Why Producers Choose BeatKey
DJs who need the Camelot code

Five tools, one suite
BeatKey is one of five free tools: BPM+Key Detector, Chord Finder, BPM Delay Calculator, Scale Finder, and Note Frequency Calculator. All integrated, all free, all browser-based.
What Is OpenMusic AI?
OpenMusic AI is a browser-based audio analysis tool that uses AI to detect BPM, musical key, and Camelot codes. It also provides extra metrics like energy, danceability, and "happiness" scores derived from the audio content.
Those extra metrics can be interesting, but most DJs and producers just need the key and BPM. BeatKey focuses on exactly that: clean key detection with Camelot code output, precise BPM, and a full suite of companion tools for the next steps in your workflow (chord detection, delay times, scale lookup, note frequencies).
BeatKey is completely free with no account requirement and no ads. The entire BeatKey Tools suite (five tools) is free forever. No energy scores, no AI labels, just the data you actually use.

BeatKey shows the Camelot code alongside every key detection result, plus links to the interactive Camelot Wheel.
