# Langchain

> Leverage Langchain components with Neum AI

<Warning>These capabilities are currently in beta. Please contact [founders@tryneum.com](mailto:founders@tryneum.com) with any questions or asks. <br /><br /> Only supported for local development. Not supported for Neum cloud.</Warning>

## Document Loaders

Langchain offers a variety of [document loaders](https://python.langchain.com/docs/modules/data_connection/document_loaders) for many sources. Langchain loaders have a similar `load` method to Neum data connectors. The output of the method is a Langchain Document vs a Neum Document. We offer helpers to transform documents.

```python
!pip install neumai-tools

from neumai_tools.InteropHelpers.DocumentTransformer import document_transformer_langchain
from langchain.document_loaders import TextLoader

loader = TextLoader("./index.md")
documents = loader.load()

neum_documents = [document_transformer_langchain(document) for documents in documents]

```
