The honest brief
Chunkr
Grew from a pipeline built to parse ~600M pages of scientific literature, so it holds up on dense, complex document layouts.
- Self-host or call the managed API
- Layout analysis + OCR + semantic chunking
- Outputs HTML, Markdown, or JSON
- Free cloud tier (200 pages, no card)
- Accuracy below Reducto on hard layouts
- Lighter compliance coverage than Unstructured
- Smaller team / younger product
Unstructured
A dedicated pre-RAG ingestion layer with both an open-source library and a managed platform, rather than a one-off parser you wire up yourself.
- 64+ file types ingested
- OCR, tables, hierarchy handled
- Open-source core library
- Low-code platform and API too
- Production RAG staple
- OSS quality trails hosted partition models
- Best results need paid API/platform
- Heavy dependency footprint
- Tuning per document type
