yTeaser
What it is
yTeaser accepts a YouTube link and returns an AI summary with three takeaways, each under 100 characters. It detects the video's language and summarizes in that language, while translating non-English videos into English. Optional sentiment analysis grades reactions in top comments from A+ to F. The web app and Chrome extension provide access; the extension adds a summary button to YouTube thumbnails and displays results inline. A REST API offers video summarization and English-translation endpoints, limited to 20 and 30 requests per minute respectively. The Slack bot can spot YouTube links in channels and reply in message threads, although the site says it is awaiting Slack review and approval. The free plan requires no account and allows 10 summaries per day. Pro allows 50 summaries daily and priority support at $1.99 a month or $9.90 a year. yTeaser processes submitted URLs and public video information and says it does not store summaries or personal data. It accepts links, not uploads; summaries may fail for private, age-restricted, removed, or very short videos.
