Offline triage for community health workers in low-resource settings. Multimodal Gemma 4 + a deterministic safety layer + a WhatsApp handoff to the hub physician — runs entirely on a clinic laptop, no internet.
Scoped to the five grassroots emergencies where minutes matter — Trauma, Poisoning, Snake Bite, MI, and Stroke — Sentinel Health takes a CHW's natural-language description (voice or text), optionally an ECG or wound photo, and produces a triage decision (RED / YELLOW / GREEN), a top-3 differential grounded in a curated knowledge base, a during-transport protocol, and a ready-to-send WhatsApp handoff message to the hub physician.
The whole diagnostic pipeline — multimodal reasoning, safety override, KB grounding, audit log, and escalation message generation — runs on a single clinic laptop. No PHI leaves the device.
