Hey Product Hunt! 👋 I'm the creator of AI Scéniste. **The problem:** I spent 10 years in the Japanese scriptwriting industry. The biggest bottleneck wasn't creativity — it was consistency. Scripts over 50 pages inevitably had character contradictions, forgotten plot threads, and timeline errors. AI tools like ChatGPT helped with short scenes, but collapsed on anything novel-length. **What we built:** AI Scéniste uses a fundamentally different approach. Instead of generating text sequentially, we patented a "story simulation" engine. You define characters with motivations, personalities, and relationships. The AI simulates their interactions autonomously, and we record what happens. Think of it as running a miniature world, not writing a document. **Results:** - 78% time reduction in professional testing (8hr → 1.8hr for outline creation) - Works for scripts, novels, and game scenarios - Maintains consistency across 100K+ character works - Starting at ¥480/month (~$3) with 1-week free trial **Why now:** 2026 is the year AI moves from "generate text" to "simulate worlds." We're building for that future. I'd love your feedback — especially from writers, game designers, and anyone who's wrestled with long-form narrative consistency. What's your biggest pain point when writing long stories? Ask me anything! 🙏
