For those who don't know, SponsorBlock skips segments based on crowd-sourced timestamps. You can also (optionally) mark/skip intros, outros, like/subscribe begging, etc.
No, it's called Sponsor Slice. I'm debating even putting it on the chrome store, it was a fun little side project for me, but I think it will be expensive to run (using gpt-4.0-mini). Also I don't think people will like the idea of sending me the ID's of the videos they are watching, but who knows, maybe if they dislike sponsored segments as much as I do they would be willing.
