SummaryTube

SummaryTube is an AI summarizer for YouTube videos. A user pastes a video link, or uses the Chrome extension directly on YouTube, and receives a concise structured summary with key moments and a transcript. The tool also answers questions about a video, surfaces top comments, and translates summaries into more than 40 languages, with transcripts available in more than 10. It is aimed at students, researchers and anyone with more video to watch than time to watch it. Sign in is through a Google account. The site also publishes a browsable library of generated summaries grouped by channel and by category, such as Education, Science and Technology, and News and Politics. The service was built and is run by an individual developer based in Kolkata, India. The Free plan costs nothing and has no stated end date. The Pro plan is $2.99 per month, or $24 per year, and adds 1,000 credits per month, unlimited video length, key moments, transcripts, question and answer, top comments, support for more than 25 languages and an ad free experience. A two year pass is sold for a one time payment of $49. The site also advertises a discount code on its upgrade banner.
