SpoilerCub

SpoilerCub is a browser extension that protects you from spoilers on YouTube for games, movies, and TV shows. It blocks spoiler content before you see it by hiding thumbnails, replacing video titles with warnings, filtering comments, pausing Shorts, and protecting search results and playlists. You choose the keywords you want to avoid, and SpoilerCub automatically works across YouTube’s home feed, search, recommendations, Shorts, and comments. Instead of forcing you to avoid YouTube entirely, it lets you browse normally without risking major plot reveals. SpoilerCub is focused exclusively on YouTube, allowing for deeper and more reliable spoiler protection than generic content filters. It is currently preparing to enter beta, with early users helping shape accuracy, performance, and features ahead of public release.
