Which one?
Pick Unstructured if
- you want the stronger public evidence (66 vs 64)
Best for a RAG pipeline that has to swallow a company's whole file share.
Pick Docling if
- you need it on windows
- a bigger GitHub community matters (69,684 vs 15,628 stars)
Best for feeding your own documents to a model without uploading them.
