What feature of interactive whiteboards allows users to save content for future use?

The feature that enables users to save content for future use is automatic saving of text and drawings. This functionality allows users to capture everything that is displayed on the interactive whiteboard, including notes, diagrams, and drawings, which can be preserved for later reference. This is particularly useful in educational settings, where lessons can be saved and revisited by both teachers and students.

While real-time editing allows users to make changes and updates instantly, it does not specifically relate to the saving of content for future use. Video recording of sessions is focused on capturing the entire session as a video, which is different from saving individual pieces of written content. Cloud storage integration can facilitate the saving and sharing of content, but it is not an inherent function of the interactive whiteboard itself that handles automatic saving directly. Thus, the most direct and relevant feature for saving content created during an interactive session is indeed the automatic saving of text and drawings.
