What it is

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.
