Real feedback from DJs around the world using MasterDJ AI.
★★★★★
I used MasterDJ AI at my cousin's wedding and everyone thought I hired a professional DJ. The automix feature saved me — I just loaded my playlist and it handled all the transitions perfectly. Best $14.99 I ever spent.

I've tried djay Pro and Virtual DJ but they're expensive and heavy. MasterDJ AI does 90% of what I need for free, and Pro is a one-time payment. The rainbow waveforms look amazing on a big screen behind the booth.

Perfect for mobile gigs. I carry it on a USB stick, open it on any computer with Chrome, and I'm ready to go. No installation, no license issues. The BPM sync works great for keeping the energy up.

The live song request feature changed everything. At my last house party, everyone was scanning the QR code and requesting songs from their phones. It made me look like a real DJ. The app supports Hindi which is a nice touch!

Increíble que todo funcione en el navegador sin instalar nada. Lo uso en cada fiesta familiar. The karaoke mode is a hit — my friends love singing along. And the song request QR code? Genius.
