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
Docling
Self-hostable with AI layout detection that preserves reading order and table structure — no API bills.
- Runs on a laptop via Python API or CLI
- OCR for scans, hybrid chunker built in
- IBM Research origin, now LF AI project
- Wide input format and export support
- Lower accuracy than top hosted parsers
- No managed cloud / SLA out of the box
- Setup and tuning effort vs. an API
- Heavier compute for OCR-heavy docs
