What yTeaser is
yTeaser takes a YouTube link and returns an AI summary containing three extracted takeaways, each under 100 characters. It detects the video language, summarizes in that language, and translates non-English videos into English. Optional sentiment analysis grades reactions in top comments from A+ to F. The web app and Chrome extension are available; the extension places a summary button on YouTube thumbnails and shows results inline. A REST API provides video summarization and English translation endpoints, limited to 20 and 30 requests per minute. A Slack bot can detect YouTube links and reply in message threads, although the site says it is awaiting Slack review and approval. The free plan allows 10 summaries daily without an account. Pro allows 50 daily with priority support for $1.99 a month or $9.90 a year. yTeaser processes submitted URLs and public video information without storing summaries or personal data. It accepts links, not video uploads.
