What feature of Sitecore allows content authors to edit web pages directly?

The Experience Editor is the feature in Sitecore that enables content authors to directly edit web pages. This tool provides a user-friendly interface that allows authors to view the website as end users do while still having access to the rich editing capabilities of Sitecore. The Experience Editor enables inline editing, allowing authors to click on editable content areas on the page and modify text, images, and other elements in real-time without needing extensive technical knowledge.

This seamless integration between content management and presentation transforms the content authoring process, making it more intuitive and efficient. Additionally, authors can see their changes in the context of the actual layout and design of the page, which enhances the overall content creation experience.

The Sitecore Editor, while also an editing tool, is more focused on the back-end content management functionalities and doesn't provide the same level of direct page interaction. The Content Manager serves as a robust interface for managing all content items but does not provide the tailored viewing experience that the Experience Editor offers. Page Designer, although it implies direct design capabilities, does not encapsulate the full breadth of inline editing features offered by the Experience Editor.
