CoCite is a Chrome extension designed to enrich YouTube videos by allowing users to add and view citations directly beneath the video. This tool is particularly beneficial for students, researchers, and anyone interested in verifying information, as it connects video content with reliable sources, enhancing the learning experience. Users can easily spot an 'Add Citation' button next to the like button on any video, enabling quick submissions of source links alongside optional tags.

The extension showcases community-contributed citations right below the video title, offering options to upvote the most helpful sources or report any issues. By promoting the sharing of trusted information, CoCite helps users avoid misinformation and fosters a more educational atmosphere on YouTube. As a free, lightweight, and privacy-focused tool, it transforms casual video watching into an opportunity for smarter learning.
