AI Scéniste — AI for story simulation
Patented story simulation AI for script novel & game writing
AI Scéniste is an AI scriptwriting tool powered by our patented "story simulation" engine. Define character motivations, personalities, and relationships — the engine simulates their autonomous interactions and converts events into a script. This keeps consistency and plot coherence intact even at 100K+ characters. Used by Japan's leading scenario studio: creation time dropped 78% (8h→1.8h). Works for scripts, novels, and game scenarios. From ~$3/mo. 1-week free trial.
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! 🙏
