Personal Health Knowledge Graph
A longitudinal timeline per patient, resolved against a standards ontology backbone.
The platform
A patient's history arrives in four incompatible shapes. The Health Context Engine resolves them into a single longitudinal graph, reasons over it against clinical evidence, and returns answers with citations attached.
01Architecture
Nothing here is a black box. Each layer has a defined input, a defined output, and a citation trail that survives clinical review.
02Why it holds up
General-purpose models improvise when the record is thin. A clinical system cannot. January's engine pairs retrieval with deterministic rules so the same question returns the same answer, with the same sources.
88%
Our Health Context Engine outperforms GPT, Gemini, and human clinicians on the endocrine medical board exam. Its proprietary RAG reaches higher accuracy without web access to guidelines and literature.

0.8%
Against 1.8% contradictions, materially below general-purpose frontier models on the same clinical cases (−log₁₀(p) = 8.0 and 8.4).
