YouTube Spoiler
YouTube Spoiler is a Chrome extension for previewing YouTube videos before opening them. It is built around the idea of showing a summary from a thumbnail hover, so the viewer can know what a video contains before spending time on it.
The extension presents summaries as clean bullet points and says they arrive in real time. It also supports language translation: a user picks a language once, and each summary is translated instantly into that language, including examples such as Japanese video summaries shown in English and Spanish tutorials read in French. Copying is built in as well; one click copies the summary for pasting into notes, group chats, or Slack. The site also says there are no loading screens and no waiting, and it describes the product as working in 10 seconds.
Delivery is through the Chrome browser, with an Add to Chrome install path. Pricing is stated as free, and the page says no account is needed. The site also notes that it is not affiliated with YouTube or Google.
