1Start playing the song in YouTube or Spotify, then click 🎸 GET CHORDS
2A browser dialog appears — select "Chrome Tab" (not Window or Screen)
3Click the tab that is playing the song, then click Share
4Let the song play through once. Looper builds the chord chart in real time. You only need to do this once per song — it caches for everyone.
💡 Once analyzed, chords load instantly next time — no need to repeat the capture for the same song.

1Start the YouTube video from the beginning. Click 🎸 GET CHORDS
2Browser dialog: choose Chrome Tab, select the YouTube tab, click Share
3Let the full song play. The chord chart builds automatically as audio comes in.
4Done. Chords are cached — the next person who opens that song gets them instantly, no capture needed.
