The honest brief
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
Unstract
Prompt Studio offers a no-code IDE to build and test per-field extraction prompts, then deploy them as APIs or ETL pipelines — and the whole stack self-hosts.
- Open-source (AGPL-3.0), self-hostable
- Prompt Studio: no-code extraction IDE
- Deploy extractions as APIs or ETL
- Cloud adds SOC 2 / HIPAA / HITL review
- AGPL-3.0 may deter some commercial use
- Self-host setup is involved
- LLM costs scale with document volume
