Document Chunking With Overlap

via “configurable chunking strategies with semantic awareness”

SoTA production-ready AI retrieval system. Agentic Retrieval-Augmented Generation (RAG) with a RESTful API.

Unique: Supports multiple chunking strategies (fixed, semantic, code-aware) selectable via configuration, enabling optimization for different document types without code changes. Semantic chunking uses embeddings to identify natural breakpoints, preserving semantic units better than fixed-size windows.

vs others: More flexible than LangChain's fixed-size chunking because it supports semantic and code-aware strategies; more integrated than using external chunking libraries because strategy selection is built into R2R.
