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.

Hey Product Hunt, I'm Stefan, maker of Narration Room. I build Narration Room because I wanted an app that did exactly what I would do manually using several different tools: come up with the source material, transform it into something that can be spoken, then use AI to create the audio for it. Narration Room unifies that same workflow into one app. Import your text files, paste an article or email, or use dictation. Then turn your source material into an editable script, select speakers and voices, change emphasis, pitch, add and breaks. Preview the final result and export. For this launch the focus is on-device: no account, no subscription; everything runs locally on your Mac. Built for creators, educators, authors, podcasters, and anyone who wants to turn what they read into what they can hear. I'd love feedback on the workflow, audio quality, the AI, and what kinds of templates or export options you'd want next.
