Train your clinical
reasoning with AI
Practice realistic patient cases across all medical specialties. Get instant feedback on your diagnostic logic and clinical decisions.
Three steps to sharper reasoning
From choosing a specialty to getting a detailed competency score — all in under 15 minutes.
Pick a specialty
Choose from 12+ specialties or let the AI surprise you with a random case. Set your training level from MS1 to attending.
Work the case
Take a history, order tests, interpret results, and make management decisions. The AI patient responds realistically to every choice.
Get scored
Receive a structured debrief scoring 5 competency axes: history, differential, workup, management, and clinical reasoning.
Try it now — no account needed
Interview the patient, make clinical decisions, and see how LucidCases works. A small taste of the full experience.
A 62-year-old woman presents to the ED with sudden onset of severe headache she describes as "the worst of my life." She has mild neck stiffness and photophobia. BP 168/92, HR 88, T 37.2°C. GCS 15.
How it works: First, interview the patient to gather clinical information. Then, make your clinical decisions. No account needed.
Built for how doctors actually learn
Not flashcards. Not MCQs. Real clinical reasoning under pressure.
Adaptive AI Attending
The AI acts as an attending physician — responding to your questions, orders, and decisions in real time. Every case unfolds based on your choices.
Structured Feedback
After each case, receive a detailed debrief on history taking, differential diagnosis, workup, and management — scored on 5 competency axes.
Track Your Growth
Longitudinal competency tracking across specialties. See exactly where you're improving and where your blind spots are over time.
Infinite Cases
No two cases are identical. The AI generates realistic presentations with authentic vital signs, labs, and imaging — drawn from real clinical patterns.
Any Specialty
From Emergency Medicine to Dermatology. Switch specialties instantly or let the system challenge you with unfamiliar territory.
Spaced Repetition
Flashcards and MCQs generated from your cases. SM-2 algorithm schedules reviews so key concepts stick in long-term memory.

What learners are saying
From medical students to residents — real feedback from real clinicians in training.
“LucidCases completely changed how I prepare for clinical rotations. The AI attending pushes my reasoning in ways textbooks never could.”
“I run 2-3 cases on the train every morning. My attendings noticed the improvement in my differentials within weeks.”
“The spaced repetition flashcards from my own cases are brilliant. I retain so much more than with Anki decks alone.”
“As an IMG without easy access to clinical practice, LucidCases gives me the closest thing to real patient encounters.”
