  "canonical_description": "Songwriter Studio is a native iOS lyrics editor for iPhone and iPad, built for serious songwriters. It detects rhymes live as you type (perfect, near, and slant), can show per-line syllable counts, and anchors chord symbols to the words beneath them. Lyrics stay on the writer's device, synced through their personal iCloud account — never stored on Songwriter Studio's servers. The core editor is free with no ads and no account, and includes real-time co-writing on one shared song at a time; an optional Pro subscription adds songwriting analysis, unlimited collaboration, and MIDI and ChordPro export. It is made by Zaibatsu Heavy Industries Ltd.",
