Ever wondered how to supercharge your chatbots and make them remember things like an elephant? Well, you’re in luck because today we’re diving deep into the Chat Memory Manager node in n8n. This little powerhouse is your secret weapon for managing chat messages like a pro, and I’m here to show you exactly how it’s done.
What’s the Chat Memory Manager Node All About?
Let’s get straight to the point: the Chat Memory Manager node is your go-to tool for handling chat messages within n8n workflows. It’s like the brain of your chatbot, helping it keep track of conversations and respond intelligently. Whether you’re building customer support bots, interactive voice assistants, or anything in between, this node is essential for advanced chat message management.
So, what can it do? A lot, actually. It lets you load, insert, and delete messages in an in-memory system. This is super handy when you can’t add a memory node directly or need more complex memory management. Plus, it can check and reduce the memory size of the Agent node’s response, ensuring your bot stays efficient and doesn’t get overwhelmed.
How to Use the Chat Memory Manager Node
Now, let’s talk about the nitty-gritty of using this node. It supports three operation modes: Get Many Messages, Insert Messages, and Delete Messages. Each mode has its own set of options and capabilities, so you can tailor your memory management to fit your needs perfectly.
- Get Many Messages: Use this mode to retrieve multiple messages at once. You can simplify the output to include only the sender and text, making it easier to process and analyze.
- Insert Messages: This mode lets you add new messages to your chat history. You can choose between inserting messages alongside existing ones or overriding all messages. Plus, you can define the message type as AI, System, or User, and even enter the message content yourself.
- Delete Messages: Need to clean up your chat history? This mode allows you to delete the last N messages or all messages. You can specify the number of latest messages to delete when choosing Last N, giving you precise control over your chat memory.
But wait, there’s more! You can also inject messages that appear as user messages to provide additional context to the AI. This is a game-changer for creating more personalized and relevant responses. And if you want to keep some messages hidden from the chat UI, you can do that too.
Sub-Nodes and Expressions
Here’s a little tip: sub-nodes in n8n behave differently from other nodes when processing multiple items using expressions. In sub-nodes, expressions always resolve to the first item of the input. It’s a small detail, but it can make a big difference in how your workflows operate.

To help you get started, n8n provides some awesome templates and examples. For instance, you can check out the “Chat with OpenAI Assistant” template or the “AI Voice Chat using Webhook, Memory Manager, OpenAI, Google Gemini & ElevenLabs” example.
