Why the models rank Docling — on best self-hosted document parsing software for sensitive data
“Best overall balance of local-first privacy, permissive licensing, installation ease, and high-fidelity extraction of reading order, tables, formulas, code, and document hierarchy; strong PDF, Office, image, and RAG integrations make it the safest default for developers.”
Why the models rank Unstructured — on best self-hosted document parsing software for sensitive data
“Broadest format coverage in one tool (PDF, DOCX, PPTX, HTML, email, images) with partitioning/chunking tuned for RAG pipelines; runs entirely locally via pip or container, so sensitive documents never leave your infrastructure, and its element-typed output saves substantial downstream cleanup.”
