How Chord Draft feels it out

You bring the feeling. Chord Draft listens for the pulse in what you wrote, then checks the music theory hard enough that the loop still stands up when the feeling hits.

What the AI catches

It reads messy feeling words, lyric scraps, and half-finished thoughts without asking you to talk like a textbook.
It compares more than one musically valid direction when your idea could break in a few different beautiful ways.
It says what happened in plain language so the result does not feel like a black box with attitude.

What the rules refuse to let slide

They score the options for fit, clarity, playability, and whether the loop actually lands instead of just looking smart.
They audit Roman numerals, harmonic pull, tension and release, and voice-leading so the progression moves like it means something.
They reject weak explanation states, because “trust me bro” is not enough once the music is on the table.

What you actually see

You describe the feeling, lyric, or direction in your own words.
Chord Draft tests multiple harmony directions instead of pretending the first guess was destiny.
The chosen progression gets checked for theory, playability, and whether the explanation still makes sense.
Jam shows why that loop won, what it was chasing, and what other paths almost made it.

How to be specific when you want to steer

Exact chords: Use these exact chords: Am7 Fmaj7 C G
Exact progression: Keep A E F#m D exactly
Key and scale: 4 chords in A minor
Feel and style: Dreamy worship in D major
Continuation: I already have this verse: Am F C G. Give me a chorus next.
