Key Features	• Universal Document Partitioning • Structure-Aware Chunking • Table Extraction	• PDF, image, and spreadsheet to Markdown, HTML, or JSON • OCR with layout detection and reading-order reconstruction • Table extraction with bounding boxes preserved

✓Broadest connector library in the document ingestion category — most teams will not outgrow it
✓Genuine Apache 2.0 open-source escape hatch from the managed platform
✓Pre-built destination connectors mean RAG ingestion is wire-and-go for major vector stores
✓Scheduling and incremental refresh are in the box, not bolted-on afterwards

✗Table-extraction accuracy on truly adversarial documents trails specialists like Reducto
✗Platform tier gets expensive once you turn on many connectors and high-throughput parsing
✗Open-source library moves fast — production users need to pin versions deliberately
✗Less precise structured-extraction API than purpose-built tools (Reducto extract, LlamaParse)

✓Citation metadata on every chunk is rare and a real win for compliance-sensitive RAG
✓Apache 2.0 license + self-host option avoids vendor lock-in
✓Table extraction with bounding boxes is materially better than generic OCR
✓Managed and self-hosted SDKs are identical — easy to migrate either direction
✓Designed for LLM consumption, not human reading — chunks drop straight into vector stores

✗Per-page pricing on cloud can add up for very large corpora — model it before committing
✗Smaller community than Unstructured.io; fewer third-party connectors
✗Self-host requires GPU for the layout/OCR models — not laptop-friendly
✗Schema extraction quality is still domain-dependent and may need light fine-tuning
