YouTube, minus whatever you don't want.
Most focus extensions hide everything or nothing. Zena gives every distraction its own switch homepage recommendations, the sidebar, Shorts, comments, autoplay, so the feed you get is the one you chose.
One switch per distraction
Every hide-rule works on its own, so nothing you didn't ask for disappears. Keep the homepage clean but leave comments alone. Kill the sidebar but keep Shorts. It's your feed to edit, one toggle at a time.
Homepage recommendations
Hide the suggested-video feed on youtube.com. On by default.
Sidebar recommendations
Hide "Up next" suggestions beside a playing video. On by default.
End-screen suggestions
Remove the suggestion cards that cover a video in its last seconds.
Shorts
Hide Shorts shelves and the Shorts entry in the side nav.
Comments & live chat
Hide the comment section or the live chat panel on streams.
Explore, Trending & Autoplay
Tidy the left-hand guide and turn off YouTube's autoplay switch.
