High school student in Japan (Tsuchiura Daiichi High School). Founder of Anshin-Map. I build healthcare tools and study whether AI systems treat people's decisions fairly.
🩺 Anshin-Map — a medical-triage app for the moment of hesitation
When a child spikes a fever at 2 a.m. on a holiday, where should you go — or should you wait? Anshin-Map (Q-suke v3 compliant) helps people, especially parents, make after-hours and holiday healthcare decisions, and returns neutral, trustworthy guidance at the moment they hesitate.
Designed, built, and operated end-to-end (FastAPI · Next.js · PostgreSQL/PostGIS · Claude API) Field trial underway in Tsuchiura City, Ibaraki The core principle: the tool earns trust only if its guidance is genuinely neutral
🔬 Research — is an AI recommender steering your choice?
I run a preregistered audit of whether Anshin-Map's LLM recommendation engine neutrally presents care options or subtly steers users — and whether such steering can be detected from behavior.
800 synthetic personas, a frozen statistical analysis plan, confirmatory tests + bootstrap CIs A manipulation-detection test: inject biased recommendation policies and measure whether the audit catches them Progress: completed the baseline measurement (~3,000 sessions) and the metrics pipeline. Next: patch-injection for manipulation detection and the confirmatory analysis. Preregistration on OSF before confirmatory analysis.
Most of the codebase is private (it touches healthcare, municipal, and personal data). Happy to discuss the design and methodology.
