Screencast Helper is a free Chrome extension developed by Dimanoid that can greatly enhance your video captures of web applications or sites. This handy tool shows a ripple effect on the point where you click with your mouse, making it easier for viewers to follow your actions. Additionally, Screencast Helper offers a "drawing mode" that allows you to draw directly on the screen, highlighting specific areas or adding annotations.

With Screencast Helper, you can easily toggle the drawing mode on and off with a hot key, providing you with the flexibility to annotate your videos as needed. The extension also allows you to customize the size, shape, and color of the ripple effect and brush, giving you full control over the visual elements of your captures.

Whether you're creating video tutorials, demonstrations, or presentations, Screencast Helper is a valuable tool to have in your arsenal. It provides a simple and intuitive way to enhance your web video captures and ensure that your viewers can easily follow along with your actions.
