Ghost Glass is a free Chrome add-on designed to transform the way users interact with the web by allowing them to leave persistent augmented reality (AR) notes on any webpage. This tool enables users to pin notes, tips, and commentary directly onto specific elements of a webpage, creating a collaborative and interactive experience. The AR Tagging feature ensures that notes remain anchored to their designated spots, even when the page is resized, making it easy for others to see these contributions.

In addition to note-taking, Ghost Glass includes a unique 'Ghost Layer' that reveals notes left by other users, fostering a shared community experience. Users can engage anonymously through generated IDs, while safety measures like a reporting system and mute controls allow for moderation and curation of content. With a focus on community safety, Ghost Glass encourages responsible interactions while enhancing the traditional browsing experience.
