I use newpipe, freetube instead of youtube.
It has everything but the discoverability that youtube provided.
I would atleast like a way to find new channels based on the channels I subscribe, if not new videos based on watched videos.
Need suggestions.
Not exactly what you want, but below each video in freetube, there’s an ‘up next’ playlist that afaik are still recommended. You can use it to find similar content.
