theIDOL

theIDOL is a web app for learning Korean through K-pop songs. Open a song and every line is shown in two layers, a word-by-word gloss and a natural translation, both highlighted in sync with the music.

Features: • 416 K-pop songs broken down line by line; new releases are added shortly after they drop • Romanization written the way the line is actually sung, not textbook spelling, from its own pronunciation engine • Tap a word to see what it means in that line • Fill-in-the-missing-word exercises built from the lines you study • A vocabulary notebook with spaced repetition • A Hangul alphabet course • Dance practice split into 8-counts, with slow-motion and mirror modes • Song pages in English, Spanish, Portuguese, Japanese, Thai and Traditional Chinese

Song breakdowns and the catalog are free, and the first verse of every song needs no sign-up.
