ChordCreate

The whole interface is a text field and a Generate button. You describe key, genre, mood and tempo in ordinary words, and the AI chord progression generator builds a progression aimed at that brief. A fast and accurate toggle trades waiting time for how closely the result follows a detailed prompt. The output is a starting point, not a finished arrangement, and rewriting one line of the prompt usually moves it closer.

Every result lands in a chord sequencer where chords sit as blocks on a timeline. You can drag them into a new order, remove the weak ones, add chords of your own and zoom in to edit individual notes. Sequence history keeps earlier versions, so an experiment you regret is one click from being undone. This is the part that turns a generated idea into something you'd actually use.

Chords play back in the browser on several instruments, and the loop runs at whatever BPM and time signature you set. Hearing a progression at 70 and then at 128 BPM changes how it reads, which is why the tempo control matters more than it sounds. You can sit on a four bar loop until the movement either works or clearly doesn't.

Export is the paid feature most people come for. MIDI gives you editable notes for any DAW, and WAV gives you audio when you just need to hear the idea somewhere else. Both sit behind the $5.99 monthly plan, so budget for it if the file matters to your workflow.

The humanise switch loosens the timing and velocity so chords stop sounding mechanically quantised. The full instrument list also unlocks on the paid plan, which matters if you want a Rhodes or a guitar-ish part rather than a plain piano. These are small controls with a large effect on whether a sketch sounds like music.

Three tools sit outside the generator and need no account: an interactive circle of fifths, a labelled virtual piano and a chord finder that shows notes, playback and inversions for any chord. The chord finder is the useful one when a generated symbol like Fmaj7#11 leaves you unsure what to play. They also work as a quick reference while you write, which makes the site a reasonable browser-based music tool beyond the prompt box.
