Hides YouTube's recommended videos if you have already watched them!
Are you sick of seeing recommendations for YouTube videos you have already watched or started, but decided not to finish?
SeenThat! uses YouTube's watch history to hide suggestions for videos that you've already seen.
This extension REQUIRES you to be signed into YouTube and to have watch history unpaused.
You can toggle this at https://www.youtube.com/feed/history.
You can customize hiding from the following pages with one simple menu:
- Home Page
- Watch Page
- Channel Videos
- Search Results
You can further filter the videos by only hiding videos that you've watched past a certain percentage or by hiding playlist recommendations.
SeenThat! does not collect any user data, but does need your YouTube account's watch history to be active to work. You will know that this is the case if you can see the red bar at the bottom of thumbnails linking to videos you've already started to watch.
