YouTube has increasingly become the preferred platform for consuming educational content. To learn complex and intricate concepts, students frequently need to watch several hours of YouTube videos, with an average video length of about 20 minutes. To help users quickly determine whether a video's content is relevant to their needs, the YouTube Video Summarizer was conceptualized. This Chrome extension efficiently generates a summary of a YouTube video using its English-language transcript. By automating this process, the tool enables users to obtain a concise synopsis without spending hours watching the video to assess its relevance.
