In their own words
CortexDJ
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.
Offtrack
Offtrack is an AI DJ app that shortens songs and mixes them with transitions. Smart Mix trims tracks, queues songs based on how they fit together, and creates transitions; Highlight Mode focuses playback on song highlights. On iOS, users can adjust highlight lengths, edit the queue, save mixes as playlists, sort tracks by BPM or energy, and filter explicit songs. The iOS app works with Spotify Premium, Apple Music, TIDAL, SoundCloud Free, a local music library, and CarPlay, though catalogue availability varies: Spotify Premium and Apple Music are partial, TIDAL is full, and SoundCloud Go+ tracks are unavailable. Android supports Spotify Premium and SoundCloud Free, but its FAQ lists offline playback, EQ, saved transition points, and saved mix order as not yet available. Offtrack can recommend tracks matching a listener’s taste and add them to a mix. The Free plan includes unlimited Smart Mix and Smart Queue, limited Highlight Mode plays, and discovery of up to 300% new songs. Pro is $4.99 a month and includes unlimited Highlight Mode plays.
