SpoilerCub

SpoilerCub came from a very simple problem: YouTube keeps spoiling things. I’ve had games, movies, and shows ruined by a single thumbnail, title, or comment that appeared before I ever clicked anything. Avoiding YouTube completely isn’t realistic, and existing tools either block too much or don’t go far enough. SpoilerCub is built to focus only on YouTube and block spoilers before you see them. You add the keywords you want to avoid, and the extension automatically protects your home feed, search results, Shorts, playlists, and comments. Instead of removing content entirely, SpoilerCub hides thumbnails and replaces titles with warnings so you stay in control. During development, it became clear that spoilers don’t come from just one place. Early versions only handled search, but testing showed that recommendations, Shorts, and comments were the biggest offenders. That feedback shaped SpoilerCub into a full YouTube-wide protection layer rather than a single-feature extension. SpoilerCub will be entering beta very soon. The beta phase will be focused on improving accuracy, performance, and usability based on real user feedback before the public release. I’d really appreciate any feedback: What part of YouTube spoils content for you most often? What would make a spoiler blocker actually useful for you? Thanks for checking it out.
