Deep Cuts
For listeners, DJs and producers

Deep Cuts: your music taste, decoded.

Drop in your music library exports (Spotify, Apple Music, rekordbox and more) and get an explorable map of what you love: your eras and moods, the DJ lanes hiding in your library, and the sound you'd make as a producer. Every chart opens the songs behind it.

Your files never leave your browser. Everything is analyzed on your device. Nothing is uploaded, stored or shared, and closing the tab clears it.

Your lanes on a BPM map, a Camelot key wheel, energy × tempo, a set planner that orders tracks by key and tempo, and forgotten gems.

How your inspiration playlist differs from your listening, your target tempo and mood, and a reference board of tracks to study.

About Deep Cuts

I'm Alina. I started DJing this fall and wanted to understand my own taste: what I actually save, how it's changed, and which songs would work in a set. Year-end recaps tell you what you played, but not why it all fits together. So I built the tool I wanted, then opened it up so anyone can run their own library through it.

Private by designYour files never leave your browser. There's no account, no server and no tracking. Close the tab and it's gone.
How it reads your musicGenres come from your music service, and tempo, key and mood come from Spotify's audio data. Every insight comes from fixed rules applied to your numbers, not AI guesses, and "How it works" in your report shows the math.
Built withClaude as a coding partner, plus a handful of open tools: Exportify, PapaParse, JSZip.
