About
Spiral DJ is the preparation intelligence between your library and the booth. It is not DJ software and not a mixing app: it is a local-first DJ set preparation system that analyses your own music, takes the intention of the night as its input, routes the journey, checks the transitions, finds the weak points before the booth, exports the running order and remembers what actually happened.
Spiral DJ reads BPM, Camelot key, energy and waveform on your own machine, classifies genre from the audio itself, finds what fits next with the reason why, prepares HOLD / LIFT / RESET / SURPRISE alternatives for every point, and checks the whole set with evidence for every finding.
No cloud analysis, no uploads, works offline, full JSON backup. Free up to 500 tracks. Pro adds professional exports (Rekordbox XML, Traktor NML, M3U8, CSV), a printable booth sheet, Gig Log and Forgotten Gems. Made by DJs in Portugal.
