ConcussionCompanion

Patients feel symptoms precisely but can't name them clinically — so doctors get noisy, incomparable data from weeks-old recall. Concussion Companion closes the gap: patients describe their day by voice, and an agentic Symptom Manager annotates their words like a teacher grading an essay — mapping each phrase to Post-Concussion Symptom Scale / SNOMED terms, teaching the vocabulary as a side effect, and asking at most three function-anchored follow-ups. Clinicians open the next visit to five weeks of standardized 4-axis recovery data instead of "how have you been?" Concussion-first, built from lived experience, extensible to chronic care.
