Narration Room is a native Mac app, not just a text-to-speech box. It turns source text into editable multi-voice scripts, then lets creators cast voices, adjust delivery, preview on a visual timeline, and export polished audio. Standouts: source-grounded AI modes, 40+ on-device voices, PDF/Word/Markdown import, dictation mode; offline and local.
