Hey Product Hunt! 👋 I'm Yusuke, founder of opus LLC. For 20 years in digital media, I watched the same problem repeat: a 30-minute interview takes 3 weeks and $500+ to become a published article. The bottleneck was never the conversation—it was the production pipeline. Transcription, structuring, writing, editing... all manual, all expensive. So I built sonata. 🎙️ Upload interview audio → get a draft in ~1 hour 🎯 AI learns your brand's tone from past articles 👥 Patent-pending speaker separation (JP Patent App #2025-146411) 📊 Team editing, media management, and analytics in one platform Real results from early users: • Production cost: $4,100/article → ~$27/article (92% reduction) • Production time: 8+ hours → ~1 hour (87% faster) We built this primarily for the Japanese market, but English is fully supported.
