OriginalUploadDate is a Chrome extension designed to provide users with the original publication dates of YouTube videos, distinguishing between actual creation dates and reuploads. This tool is particularly beneficial for researchers, content creators, and journalists seeking to understand the true origins of viral content. The extension employs a proprietary algorithm that analyzes video descriptions, titles, and metadata to detect the earliest possible creation date, ensuring accuracy even with reuploaded videos.

Key features include smart date detection, reupload identification, and confidence scoring to indicate the accuracy of the detected date. Users can enjoy instant results directly on YouTube video pages, enhancing the browsing experience. The extension is free to use with limitations on daily analyses, while premium options offer expanded capabilities such as unlimited analyses and API access, catering to various user needs.
