How many times have you heard “this video is sponsored by”? In-video sponsor reads got longer than actual ads. SponsorBlock skips them all automatically, and you never even notice they were there.

The extension is powered by millions of users who mark where each sponsor segment starts and ends, so when you reach it, you jump right past it. Completely free and open source.
What is SponsorBlock?
SponsorBlock is a free browser extension to skip YouTube sponsor segments baked inside videos: sponsor reads, subscribe reminders, long intros and outros. It works as a community system: one user marks the segment once, and millions of users after them skip it automatically.
How to use it
- Install the extension from the Chrome or Firefox store (search SponsorBlock).
- Open any YouTube video with a sponsor read.
- You will notice colored parts on the progress bar: those are marked segments.
- When the video reaches them, they skip automatically with zero clicks.
Why it stands out
- Fully automatic skipping: nothing to press.
- You control the categories: sponsors only, or intros and outros too.
- Works on Chrome, Firefox and Edge, and on Android through apps like ReVanced.
- Completely free and open source.
How much time does it actually save?
The extension counts the time it saved you, and many users discover they save whole hours every month. If you watch an hour of YouTube daily, sponsor reads eat minutes every single day, and learning to skip YouTube sponsor segments automatically gives all of it back.
Frequently asked questions
Does it block regular YouTube ads?
No, it skips segments baked inside the video itself (sponsor reads). For YouTube ads you need a separate ad blocker.
Does it hurt the creator?
The segment is skipped after the view already counts, and the choice is ultimately yours.
Does it work on mobile?
On Android yes, through modified apps or extension-friendly browsers. On iPhone options are limited.
