Unstructured — RAG Frameworks Platform
RAG FrameworksLayer 2Open-source + Serverless API + Enterprise PlatformWhat is Unstructured?
Unstructured is the leading data-ingestion and transformation platform for AI applications. The open-source library and hosted Serverless API can ingest, parse, and stage 65+ file formats — PDFs, Word docs, HTML, spreadsheets, emails, images, and more — into clean structured JSON or markdown ready for RAG pipelines and LLM fine-tuning.
The Enterprise Platform layers on a no-code UI, connector ecosystem (S3, Azure Blob, Google Drive, SharePoint, Slack, etc.), advanced chunking and embedding workflows, and production controls: RBAC, organizational accounts, fine-grained permissions, and full compliance with SOC 2, HIPAA, and GDPR. The platform is purpose-built for enterprise RAG ingestion at scale.
Pricing is generous: an Open Source library that's truly free, a Serverless API with 15,000 free pages and pay-as-you-go pricing afterward, and an Enterprise Platform with custom pricing (sales contact required). Unstructured is the most-cited document-ingestion platform in production RAG stacks at large enterprises in 2026.
