Start with the task, not the tool list
A screen annotation app is most useful when it removes context switching. A teacher may need a quick pen and spotlight over a browser. A trainer may need numbered steps, a curtain, and a timer. A tutorial creator may care more about screenshots, short GIFs, and local recording. The guides in this library begin with those outcomes and explain a compact workflow.
OS Pen runs as a floating Windows workspace over the app you are already using. Essential Pen, Eraser, and Screenshot tools can be started free. Additional precision, presentation, whiteboard, capture, and collaboration tools are available according to the selected plan. Check the current pricing page before deciding which workflow fits your needs.
For a broad product overview, read the screen annotation software guide. For installation, use the signed Windows download page.
