DrawPen is a free, open-source screen annotation application designed for drawing directly over desktop content. It provides a transparent overlay for highlighting information during presentations, tutorials, and demonstrations. Users can draw with brushes, pens, highlighters, and geometric shapes without modifying underlying applications. The software includes text annotations, arrows, an eraser, and a laser pointer for temporary emphasis. A whiteboard mode provides an alternative surface for explaining ideas. Keyboard shortcuts allow quick switching between drawing tools and normal pointer interaction. Users can adjust drawing colors and line thickness while clearing annotations when needed. Built with Electron, DrawPen is available for Windows, macOS, and Linux.
