Stickon is a versatile Chrome extension designed for effective online note-taking and collaboration. It allows users to attach private or shared annotations directly to web page content, ensuring that notes remain anchored to specific elements regardless of layout changes. This feature is particularly useful for study groups, design feedback, and research purposes, as it enables users to highlight key points and engage in discussions in real-time. The extension is free to use and is ad-free, focusing solely on enhancing user experience.

Privacy is a core aspect of Stickon, as notes are private by default and only become visible to selected friends when shared. Users can easily manage their notes and shared connections through the Profile tab, where they can delete notes or remove friends at any time. Real-time updates ensure that all collaborators stay informed without needing to refresh the page. Overall, Stickon is a valuable tool for anyone looking to enhance their online interactions with targeted annotations.
