Co-Pilot

Connect BPMDex to Claude or ChatGPT and get an assistant that already knows your library. Ask for a 90-minute techno set at 128–132 BPM in 8A, nothing played in the last month — and it builds the playlist directly in BPMDex. With Multi-Source Playlists, it can pull from your library and Spotify or SoundCloud in the same request.

How It Works

From collection to crate in four steps

1
Connect your library
Import tracks via the web interface or directly through the REST API. Drag-and-drop uploads support MP3, WAV, FLAC, AIFF, and other common DJ formats.
2
Analyze & enrich
bpmdex automatically detects BPM and musical key for each track. Supplement with manual tags — genre, energy, mood, custom labels — to build a metadata-rich catalog.
3
Search & discover
Use the smart search to query across any combination of attributes. Save searches as dynamic crates that update automatically as new music is added.
4
Play & integrate
Access your library from any browser or the mobile app. Use the API to push data to Rekordbox, Serato, or any custom workflow. Your library travels with you.

Reviews

Built for every kind of music obsessive

What people across the music and tech world are saying about BPMDex.

★★★★★
“I spent years losing tracks across Beatport bookmarks, screenshots, and random notes. BPMDex became the central hub I always wished existed — less time searching, more time mixing.”
🎵
DJ
★★★★★
“Entity resolution, metadata normalization, graph relationships at scale — it’s exactly the kind of data problem that gets engineers genuinely excited. Think Spotify’s discovery plus IMDb’s data structure.”
💻
Software Engineer
★★★★★
“I discover one great track and BPMDex helps me find the next hundred. It’s like an interactive map of electronic music — artists, labels, and genres all connected in one place.”
🎵
Music Fan
★★★★★
“Most music platforms focus on streaming. BPMDex focuses on intelligence. If you love data, knowledge graphs, and search architecture, this is the platform you’ve been waiting for.”
📊
Technology Enthusiast
★★★★★
“Working on a platform like this gave me real hands-on experience with cloud architecture, databases, AI, and product design. What started as a passion project is becoming a real company.”
🏫

💼
Business Owner
★★★★★
“The opportunity isn’t just a music website — it’s the canonical data layer powering the next generation of music discovery, analytics, and industry applications. The data moat and network effects are real.”
