TL;DR — Unstructured focuses on document ingestion and parsing, turning messy enterprise files into clean chunks for RAG.
What it is
It extracts structured elements from PDFs, docs, HTML, emails, and images for downstream indexing.
Why it exists
Most RAG pain is bad source parsing. Unstructured improves data quality before retrieval.
Install
pip install unstructuredBasic usage
from unstructured.partition.auto import partition
# parse documents into elements
# chunk and push to vector storeWhen to use, when to skip
Use it when this category is a bottleneck in your agent stack and you want faster delivery with fewer custom components.
Skip it when your workload is tiny, requirements are fixed, or a plain provider SDK plus a few local functions is enough.
