What ships in the product

Premium desktop Auto-DJ: seed a track, build a set from your library, play it locally. Analysis and export support that loop—not the other way around.

implemented

6 modules

Create a set from any track
Pick a seed you love. dubgrep builds a timed journey from your own files—tempo, key, and energy shaped into a real set.
Auto-DJ in the app
Prep blends and mix points, then press Play. Tempo-aware crossfades keep the hour moving—no controller required.
Deep library analysis
BPM, Camelot/OpenKey, energy, groove, and structure—cached locally so search and set-building stay instant.
Search that thinks in music
Find the right seed fast: text, tempo, key, harmonic neighbours, energy, and groove filters on big crates.
Save, repeat, export
Keep favorite sets under My sets. Optional M3U or Rekordbox XML when you want to leave the app.
Your files stay yours
No accounts. No telemetry. Analysis and playback run on your machine. Optional tag write-back with backups.

principles

01
The hour is the product
Seed → set → Play should feel inevitable. Everything else supports that loop.
02
Deterministic, not black-box AI
Explainable tempo, key, and energy rules—same seed, same logic, offline.
03
Your crate, your machine
Built for people with real libraries—not streaming radio with a new skin.
