Built for crates that live on disk

Not a streaming wrapper. Not a cloud SaaS. A premium desktop app that understands the music you already own — search, analyze, build sets, and export without leaving the box.

01

Performance is the product

Index, search, and analysis should feel instant on real libraries — not demos.

02

Explainable intelligence

BPM, key, energy, and structure you can trust enough to mix on — not black-box magic.

03

Desktop-first, local-only

A premium native app for crates that live on disk — waveforms, sets, and play in one place.

Deep library analysis

BPM, Camelot/OpenKey, energy, rhythm density, brightness, groove stability, and structural landmarks — cached for instant recall.

Search that thinks in music

Filter by text, tempo range, key, harmonic compatibility, energy, and groove. Virtualized lists that stay fast on big crates.

Waveforms & mix points

Full-track peaks, mix-in / mix-out cues, and session overrides you can drag on the waveform before you hit Play.

Auto-DJ that respects tempo

Build arcs, score edges, crossfade with tempo-aware blends. Beatmatch v1 via playback rate — honest about what it is (and isn’t).

Sets & export

Save sets, estimate duration, skip missing files, export M3U or Rekordbox XML with BPM/key/tempo cues.

Your files stay yours

Optional tag write-back for BPM & key with backups. Cache is local. Nothing leaves the machine.
