Verdict
Unstructured is the preprocessing step that every RAG pipeline needs. Documents in the real world are PDFs, scanned images, and Word files — not clean text. Unstructured handles the conversion, OCR, cleaning, and chunking so your RAG pipeline gets properly structured data. For any team building document-based AI applications, Unstructured saves months of preprocessing work.
