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
Pulse
Built its own OCR + layout + vision stack (the Ultra model) for messy financial, medical, and legal documents, rather than wrapping a general LLM.
- Purpose-built models for hard layouts
- Handles PDFs, Office files, scans
- Free sandbox to evaluate
- Used by large enterprises
- Cloud-only (no self-host)
- Self-serve pricing not public
- Closed-source models
