| Product | AuraJam is an AI DJ that analyzes songs’ tempo and key, orders them into a set, and mixes them beatmatched at phrase turns. | CortexDJ analyzes local music files and builds beatmatched DJ sets from a selected folder, vibe and length. |
| Stem separation | It can separate vocals and drums from tracks, and the site says this runs on the user’s machine. | On-device AI stem separation splits bass, drums and vocals for mashups and cleaner swaps. |
| Track analysis | The product reads track key and tempo and identifies phrase turns to guide its mix decisions. | The app detects Camelot key, BPM, 1–10 energy and intro, drop and outro structure. |

In their own words
AuraJam
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.
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.
