Medero

Medero: healthcare without language barriers. When you're sick in a country whose language you don't speak, the clinic is the hardest place to be understood. You can't explain your symptoms. You can't tell whether the doctor asked a question or made a decision. And afterwards you're handed papers you can't read: the prescription form I got in Korea expired in 3 days, the pharmacy keeps it, and the disease-code box my insurer needed was left blank. Nobody told me any of that. Medero is a phone app that speaks Korean to the clinic on your behalf, without ever speaking for you: - Before the visit: you describe how you feel in your own language. Medero shows which clinic sign to look for (e.g. 안과, eye clinic) and opens a map search. It builds a case card, and you approve each fact it may say. Anything you leave blank stays "unknown", never "no". - During the visit: Medero tells staff it's an AI and asks permission first. Then it listens hands-free: Korean is the doctor, your language is you. It answers only from approved facts. Anything new, and every decision (consent, treatment, payment), comes back to you as a question. Emergency words stop everything and show a fixed 119 / 1339 card. - After the visit: a summary of only what the doctor said. A reminder to ask for the disease code and itemized bill while you're still at the desk. The prescription form read as printed (doses, days, no-substitute, not-covered, validity), always with "confirm with the pharmacist". An insurance checklist built from your insurer's own document, showing what's still missing. Medero never diagnoses or gives medical advice. It's a communication and navigation tool. A deterministic verifier blocks any Korean reply that isn't backed by an approved fact, and every translation is checked for changed numbers or a flipped "not". Korea is the first market; the patient side works in English and Thai. All demo data is mock. Live: https://medero-pi.vercel.app Code: https://github.com/Passavee-Losripat/medero
