What Is Algoriddim djay?
djay by Algoriddim is a popular mobile and desktop DJ app available on iPhone, iPad, Mac, Android, and Windows. It uses AI-powered features including Neural Mix (real-time stem separation for drums, melody, and vocals), streaming integration (Spotify, Tidal, SoundCloud), and Automix for hands-free DJ sets.
djay Pro AI is the paid tier at $9.99/month that unlocks advanced features including AI key detection. The free version (djay for iPhone) has limited analysis capabilities. Key detection is shown as a musical key name (like "Am" or "G major") but Camelot wheel notation codes are not displayed directly in the app.
djay is designed as a full performance tool for DJs who mix live. If you need to quickly check the BPM and key of a track you downloaded, a sample, or an unreleased promo, opening the full djay app and importing the track takes significantly longer than uploading directly to BeatKey.

When to Use BeatKey Instead of djay
Quick check before a set
You downloaded a promo or track and want to know the key and BPM before your gig tonight. Opening BeatKey in a browser tab is faster than importing into djay and waiting for AI analysis.
Unreleased and promo tracks
djay connects to streaming services but cannot analyze audio files it does not recognize. BeatKey accepts any audio file: MP3, WAV, FLAC, AAC, OGG. Perfect for DJ promos, white labels, and edits.
You need Camelot codes
djay Pro AI shows the key name but not the Camelot notation used in DJ libraries. BeatKey shows both, and the result links directly to the Interactive Camelot Wheel with compatible keys highlighted.
No subscription budget
djay Pro AI is $9.99/month. If you only need BPM and key detection (not full live mixing features), BeatKey is the free alternative with no subscription, no trial expiry, and no account required.
When djay is Still the Better Choice
BeatKey is an analysis tool, not a full DJ app. djay Pro AI is the right choice when you need:
For bulk library tagging on desktop, also consider KeyFinder (free, open-source, Mac/Windows) or OpenKeyScan (free, AI-powered, rekordbox/Traktor/VirtualDJ integration).
