+## 💡 The Idea
+
+Instead of asking **one** AI a question, ask a **team** of AIs.
+
+```
+You: "How should we architect our new microservice?"

+
+Models see each other's responses, debate, agree, disagree, and build upon ideas. You get richer, more diverse insights—then export everything as clean markdown.

+
+## ✨ Features
+
+| Feature | Description |
+|---------|-------------|
+| 🔀 **Open Mode** | Ask all models in parallel—get diverse initial takes |
+| 💬 **Discuss Mode** | Sequential rounds where models respond to each other |
+| 🎯 **@Mentions** | Direct questions to specific models: `@claude explain more` |
+| 🤝 **Consensus** | Auto-generated summary of agreements & disagreements |
+| 📁 **Projects** | Organize discussions by topic with persistent context |
+| 📤 **Export** | Beautiful markdown documents of entire discussions |
