MouseKit is a Windows application that enhances presentations and visual communication through cursor visualization and interactive tools. It creates a customizable visual trail following cursor movements, with adjustable duration and length. The Guardian function pulses when the mouse is idle, preventing accidental clicks during pauses. A context bar near screen edges provides quick access to tools without opening the main panel. Seven pre-configured profiles adapt settings for tasks like work, presentations, or gaming. The presentation timer changes color as time progresses, turning yellow at twenty percent and red with pulsing at ten percent remaining. Drawing tools support shapes, text, and magnification directly on screen, while the spotlight feature dims the screen except for a circle around the cursor, directing attention. Additional features include keystroke display, a screenshot tool, and a colored cursor option for improved visibility during recordings or livestreams.
