SubLib

Follow too many channels? SubLib turns your YouTube subscriptions into folders like Cooking, Tech or Kids. Each folder gets its own feed of new videos, so nothing gets buried again.

SubLib library: 13 new videos tonight, a play-this-now pick and your folders

// what it does

Folders for your YouTube subscriptions.

Folders for your channels

Group channels into folders like Cooking, Tech or Kids, with your own color or cover photo. A channel can be in more than one folder.

Suggest folders

Sort your channels in one tap, using the topics YouTube already gave them.

Every new video, one library

Each folder gets its own feed of new videos, plus one library of everything new with a “play this now” pick at the top.

Watched, saved, filtered

Videos mark themselves watched when you open them, with one-tap undo. Save for later, hide Shorts, or show only 10+ minute videos.

Find dead channels

See subscriptions that haven’t uploaded, or that you haven’t watched, in 6 months.

Search, reorder, widget

Fast search across all your channels and videos, drag to reorder folders, a home screen widget, and light and dark themes.
