LangChain Memory Nodes

Memory

---

Memory allow you to chat with AI as if AI has the memory of previous conversations.

Human: hi i am bob

AI: Hello Bob! It's nice to meet you. How can I assist you today?

Human: what's my name?

AI: Your name is Bob, as you mentioned earlier.

Under the hood, these conversations are stored in arrays or databases, and provided as context to LLM. For example:

You are an assistant to a human, powered by a large language model trained by OpenAI.

Whether the human needs help with a specific question or just wants to have a conversation about a particular topic, you are here to assist.

Current conversation:
{history}

Memory Nodes:

• Buffer Memory
• Buffer Window Memory
• Conversation Summary Memory
• Conversation Summary Buffer Memory
• DynamoDB Chat Memory
• MongoDB Atlas Chat Memory
• Redis-Backed Chat Memory
• Upstash Redis-Backed Chat Memory
• Zep Memory

Separate conversations for multiple users

UI & Embedded Chat

By default, UI and Embedded Chat will automatically separate different users conversations. This is done by generating a unique chatId for each new interaction. That logic is handled under the hood by Flowise.

Prediction API

You can separate the conversations for multiple users by specifying a unique sessionId

1. For every memory node, you should be able to see a input parameter Session ID

2. In the /api/v1/prediction/{your-chatflowid} POST body request, specify the sessionId in overrideConfig

{
    "question": "hello!",
    "overrideConfig": {
        "sessionId": "user1"
    }
}

Message API

• GET /api/v1/chatmessage/{your-chatflowid}
• DELETE /api/v1/chatmessage/{your-chatflowid}

Query Param	Type	Value
sessionId	string
sort	enum	ASC or DESC
startDate	string
endDate	string

All conversations can be visualized and managed from UI as well:

For OpenAI Assistant, Threads will be used to store conversations.
