About Unstructured
Unstructured, from Unstructured-IO, turns complex documents such as PDFs, HTML, Word files, emails and images into clean, structured output for language models and AI agents. It is available as an Apache-2.0 open-source Python library and as a commercial platform with managed pipelines and a Transform API/MCP interface.
What It Is
Unstructured is a document pre-processing and ETL toolset for GenAI data. The open-source unstructured library provides a partition function that detects the file type and routes it to the matching partitioning function, returning document elements. It can be installed from PyPI with extras per document type, or run from a Docker image. Some document types require system dependencies such as poppler, tesseract and libreoffice.
Platform pipeline: extract, transform, load
The vendor's platform page describes an end-to-end pipeline. It connects to 30+ sources, transforms 65+ file types with partitioning strategies that adapt per page, applies chunking, enrichments (such as image descriptions and entity recognition) and embeddings, then loads results to 30+ destinations including vector and graph databases, search engines and blob storage. Workflows can be scheduled and skip files already processed. They can be driven through an API, a no-code UI, or MCP for AI agents.
Deployment and compliance
The company says the platform can run as managed SaaS, hybrid, in a customer VPC, or on bare metal. It lists SOC 2 Type 2, HIPAA, GDPR, ISO 27001 and FedRAMP High among its compliance credentials. It also describes organizational accounts, role-based access and fine-grained permissions.
Open source versus Transform
The README states the open-source library will stay free and points to the Transform v2 API for higher-quality output. It reports Transform scoring higher than the open-source library on table accuracy and text accuracy in its own benchmarks. The library sends lightweight anonymous telemetry by default, which can be disabled with the DO_NOT_TRACK or SCARF_NO_ANALYTICS environment variables.
