When your core feature is a daily audio briefing, voice quality IS the product. Here's how I thought about it.
Why OpenAI TTS
I tested several providers. OpenAI won for English: natural pacing, good intonation, and smooth transitions between topics in a briefing. A typical 5-7 minute Signal costs ~$0.03 0.05 to generate. At a few hundred users, that's fine. At 50K users (I can dream), that math changes fast.
The tradeoff: OpenAI is limited for other languages, and there are only a handful of voice options. No customization of tone or personality.
Read-it-later never really worked. We save now, but later never comes. Content stays unread.
So I built listen-it-later: NoiseCut.
Save articles, tweets, notes. It turns your pile into 5–7 min audio briefings, narrated like a real podcast host (OpenAI TTS). Delivered daily, weekly, or on demand.
Listen while commuting, cooking, walking. Save now, actually consume later—no screen needed.
