Questions

Is the key finder free?

Free. After your first try we ask for your email once, then you can use it as much as you like.

How accurate is it?

Very accurate for most songs. If a song changes key or tempo, it shows the main one and other likely keys.

What is a relative key?

Every major key has a minor key with the same notes, like C major and A minor. Songs in relative keys sound good together.

Is my song uploaded?

No. Your audio never leaves your device: everything runs inside your web browser.

Can I find the BPM of a beat for rapping?

Yes. Drop the beat in and you get the BPM in seconds.
