CortexDJ
What it is
CortexDJ analyzes local music files and assembles DJ sets based on a selected folder, vibe and length. It detects Camelot key, energy, exact BPM and song structure, then aligns beatgrids to real kick drums. Its AI sequences tracks harmonically, shapes an energy curve and applies transitions such as filter sweeps, echo throws and bass swaps. Tracks whose beatgrids cannot be locked with confidence are excluded from auto-mixes and identified to the user. Live decks provide EQ, effects, loops, hot cues and pads, and users can take control while an AI mix is running. The Free plan is for home use and includes analysis, auto-mix, mashups, live decks, mix rendering and exports. Pro costs $7.45 a month and adds controller support, audio and HD video recording, live-streaming and priority email support. Lifetime costs $127, paid once. The software reads local audio files, but Spotify, Apple Music and TIDAL libraries are not supported. Desktop support includes 64-bit Windows 10/11 and a macOS Apple Silicon beta; the browser mixer is a separate beta and not the full app.

The verdict
CortexDJ focuses on automatic sets built from local files, with deck controls and export options. Check library compatibility and platform status before choosing it; recording and streaming require Pro.
Who it suits
CortexDJ suits home users who want to build mixes from local music files, as well as DJs who want live deck controls. Pro is relevant to users seeking controller support, recording or live-streaming.
