spokest-langchain

LangChain memory integration for Spokest Brain. Give your LangChain chains persistent, associative memory powered by the Spokest Brain API.

Install

pip install spokest-langchain

Usage

from langchain_openai import ChatOpenAI
from langchain.chains import ConversationChain
from spokest_langchain import SpokestMemory

memory = SpokestMemory(
    api_key="sk-your-spokest-api-key",
    base_url="https://brain-api.spokest.com",  # optional, this is the default
)

llm = ChatOpenAI(model="gpt-4o")
chain = ConversationChain(llm=llm, memory=memory)

response = chain.invoke({"input": "What did we discuss about the product launch?"})
print(response["response"])

Configuration

How it works

• load_memory_variables -- Calls /v1/memory/recall with the current user input to retrieve relevant memories. Returns them formatted as a bulleted list under the configured memory_key.
• save_context -- Calls /v1/memory/store with the full conversation turn (user input + assistant output) after each chain invocation.
• clear -- Logs a warning. Spokest Brain memories are permanent by design and cannot be deleted.
