Melody Generator
Generate melodies by genre, mode and complexity, then shape them note by note on the staff. Regenerate a bar without touching the rest.
Generate a melodyThe musical inspirationyou’re looking for
Songwriting AI for musicians who want granular control over melody, chords, and lyrics as separate, editable parts on a real score.
Why Choorus
Not another audio generator
Choorus generates a song you can actually edit.
Granular control
Build a masterpiece in parts
Audio generators hand you a finished track that you might not be able to musically recreate. Choorus writes melody, chords and lyrics as separate parts on a real score, so every songwriting decision stays in your hands.
- Highlight a word, a measure, or a single chord and re-generate only that
- Edit any note, chord or syllable by hand, with version history
- Export MIDI or audio of each part to any DAW
Music theory on a dial
Chords at the level you want
Choose how adventurous the chords should be and Choorus fits a progression to your melody, from diatonic triads to secondary dominants, borrowed chords, and extensions.
- Three levels: Easy, Normal and Complex
- Every suggestion is fitted to the melody you already have
- Highlight only the chords you want to re-generate

Made for people who finish songs
Our models understand song structure and music theory, so your time goes into ideas rather than scaffolding.
Every melody, chord progression and lyric you generate is yours. No royalties, no licensing fees.
We started Choorus because, as musicians, we were fascinated by the magic behind melodies. Sign up below to follow what we learn along the way and to hear about new features first.
FREQUENTLY ASKED QUESTIONS
How is Choorus different from AI music generators?
Most AI music tools generate one finished audio track that you cannot take apart. Choorus generates the parts instead: melody, chords and lyrics as editable notation. You can change a bar, a chord or a word, hear it sung back, and export MIDI to your DAW or hand the score to real musicians.
Can I edit what Choorus generates?
Yes. Everything lands on an editable score. Change notes, chords and lyrics by hand, or highlight a selection and regenerate just that part while the rest of the section stays as it is.
What do the chord complexity levels mean?
Easy keeps to diatonic triads. Normal adds sevenths, suspensions and inversions. Complex brings in secondary dominants, borrowed chords and extensions. Whatever the level, the progression is fitted to the melody you already have.
Can I hear my lyrics sung?
Yes. Every time your lyrics or melody change, the vocal is re-rendered with a commercially licensed AI voice, so you can hear the idea out loud and download it as MP3 or WAV.
Do I need to read music?
No. The score helps if you do, but playback, the sung vocal and MIDI export mean you can work entirely by ear.
How do we ensure originality?
We've built a rigorous process that evaluates each generated result for originality and creativity. Everything you generate is yours, with no royalties or licensing fees.
