Focus Mocus is a free Chrome extension that enhances cursor visibility during presentations and screen sharing, particularly when sharing browser windows. This tool is especially beneficial in scenarios where conferencing software does not show the mouse cursor, which can hinder audience engagement. It is also compatible with Google Cast, making it a versatile choice for webinars, virtual meetings, and live training sessions.

The extension offers customizable effects to spotlight the cursor, ensuring that viewers can easily follow along with the presenter's actions. Its seamless integration with various web platforms ensures clarity and focus, making it an essential tool for anyone looking to improve their online presentation experience. Users are advised to test the extension on different webpages, as it is restricted from functioning on the Chrome Web Store domain.
