Docling

Docling extracts structured text from documents that other parsers mangle. PDFs with complex layouts, scanned images, DOCX files with embedded tables — it handles the messy reality of real-world documents that feed RAG pipelines.

For document ingestion pipelines, it's essential. The output quality directly determines the quality of your embeddings and retrieval. We run Docling as a microservice in our RAG stack, processing uploads before chunking and embedding. The alternative is writing custom parsers for every document format — Docling eliminates that entirely.
