Brilliant!

Such a great extension, didn't think such a thing could be done... Amazing Ajay

It doesn't skip anything and the servers doesn't work.
Edit: It works flawlessly 2025

Brilliant when it's working, but relies on a server that is down more often than not.

will skip sponsors, but cannot submit my own sponsor segments to skip

My favorite add-on for Youtube, hands down. It has improved my experience so much, from watching science videos to listening to music. The amount of customization over individual categories makes this suitable for just about anyone, and I've been recommending SponsorBlock to everyone I know. I also find it satisfying to mark out new segments and know it's saving time for others, just like someone's segments are saving me.

While the downtime lately has been pretty rough, I have to imagine that it's either because of the new changes to YouTube or they are intentionally doing something to harm this app since 233k people are automatically skipping sponsors. This has to be doing things YouTube doesn't like, but they can eat shit. Ajay's extension has worked very well for most of the length of time that I've used it and I feel like he's trying to fix whatever the current issue is. It's saved me from watching hours of terrible normally unblockable advertisements and I'm grateful the work that's already gone into making that possible.

I swear to God. Nearly constant "Error Code 503" lately.

Interesting idea but this app is rapidly going from half useless to utterly useless.

Its a good add-on but its down 1-2 days a week please fix this.That will be all , thank you for your time.
