including the ability to manipulate digital assets, create and manage pages, and utilize content workflows.

In contrast, the Publish environment is intended for delivering content to the end-users and does not support content creation or editing functionalities, as it serves mainly to serve published content. The Developer environment typically focuses on software development and may include aspects of backend work rather than content management, while the Test environment is generally used for assessing and validating content and functionality before it's moved to production, without allowing for direct content creation or modifications.
