SponsorBlock is an open-source, crowdsourced browser extension designed to make watching YouTube videos smoother by automatically skipping sponsor segments. Instead of sitting through ads embedded by creators, users can submit timestamps of sponsor parts directly through the extension. Once verified, these segments are shared via an open API, allowing the extension to skip them automatically during playback.
Besides sponsors, SponsorBlock also recognizes other common interruptions such as intros, outros, and subscription reminders, and it even helps jump to highlighted points within a video. Its privacy-preserving system ensures users’ viewing habits stay safe while enjoying a more seamless experience.
