AuraJam vs SetPrep

AuraJam is a browser-based AI DJ that analyzes songs’ tempo, key, and phrase turns, then arranges them into a beatmatched set. Tracks can be added by dropping in a folder or pasting a link. You can change its choices by removing a record, moving a blend, or adjusting where a transition cuts. It can separate vocals and drums, and align footage to the music’s beat grid. For parties, guests can scan a QR code to request records from their phones, and the AI DJ incorporates requests into the set. AuraJam runs in a browser on the user’s GPU, needs no installation, and can be tried without an account. Its Free plan costs nothing and permits five exports a day with a small mark; on-device tools are unmetered. Pro costs $9.99 a month and includes unlimited exports without a mark and 500 monthly credits for AI generation. The site says separation, transcription, tempo and key analysis, and exports run on the user’s machine; AI video generation is an exception identified before use. The AI explains its mechanical decisions, but users judge whether tracks sound good together.

SetPrep is a desktop app that plans DJ sets from an existing music library. Choose a mixing style and it returns an ordered set, giving each track an energy-arc role, a transition note, and an explanation of its selection. It reads libraries from Rekordbox, Serato, or Traktor, and can also work from a folder of audio files. Ten built-in mixing-style templates draw on analysis of real artist sets. SetPrep can write colour codes, transition notes, and star ratings back to supported DJ libraries. Other library tools include de-duplication, locating missing files, filename repair, and finding forgotten tracks. The beta is available on Mac with Apple Silicon or Intel and Windows with x64 or ARM64, but downloads are invite-gated. The free plan costs nothing and allows three generated mixes per calendar month. Pro Monthly costs £5.99 a month; Pro Annual costs £59.99 a year. Hot cues, loops, memory cues, and structural cues are described as coming soon.
