Unstructured

Unstructured is an open-source data platform that converts complex files into structured, AI-ready formats.

Unstructured is a data platform designed to prepare complex documents for language models and artificial intelligence applications. It processes over 64 file types, including scans, images, and multi-page tables, by automatically applying specific parsing strategies. The software preserves reading order, hierarchy, and content accuracy while maintaining low hallucination rates. It serves sectors like finance, healthcare, government, legal, manufacturing, and insurance by converting dense filings, forms, and reports into clean inputs. Users can deploy the system via cloud or private environments to connect data sources directly to vector databases.
