Hummingbird™ - Unlock the Evidence Buried in Clinical Notes

Extract research ready variables from unstructured sources – efficiently, securely, and at scale. 

Accuracy That Generalizes
--------

01
Hummingbird™ matches LLM-level accuracy and F1 performance using proven clinical NLP methods, validated in peer-reviewed research across use cases.

Cost Efficient Extraction--------

02
Built for standard compute environments, Hummingbird™ turns unstructured clinical notes into structured data without relying on GPUs or external processing power.

Privacy by Design, Deployed Anywhere

03

Hummingbird™ runs on CPUs only and never contacts frontier LLMs, keeping institutions in control of their data wherever it is deployed.
