Empower Your AI Agent with Long-Term Memory and External Tools
detail.loadingPreview
This n8n workflow acts as a powerful 'tools router' for your AI agents and chatbots, enabling them with critical long-term memory capabilities and external communication channels. Integrate seamlessly with LangChain to give your AI the power to remember, recall, and interact beyond its immediate context.
About This Workflow
Unlock the full potential of your AI agents by equipping them with persistent memory and external communication tools. This n8n workflow provides a robust framework for an AI agent to save and retrieve long-term memories using Google Docs, effectively giving your bot a history to learn from. Furthermore, it enables the AI to send updates or information to external platforms like Telegram and Gmail, extending its utility beyond conversational boundaries. Designed with LangChain tool integration in mind, this router workflow makes complex AI interactions simple and manageable, allowing your AI to make informed decisions and act on them.
Key Features
- AI Agent Tool Integration: Easily expose powerful functionalities as tools to your AI agent, especially designed for LangChain-based applications.
- Persistent Long-Term Memory: Utilize Google Docs as a reliable storage for your AI's memories, allowing it to remember past interactions and information.
- Memory Retrieval & Recall: Enable your AI to effortlessly retrieve relevant historical data, enhancing its contextual understanding and personalized responses.
- External Communication Channels: Empower your AI to send messages to Telegram and emails via Gmail, facilitating proactive communication or notifications.
- Flexible Routing for AI Actions: A central hub to intelligently route different AI agent requests to specific actions, ensuring efficient and targeted responses.
How To Use
- Workflow Trigger: This workflow is designed to be called by another n8n workflow or an AI agent framework (like LangChain) that utilizes custom tools. Ensure your calling mechanism passes relevant input (e.g., a query to save or retrieve memory).
- Google Docs Setup: For
Save Long Term MemoriesandRetrieve Long Term Memories3nodes, configure your Google Docs OAuth2 credential. Specify thedocumentURLfor the Google Sheet/Document where memories will be stored. - Telegram Integration: To use the
Send Success Message to Telegramnode, set up your Telegram API credential. Define theTELEGRAM_CHAT_IDas an environment variable in your n8n instance. - Gmail Integration: For the
Email Workflow Statsnode, configure your Gmail OAuth2 credential. Set the recipient email address using an environment variable likeEMAIL_ADDRESS_JOE. - LangChain Tool Configuration: The
toolWorkflownodes (e.g.,🧠Save Memories,🔎Retrieve Memories) expose this workflow's functionalities as tools. When integrating with an AI agent (like LangChain), provide these tools to your agent, ensuring therouteparameter matches the internal logic defined in these nodes (e.g.,save_memory,retrieve_memory,send_memories_to_telegram,send_memories_to_gmail). - OpenAI Models: The OpenAI Chat Model nodes are present for processing input or generating responses within the workflow. Ensure your OpenAI API credential is configured.
