FAQ

Is it really free?

3 free analyses per visitor, no account. Unlimited analysis is in GreenGo.

What is the Camelot code?

The DJ wheel notation for keys — neighboring codes (8A → 9A) mix harmonically.

What happens to my file?

Analyzed once, deleted immediately. Never stored, never added to the library.

How accurate is the detection?

Accurate enough for DJ harmonic mixing. Atonal or modulating tracks may vary.
