Routing\n\n#### This n8n workflow empowers your AI agent with **long-term memory** and a **dynamic tools router**, enabling it to provide intelligent, context-aware responses while seamlessly managing tasks across multiple tools. By combining memory persistence and modular tool routing, this solution enhances the capabilities of your AI agent, making it smarter, more efficient, and highly adaptable.\n\n## 🚀 How It Works\n\n#### 🧠 Long-Term Memory Management\n- The AI agent can **save** and **retrieve memories** using Google Docs as a storage system.\n- Persistent memory allows the agent to recall past interactions, user preferences, and contextual details for personalized responses.\n\n#### 🛠️ Tools Router for Dynamic Task Management\n- A **tools router** directs tasks to the appropriate tools based on the AI agent's instructions.\n- Supported tools include:\n - **Save Memories**: Store important data for future reference.\n - **Retrieve Memories**: Access stored information when needed.\n - **Send Notifications via Gmail or Telegram**: Share insights or updates with stakeholders.\n\n#### 🤖 AI-Powered Contextual Understanding\n- The workflow integrates an OpenAI GPT-based model to process user inputs intelligently.\n- The AI agent uses a **window buffer memory** for short-term context and leverages long-term memory when necessary.\n\n#### 📤 Multi-Channel Notifications\n- Automatically send memory summaries or workflow updates via Gmail or Telegram for enhanced communication.\n\n---\n\n## 🔧 Setup Steps\n\n#### 🔑 Configure API Credentials\nSet up API connections for:\n- **OpenAI** (for AI processing).\n- **Google Docs** (for long-term memory storage).\n- **Gmail/Telegram** (for notifications).\n\n#### ⚙️ Customize Workflow Parameters\n- Adjust the AI agent's system message to align with your specific use case or tone.\n- Define routing rules in the tools router to suit your workflow needs.\n\n#### 🧪 Test & Deploy\n- Test the workflow by interacting with the AI agent and verifying:\n - Accurate memory saving/retrieval.\n - Correct task routing via the tools router.\n - Seamless notification delivery.\n" }, "typeVersion": 1 } ], "active": false, "pinData": {}, "settings": { "timezone": "America/Vancouver", "callerPolicy": "workflowsFromSameOwner", "executionOrder": "v1" }, "versionId": "5d92d73f-0341-4ab1-937e-6be387f6ea52", "connections": { "🧠Save Memories": { "ai_tool": [ [ { "node": "🧠 AI Agent w/Long Term Memory", "type": "ai_tool", "index": 0 } ] ] }, "Memory Tool Router": { "main": [ [ { "node": "Save Long Term Memories", "type": "main", "index": 0 } ], [ { "node": "Retrieve Long Term Memories", "type": "main", "index": 0 } ], [ { "node": "Retrieve Long Term Memories2", "type": "main", "index": 0 } ], [ { "node": "Retrieve Long Term Memories3", "type": "main", "index": 0 } ] ] }, "OpenAI Chat Model2": { "ai_languageModel": [ [ { "node": "Prepare Telegram Message", "type": "ai_languageModel", "index": 0 } ] ] }, "OpenAI Chat Model3": { "ai_languageModel": [ [ { "node": "Prepare Gmail Message", "type": "ai_languageModel", "index": 0 } ] ] }, "Prepare Gmail Message": { "main": [ [ { "node": "Email Workflow Stats", "type": "main", "index": 0 } ] ] }, "🔎Retrieve Memories": { "ai_tool": [ [ { "node": "🧠 AI Agent w/Long Term Memory", "type": "ai_tool", "index": 0 } ] ] }, "🤖OpenAI Chat Model": { "ai_languageModel": [ [ { "node": "🧠 AI Agent w/Long Term Memory", "type": "ai_languageModel", "index": 0 } ] ] }, "Save Long Term Memories": { "main": [ [ { "node": "Saved response", "type": "main", "index": 0 } ] ] }, "Prepare Telegram Message": { "main": [ [ { "node": "Send Success Message to Telegram", "type": "main", "index": 0 } ] ] }, "🤯Window Buffer Memory": { "ai_memory": [ [ { "node": "🧠 AI Agent w/Long Term Memory", "type": "ai_memory", "index": 0 } ] ] }, "📫Send Memories to Gmail": { "ai_tool": [ [ { "node": "🧠 AI Agent w/Long Term Memory", "type": "ai_tool", "index": 0 } ] ] }, "Retrieve Long Term Memories": { "main": [ [ { "node": "Respond with long term memories", "type": "main", "index": 0 } ] ] }, "Retrieve Long Term Memories2": { "main": [ [ { "node": "Prepare Telegram Message", "type": "main", "index": 0 } ] ] }, "Retrieve Long Term Memories3": { "main": [ [ { "node": "Prepare Gmail Message", "type": "main", "index": 0 } ] ] }, "📤Send Memories to Telegram": { "ai_tool": [ [ { "node": "🧠 AI Agent w/Long Term Memory", "type": "ai_tool", "index": 0 } ] ] }, "When Executed by Another Workflow": { "main": [ [ { "node": "Memory Tool Router", "type": "main", "index": 0 } ] ] }, "Ⓜ️ When chat message received": { "main": [ [ { "node": "🧠 AI Agent w/Long Term Memory", "type": "main", "index": 0 } ] ] } } }
