Unstructured.io is an open-source Python library and API service designed to preprocess documents for AI applications, particularly Retrieval-Augmented Generation (RAG) pipelines. Released in 2022 and currently at version 0.17.0, it excels at converting messy real-world documents like PDFs, Word files, and presentations into structured JSON elements. The library's pipeline involves partitioning documents into elements, cleaning them, and then chunking them into semantically meaningful pieces with rich metadata, significantly improving retrieval accuracy compared to basic text extraction methods.
