Focus groups lie. A/B tests are too late. Brand-lift studies take 6 weeks, cost $50K, and tell you nothing about why a message failed.
So we built Prophet — an open-source platform that simulates how your message spreads through 10,000 AI agents organized into the communities you actually care about.
💡 Think of it as a wind tunnel, but for campaigns instead of airplanes.
🔄 The Core Loop
| ⚙️ 1. Set up Message · communities · dials |
▶️ 2. Run 10K agents · real-time 3D graph |
⚡ 3. Intervene Pause · inject crisis · replay |
| 📊 4. Analyze Adoption curves · sentiment |
🔍 5. Drill in Read actual conversation threads |
⚖️ 6. Compare Clone · change variable · diff |
🧠 What's Under the Hood
| Component | Detail |
|---|---|
| Agent Architecture | 6-layer cognitive stack: perception → memory → emotion → cognition → decision → influence
|
| Network Model | Hybrid Watts-Strogatz + Barabási-Albert with validated clustering & modularity |
| Opinion Dynamics | Deffuant bounded-confidence model for endogenous polarization |
| Emergent Detectors | Viral cascade · Slow adoption · Polarization · Collapse · Echo chamber |
| Cost Control | 3-tier LLM inference — full 10K-agent run under $5 |
| Uncertainty | Monte Carlo sweep with P5 / P50 / P95 quantification |
🚀 Get Started
git clone https://github.com/showjihyun/Prophet
cd Prophet
npm install
# No API keys required to start
npm run dev
✅ Reproducibility Guarantee
Every claim in the README has per-step JSON you can audit.
Every equation traces back to a published paper.
Everything is reproducible. Runs on a laptop.
🤝 We're Looking for Contributors
Especially:
- 🐛 Bug reports

🔮 Prophet
The wind tunnel for marketing campaigns
Test your campaign on 10,000 AI agents before you spend a dollar on the launch.
🚀 Quick Start · ✨ Features · 🎯 Use Cases · 📊 Comparison · 📖 Docs · 🤝 Contributing
git clone https://github.com/showjihyun/prophet.git
cd prophet && docker compose up -d
open http://localhost:5173
That's it. 5 minutes from clone to your first simulation. No API keys required to start — Prophet runs fully locally on a laptop.
💡 Why Prophet?
Focus groups lie — 10 humans in a room cannot tell you how a message spreads through a community. A/B tests are too late — by the time you have data, you're already paying for the launch. Brand-lift studies take 6 weeks, cost $50K, and tell you nothing about why a message failed.
Every discipline that ships things at scale — aerospace, civil engineering, software — gets to simulate…
