Draw over anything

Annotate slides, PDFs, spreadsheets or a website directly, not just inside one app that happens to have a markup feature.

Old marks clear themselves after a few seconds, so the "board" doesn't get cluttered mid-lesson.

Point at exactly what you mean when twenty students are looking at the same shared screen.
