Question 1

What is SponsorBlock?

Accepted Answer

SponsorBlock is a crowdsourced database where viewers mark sponsor reads, intros, outros, and filler in YouTube videos so others can skip them — over 10 million segments marked to date.

Question 2

How do I check a video?

Accepted Answer

Paste any youtube.com, youtu.be, Shorts, or embed link above (or just the 11-character video ID) and click Check Segments.

Question 3

What do the categories mean?

Accepted Answer

Sponsor is paid promotions, intro/outro are channel bumpers, selfpromo is merch or Patreon plugs, interaction is subscribe begging, and music_offtopic is talking inside music videos.

Question 4

What if it says no segments found?

Accepted Answer

That video simply has no crowdsourced marks yet — common for videos under 50,000 views. You can mark segments yourself with the free SponsorBlock browser extension.

Question 5

Does this skip segments in the video?

Accepted Answer

No — this page only shows the timestamps. Auto-skipping needs the SponsorBlock extension or an app like the Square music client.

Question 6

Is it free without sign-up?

Accepted Answer

Yes — unlimited checks, free with no account.
