Description

What This Does

Paste a YouTube link or drop in an audio file, and get a full musical breakdown — then play it back with the current chord highlighted in sync, like Chordify.

  • Chord Progression — every chord change, timestamped, on a bar chart
  • Tempo & Meter — precise BPM, half/double-time reading, and the 3/4-vs-4/4 feel
  • Key — with a confidence score and the closest alternative reading
  • Structure & Energy — the song's sections mapped out, with its energy arc drawn over time
  • Character — tonal brightness and how dynamic or compressed the mix is
  • Play-Along — hit play and watch the chords light up in time

Works with any public YouTube video — regular, Shorts, YouTube Music, youtu.be — or an MP3/M4A/WAV/FLAC file. Analysis takes about 15 seconds (a little longer the very first time). The line under the box says whether the analyzer is online and whether YouTube is currently letting it download; when YouTube blocks it, dropping the audio file in always works.
