Talk to your patient
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.
Today's clinical case is live
How sharp is your clinical reasoning?
Talk to an AI patient, choose which tests to order, and make the diagnosis.
One new case every day. Under 10 minutes. No multiple choice.
PatientHeyDoctor
One patient. One case. One diagnosis.
No answer choices. No pre-written clues. You decide what to ask, what to investigate, and when you know enough to make the diagnosis.
Order investigations
Labs, imaging, ECGs and more. Choose the investigations you think actually matter. Every result comes from the underlying case data.
Make the diagnosis
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.
1,100+ diagnosesUnder 10 minutes1 new case every day
Don't practice recognizing the answer. Practice finding it.
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.
Think, don't guess
No multiple-choice answers. Every question, investigation and diagnosis comes from you.
Results you can trust
Patient responses and investigation results are grounded in a defined clinical case. Relevant clinical information isn't invented as you play.
Every decision counts
HeyDoctor rewards focused histories and efficient diagnostic workups. More questions and more tests don't automatically mean a better score.
A little practice, every day
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.

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

I'm an internist but I never rotate through everything. @HeyDoctor forces me out of my lane in the best way.
