CortexDJ vs MIXX Intelligence

CortexDJ analyzes local music files and builds beatmatched DJ sets from a chosen folder, vibe and length. It identifies Camelot key, energy, BPM and song structure, then adjusts beatgrids to real kick drums. Its automated mixing orders tracks harmonically, shapes an energy curve and applies transitions including filter sweeps, echo throws and bass swaps. Tracks whose beatgrids cannot be locked confidently are excluded from auto-mixes and flagged. Live decks provide EQ, effects, loops, hot cues and pads, and users can take control during an AI mix. All tiers export rekordbox XML with beatgrids, hot cues and crates, plus Serato-readable playlists and crate files; Serato hot cues are not included. The Free plan is for home use and includes analysis, auto-mixing, mashups, rendering and exports. Pro is $7.45 a month and adds controller support, recording, live-streaming and priority email support. Lifetime is $127, paid once. Desktop support is 64-bit Windows 10/11 and a macOS Apple Silicon beta; the browser mixer is a separate beta, not the full app.

MIXX Intelligence is a DJ workstation for macOS that analyzes tracks and musical context to support set building and transitions. It evaluates BPM, Camelot key, energy, and beatgrid, as well as phrase, vocals, riddims, and transition intent. Transition choices include Blend, Cut, Drop on One, Scratch In, and Echo Out. Automix can run while leaving the DJ able to take over at any time. The controller layer supports Pioneer DJ, AlphaTheta, and Hercules hardware, with eight controller bindings listed. Documentation describes importing beatgrids from Serato or Rekordbox and protecting hand-set grids from being overwritten. The free Prepare plan costs nothing and includes crate import and track analysis. DJ costs $7.99 a month; Pro costs $9.99 a month and adds stems and mashup features; Radio costs $19.99 a month and includes scheduled shows, AI DJ personas, voice and drops, and station streaming. The maker says analysis and mixing take place locally, with audio not uploaded to its servers. The app requires macOS on Apple Silicon or Intel.
