A songwriter's workspace with an AI co-writer for lyrics, rhymes and chords
Over 500,000 rhymes and trigger words filtered by genre, ranking singable perfect, near and phrase rhymes first and letting you filter by syllable count.
Offers phrase ideas for a title or line and suggests what could come next without writing the song for you; kept lines remain yours and are not used for training.
Explore rich, singable chords and full progressions, hear them in context, and pick up music theory along the way.
Short exercises sharpen hooks, rhyme, melody, structure and editing, while songwriting guides sit beside your songs inside the app.
Rhyme dictionary, lyric editor and AI songwriting partner in one app
Find rhymes and near-rhymes quickly in English, Spanish, French and Norwegian, with synonyms served from the same screen.
Check how many syllables a line carries so verses fit the beat or melody instead of being trimmed by ear later.
Ask for help when a verse stalls and get word, line and direction ideas you can rewrite into your own voice.
Write against real loops from producers highlighted in the app so you can test phrasing against an actual groove.
