Peekabop shows the lyrics of whatever's playing right under your MacBook's camera, lighting up word by word in time. Spotify, Apple Music, or YouTube and other sites in Safari, Chrome, Arc or Firefox. Pick the notch, a floating pill, subtitles or full screen, and one of 16 effects. On macOS 26 it even shifts the lyrics to match a music video's edit. No account, no analytics. €9.99 once, 7 days free.
