A collaborative whiteboard is a digital canvas where multiple users can interact in real time, making it ideal for brainstorming, teaching, or planning. The core features of such a whiteboard include freehand drawing, which allows you to sketch ideas or annotate visually; adding and editing text, so that notes or labels can be placed anywhere on the canvas; inserting images, enabling you to bring in reference materials or diagrams; and basic layer management, which helps organize and separate different types of content like drawings, text, and images. These features together create a flexible and organized workspace that adapts to a variety of collaborative tasks.
