What is SponsorBlock?

SponsorBlock is a community-driven browser extension and service that tracks user-reported timestamps in YouTube videos where sponsorships, self-promotions, non-music segments, or other types of content appear. Viewers mark these segments as they watch, creating a crowdsourced database that others can use to skip them automatically.

Tool description

The YouTube SponsorBlock Checker lets you look up any YouTube video and see all reported segments in the SponsorBlock database. Enter a YouTube video URL or video ID, and the tool retrieves a detailed table of every marked segment with its category (sponsor, intro, outro, self-promotion, non-music), exact timestamps, vote count, and action type. This is useful for understanding what content has been marked by the community, auditing video quality, or simply previewing what sections are typically skipped.

Examples

For a YouTube video with multiple segments, the tool displays:

  • Sponsor segment: 0:45 to 1:30 (sponsor message, 234 votes)
  • Intro segment: 0:00 to 0:15 (intro animation, 89 votes)
  • Outro segment: 14:20 to 14:50 (end screen, 156 votes)
