Gistil

Gistil tells you if a YouTube video is worth watching before you press play.
It's a free AI YouTube summary extension and app for Chrome, Firefox, iOS and Android: a one-line verdict, a value map of the video, and a button that plays only the useful parts. Skip the intros, sponsor reads and filler, and keep the moments that matter.

Here: short demos, tips, and breakdowns of videos that are (and aren't) worth your time.
