HeyDoctor: Clinical Cases

Diagnose one AI patient a day. Now with smarter diagnosis search, partial credit for near misses, and a brand-new glass design.

Wordle meets a real clinical encounter, one new case every day.

HeyDoctor isn't a quiz. There are no multiple-choice clues handed to you in order. You sit across from a patient who says "my chest hurts," and it's on you to figure out what to ask next.

HOW IT WORKS

• Talk to an AI patient in plain language, just like a real consultation. They know their symptoms, not their diagnosis — and they never volunteer information.
• Order the tests you'd actually run: bloods, imaging, ECGs. Results come straight from the validated case file, so there are no made-up lab values.
• Submit your diagnosis from a database of 1,100+ conditions across 20 specialties. You get three attempts.
• Every question and every test costs points. Fewer questions, higher score. Can you crack it in under 10 messages?

A NEW CASE EVERY DAY One global case drops at midnight. You have 24 hours. Build a streak, compare with friends, and keep your clinical pattern recognition sharp in five minutes a day.

BUILT ON REAL CLINICAL REASONING Every case is authored by a physician and reviewed by a second physician before it goes live. The AI patient is grounded in a structured clinical profile — it never invents symptoms and never reveals the diagnosis.

WHO IT'S FOR Medical students, junior doctors, nurses, pharmacists, and anyone curious about how diagnosis really works. No NPI, no institutional login, no verification. Open to everyone.

FREE & PRO Play one case per week for free. HeyDoctor Pro unlocks a new case every day, the full archive, and more.

History-taking, hypothesis testing, investigation ordering, efficiency under uncertainty — the full arc of clinical reasoning, not just pattern matching.
