Lyrics that keep time.
Synced lyrics light up line by line as the song plays.
Kaset
Two sides.
One Mac app.
YouTube Music on Side A. YouTube on Side B.
A native macOS app for both. Free and open source.
Downloaded by hand? Clear quarantine first
xattr -cr /Applications/Kaset.app
Homebrew
brew install sozercan/repo/kaset
Requires macOS 15.4 or later. Kaset isn't signed with an Apple Developer ID yet. Homebrew clears the quarantine flag for you.
Flip the tape above. The same switch sits at the bottom of Kaset's sidebar.
Side A
YouTube Music, with everything a browser tab leaves out.
Your library, your mixes, your Premium playback. In a real window, with real controls.
A real equalizer.
Six bands with presets, applied to the audio output itself.
Queue and smart shuffle.
Reorder what plays next, or let Kaset blend in suggestions based on what's playing.
Side B
YouTube, with native controls and none of the clutter.
Flip the switch and the same sidebar becomes subscriptions, Shorts, Watch Later, and history.
Native player bar.
Captions, quality, picture in picture, and AirPlay from Kaset's own Liquid Glass bar.
Extensions on both sides.
Load WebKit extensions like uBlock Origin Lite and SponsorBlock. Nothing is bundled. You choose.
Links land here.
Hand a youtube.com or youtu.be link to Kaset, from Shortcuts or open -a Kaset, and it opens on Side B.
Built for the Mac.
Not wrapped for it.
Swift, SwiftUI, Liquid Glass, and 18 languages. Kaset shows up everywhere a Mac app should.
Now Playing, everywhere.
Control Center, media keys, the Dock menu, and a mini player. Keeps playing when the window closes.
Keyboard first.
Full control from the keys. Standard macOS shortcuts are left alone.
Apple Intelligence.
On macOS 26, ask for music in plain words and get lyrics explained, on device.
Scriptable.
AppleScript for Raycast, Alfred, and Shortcuts.
