Overview

Most RAG quality problems start at ingestion. This course, built with Unstructured.io, teaches document parsing across formats — PDFs, PowerPoint, HTML, and images — plus chunking strategies, metadata extraction, and normalization. You build a pipeline that turns heterogeneous enterprise documents into consistent, searchable chunks, which is the foundation any good retrieval system depends on.
