What yTeaser is

yTeaser turns a YouTube link into a short AI summary with three takeaways, each under 100 characters. It detects the video's language and summarizes in that language, while also translating non-English videos into English. Optional sentiment analysis grades the reaction in top comments from A+ to F. The web app and Chrome extension are available; the extension adds a summary button to YouTube thumbnails and shows results inline. Its REST API offers video summarization and English translation endpoints, limited to 20 and 30 requests per minute respectively. A Slack bot can reply to YouTube links in message threads, but the site says it is awaiting Slack review and approval. The free plan provides 10 summaries per day without an account. Pro allows 50 summaries per day and priority support for $1.99 a month or $9.90 a year. yTeaser processes submitted links and publicly available video information; its privacy policy says it does not store summaries or personal data. It accepts YouTube links, not video uploads. Summarization may fail for private, age-restricted, removed, or very short videos with little metadata.
