LangChain: Smart Text Chunking Without Breaking Context

Problem

RAG (Retrieval-Augmented Generation) applications require splitting documents into smaller chunks for processing.

However, basic text splitting breaks semantic meaning, making your embeddings less effective for retrieval.

Solution

LangChain’s RecursiveCharacterTextSplitter ensures your document chunks maintain meaning and context for better RAG performance.

It intelligently splits text by trying these separators in order:

• Double newlines (paragraphs)
• Single newlines
• Periods
• Spaces
• Individual characters (as last resort)

RecursiveCharacterTextSplitter also allows you to configure the chunk size and overlap to your specific use case.
