What is SponsorBlock?

SponsorBlock is a free, community-built database of the parts of YouTube videos that viewers mark: sponsor reads, self-promotion, reminders to like and subscribe, intros, end cards and more. Its browser extension skips those parts as you watch. Viewers vote on each segment, so wrong ones drop out over time.

Tool description

Paste a YouTube link or video ID and the video plays right here, with SponsorBlock's segments skipped as they come up and no extension needed. Pick which categories to skip. Sponsor, Unpaid/Self Promotion and Interaction Reminder are checked at first, and you can add intros, end cards, previews, hooks, filler tangents and the non-music parts of music videos. The table next to the video lists every segment with its start and end, highlights the one playing, and plays any segment you click. After a skip, the Unskip button goes back and plays what was skipped.

Features

  • Skip categories you pick, remembered in your browser for your next visit
  • Segment table that highlights the playing segment and plays any segment you click
  • Unskip button and a running total of the time skipped

Good to know

  • SponsorBlock never learns which video you're watching. Only the first four characters of the video ID's SHA-256 hash are sent, and SponsorBlock answers with the segments of every video that shares them.
  • Segments of unchecked categories stay in the table in grey, so you can see them without skipping them.
  • Some segments mute the sound instead of skipping. They're marked Mute in the table, and the sound comes back when the segment ends.
  • A highlight marks the best moment of a video. It's never skipped, but a click on it in the table jumps there.
  • When SponsorBlock labels the whole video, for example as sponsored, the note above the table says so.
  • Segments are added by viewers, so new videos often have none yet. A video without segments plays as usual, and so does any video while SponsorBlock can't be reached.
