Any of these works, and you can use several at once:

• Telegram: free, on any phone. The simplest option: send or share a link, tap a playlist. Best if you don’t pay for an AI.
• Claude: free plan, one custom connector. Best if you want to chat about your library, like “make a playlist of my 120 BPM house”.
• iPhone Shortcut: free. Share from Spotify or YouTube and pick a playlist, with no chat.
• ChatGPT: needs a paid plan (Plus or higher) for custom connectors. Best if you already pay for ChatGPT.

ChatGPT keeps its own copy of DJ Sync’s tools from when you added it, so after DJ Sync gains new features it can still think DJ Sync “can only download”. On chatgpt.com, open Settings → Apps & Connectors → DJ Sync and click Refresh (or remove it and add it again), then start a new chat. More detail.

Either works. With Rekordbox closed, new tracks and playlist changes reach your library within seconds. With Rekordbox open, they show up straight away under rekordbox xml in the browser, and go into your Collection and playlists the moment you quit Rekordbox. Rekordbox locks its library while it runs, so DJ Sync waits rather than risk it.

Into Music › DJ Sync by default. You can pick another folder from the DJ Sync menu. Playlists DJ Sync creates live in a DJ Sync folder in your Rekordbox playlists.

DJ Sync backs up your library before every change it makes. The very first backup (v1.0.0) is your untouched library and is kept forever. To go back, open the DJ Sync menu, then Rekordbox library → Backups, and click Restore next to any version. A restore backs up your current library first, so you can undo it too. Keep Rekordbox closed while restoring.

Your request still goes through. It waits in the DJ Sync cloud, and your Mac picks it up as soon as it’s back online. Your assistant or the Telegram bot can tell you the status in the meantime. Browsing and searching your playlists works while your Mac is offline too, from the last copy your Mac shared.

Any Mac with macOS 14 Sonoma or later, Apple silicon or Intel. A Windows version is planned.

It’s free, and there’s no account, email or password. On first launch your Mac gets its own private identity with the DJ Sync cloud. To send it requests you need one of: Telegram (free), Claude (free plan, one custom connector), the iPhone Shortcuts app (free), or ChatGPT on a paid plan.

DJ Sync is free and isn’t registered with Apple’s paid developer program, so macOS asks you to confirm it once. The install guide shows exactly where to click. Updates install themselves without asking again.

Open the DJ Sync menu, go to Assistants, and click Rotate next to that link (or Disconnect). The old link stops working immediately. Paste the new one into ChatGPT or Claude, or put the new key in your iPhone Shortcut. For Telegram, send /stop in the chat or click Disconnect, then pair again.

Only what it needs: the links you ask for, playlist names and job results, and a copy of your library’s track titles, artists, albums, genres, BPM, keys and lengths so your assistant can browse it while your Mac is offline. Never file paths, never audio, never your name or email. Details are in the privacy policy.

Quit it from its menu and drag DJ Sync from Applications to the Bin. To remove everything else, delete the hidden .dj-sync folder in your home folder (it holds DJ Sync’s tools, settings and library backups, so keep the backups if you might want them) and ~/Library/LaunchAgents/com.triplejmusic.dj-sync.plist. Your music and your Rekordbox library stay as they are. The cloud deletes data for Macs that haven’t connected for 90 days.

DJ Sync is for your own prep. Only download music you have the right to use, respect the terms of the services you use, and buy what you play out. See the terms.
