BPM · KEY · ENERGY — MEASURED, NOT GUESSED
Engineered setlists,
not shuffles.
Paste a Spotify playlist. We analyze the actual audio in your browser — tempo, key, energy — then sequence a set that warms up, peaks, and lands.

HOW IT WORKS
01
Analyze
Every track's preview is decoded in your browser. Essentia measures true BPM, key, and energy from the waveform — no stale metadata.
02
Match keys
Transitions follow the Camelot wheel. Adjacent keys mix clean; clashes are scored out of the sequence.
03
Shape the arc
The set builds like a real one: warm-up, climb, peak, cool-down. No random walks through your library.
Bedroom DJs
30 compatible tracks, ready to load into the deck.
Party hosts
Dinner-chill to dancefloor to wind-down, automatically.
Runners
Warm-up, high-BPM sprints, recovery cooldown.
Curators
Radio-grade transitions your listeners won't skip.
