Drawing instruments

The included graphics editor allows users to insert geometric shapes into the workspace. There is a color selector as well. The line thickness is customizable. All projects can be managed in the Gallery section.

Similar to Real ChalkBoard, a blackboard background image for an old-fashioned classroom effect is included. You can enable dark mode as well.

Additional capabilities

There is an infinite page setting that lets users draw any amount of images without worrying about running out of space. The workspace is naturally partitioned into page-sized chunks. It is possible to export and share the results with other people over the network.

Another useful feature is importing and annotating multi-page PDF documents. This functionality is helpful for grading student papers and researching various topics.
