Fall in love with the music.
Own the language.
PhonetiSync injects sub-second phonetic subtitle guides and translation layers directly onto YouTube. Sing along instantly to C-Pop, J-Pop, and anime themes, then watch the scaffolding fade as you master the lyrics.
The 3 Steps to Fluency
Sing it first
Immediate vocalization builds neurological muscle memory. Phonetic approximate spellings bypass Pinyin/Romaji friction, getting you singing in key in seconds.
Understand it next
Tap any line in the extension sidebar to fetch natural context-aware English translations on-demand. Bridge the gap between acoustic sound waves and meaning.
Own it eventually
Track your play logs. As your familiarity grows, the phonetic guidance track fades away progressively, leaving you with original native character scripts.
