Pros

  • • Supports 25+ document types (PDF, HTML, Office, images) with layout-aware extraction
  • • Semantic chunking with rich metadata (page numbers, element types) ready for RAG
  • • Multiple partitioning strategies (fast, hi_res, ocr_only) for speed/quality tradeoffs

Cons

  • • Heavy optional dependencies (OCR libs, ML models) with platform-specific quirks
  • • Open source version has reduced performance; not recommended for production use
  • • Hi_res strategy is slow on CPU with no GPU support in open source
