Unstructured

Document ingestion and parsing library for converting PDFs, images, and HTML into structured data for RAG

Overview

About Unstructured

Unstructured is an industry-standard data processing library that solves a critical problem in AI: extracting and parsing documents (PDFs, emails, Word docs, HTML pages, images) into clean, structured text suitable for AI applications. Raw documents are messy-they contain formatting, tables, images, and structural elements that confuse AI models. Unstructured extracts meaningful content, preserves document structure, and outputs clean text ready for embeddings, language models, or indexing in vector databases. The library has become essential infrastructure for any AI application that needs to ingest documents, making it the most widely used document processing tool in the AI industry.
