This serves as a foundational tool for building chat experiences with persistent context.\n\n## Core Components\n\n1. **Chat Input**\n - Accepts user messages\n - Configures conversation storage\n - Tracks session identity\n\n2. **Chat Memory**\n - Stores and retrieves up to 100 previous messages\n - Maintains conversation context\n - Tracks separate chat sessions\n - Preserves sender information and message order\n\n3. **Prompt**\n - Creates dynamic prompt templates\n - Integrates memory into conversation flow\n\n4. **OpenAI**\n - Processes user input with context\n - Accesses conversation history\n - Includes options for model configuration and API key setup\n\n5. **Chat Output**\n - Displays formatted responses\n - Maintains conversation flow\n - Syncs with memory storage\n\n## Memory Features\n\n- Stores message history\n- Plans conversation trajectory\n- Differentiates between chat sessions\n- Preserves sender and message metadata\n\n## Quick Start\n\n1. **Initialize** with a clear session ID\n2. **Enter** message in Chat Input\n3. **AI Processes** with context from memory\n4. **Response** appears in Chat Output\n5. Context remains available for follow-ups\n\nThis robust system demonstrates thorough memory integration with minimal complexity. 🧠💬\n", | |
