How AI Writes and Sings a Song
Song AI works in four stages: words, melody, band and voice. Each stage learns patterns from music, then follows your lyrics and style to build a finished track.
By Nora Ellis · Updated

Song AI questions
Can I make a free AI song?
Yes. You can start free in your browser and get two complete sung takes from every idea. All the songs AI writes for you are yours to keep and compare.
How does AI fit words to a melody?
It splits each line into syllables and places stressed syllables on strong beats, then shapes the tune around them. Short, even lines sing most clearly.
Can I choose a male or female voice?
Yes. Name the voice in Style, such as warm male baritone or airy female vocal.
Why do two takes sound different?
Each take explores a fresh melody and arrangement from the same input, so you can pick the one that fits best.
Does the song follow my sections?
Yes. [Verse], [Chorus] and [Bridge] tags set the order, and the chorus returns where you place it.
Can I get the vocal on its own?
Yes. The Stem Splitter separates the voice from the band.
