Sketch Over

Sketch Over floats above every app, ready the moment you need it.
Pick up a pencil, pen, brush or marker and draw directly over anything on your screen — presentations, code, designs, videos. Drop a text label, guide your audience with a laser pointer, or cover your screen with a blackboard for teaching and presenting. When you're done, export a perfect PNG that captures your drawings together with everything behind them.
