The syllable counter runs on the line while you write. Rhymes highlight in the verse. Open rhyme groups, end rhymes, or Suggest Rhymes when you need a word that fits. Flow See the stress, the punch, the rhyme density, and how tight the bar sits on the grid. Suggest next lines when you want another bar in the same pocket. Those tools use your own OpenAI or Gemini key, and the key stays on your phone. Beat, Nouns, and Export Keep the BPM and the scale with the note. Add a beat and a vocal. Pull nouns into the line. Export the finished rap lyrics to PDF or Word when you are ready for the studio. iPhone Duo Open the fold and the journal sits on one side while the page sits on the other.
