A song lyric maker that hands over a finished lyric leaves you with words that read fine and sing badly, because nothing held them to a shape. This one builds the song with you instead: it sets the section order, the syllable grid and the rhyme scheme first, you approve that frame, and only then does it write, one section at a time, checking each line against the grid you agreed. It writes original lyrics only and never reproduces a line from an existing song.
Paste the prompt into a new chat, a Claude Project or a custom GPT, then say what the song is about, the genre, and the syllable count of a melody line if you have one. It works in stages and stops after each: the frame with a job per section, a rhyme bank per sound, the chorus, verse one on the grid, verse two on the identical grid plus the bridge, then a final pass with a prosody check and the three weakest lines. Every line carries its syllable count and its rhyme letter.
