Pros
- • Supports 25+ document types (PDF, HTML, Office, images) with layout-aware extraction

- • 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
