Ask the questions you'd ask during a real history. The AI patient responds naturally from their clinical case, without knowing or revealing the diagnosis.

Labs, imaging, ECGs and more. Choose the investigations you think actually matter. Every result comes from the underlying case data.

Search across more than 1,100 conditions and submit your answer. You get three attempts, but every question and investigation counts. The more focused your reasoning, the better your score.

Most medical quizzes tell you that the correct answer is somewhere on the screen. HeyDoctor starts with what you'd actually have in front of you: a patient and a problem to solve. Build your differential, decide what information you need, and commit to a diagnosis when you think you have enough.
No multiple-choice answers. Every question, investigation and diagnosis comes from you.
Patient responses and investigation results are grounded in a defined clinical case. Relevant clinical information isn't invented as you play.
HeyDoctor rewards focused histories and efficient diagnostic workups. More questions and more tests don't automatically mean a better score.
One new case each day. Deep enough to make you think. Short enough to fit between rounds, lectures or your commute. Because clinical reasoning gets better with practice.
Try HeyDoctor without a credit card and upgrade whenever you want a new case every day.

One case a day is the habit I didn't know I needed. @HeyDoctor feels like real clinic — not another multiple-choice app.
Attending Physician

I'm an internist but I never rotate through everything. @HeyDoctor forces me out of my lane in the best way.
The scoring nudges you to ask tighter questions. My residents are hooked too.

Board prep that doesn't feel like grinding Anki. @HeyDoctor is the closest thing to a ward encounter I can do on the bus.

We use @HeyDoctor as a quick warm-up before teaching rounds. Same case worldwide = great discussion starter.
Students compare approaches without spoilers until everyone's played.

No NPI, no hospital login — I can actually send this to friends outside the US. The daily format keeps me coming back.

Clinical reasoning isn't MD-only. @HeyDoctor is hard in the right way — you earn the diagnosis.

The investigation picker is *chef's kiss*. Results feel grounded — not like the model is making stuff up.
That trust matters when you're trying to build a real habit.

Under 10 minutes but I think about the case for an hour after. @HeyDoctor nails the curiosity gap.
No. HeyDoctor is for anyone who wants to test or train their clinical reasoning, including physicians, medical students, nurses, pharmacists and other healthcare professionals. No professional or institutional verification is required.
Yes. The Free plan lets you play one full case every week. HeyDoctor Pro is €6.99/week or €14.99/month and gives you a new case every day, the complete archive and Pro features.
Every patient starts with a defined clinical profile. During the conversation, AI uses that information to answer your questions naturally and consistently without revealing the diagnosis.
No. Investigation results are part of the underlying clinical case and aren't invented while you play. AI is used to make the patient conversation feel natural.
Most cases can be completed in around 5–10 minutes. It depends on how many questions you ask and how efficiently you work through the case.
Every case is authored by a physician and reviewed by a second physician before publication. Cases only go live after passing clinical review.
Just a browser. HeyDoctor works on desktop, tablet and mobile. There's nothing to install.
Today's case is already live. Talk to the patient, order your investigations and see how quickly you can reach the diagnosis.
