01
A case opens.
A patient, a setting, a presenting complaint. Nothing more.
Clinical simulation platform
The only way to get better at clinical reasoning is to practice it on patients. Until now.
Osler is a clinical simulation platform. Present a patient, take a history, order investigations, make a call, and see what happens. No risk. No shortcuts.

The gap
There is no safe environment to be wrong in medicine.
You learn to reason by doing it on real patients, which means your early mistakes have real consequences and your later ones happen in isolation, with no feedback loop to catch them.
CME is passive. QBanks test recall. Neither builds the skill that actually determines clinical outcomes: the ability to reason well under uncertainty.
Osler exists because that gap has never been closed, and now it can be.
What Osler is
A simulation of clinical practice. Not a test of clinical memory.
In Osler, medicine works the way it does in reality. You ask for a history, you get one. You order an ECG, you get the result. You prescribe a treatment and the patient responds, or does not.
No shortcuts
No pre-selected options, guided prompts, or textbook on the side.
Evaluates how you think.
The platform looks at what you asked, what you missed, what you over-investigated, and where your reasoning diverged from evidence-based practice.
LeetCode's logic, applied to medicine.
A well-defined case exposes exactly how a clinician thinks under uncertainty, with immediate feedback and measurable improvement.
02
You practice medicine.
Ask questions, examine, and order investigations. The simulation responds to what you do.
03
You commit.
Make a diagnosis and management plan in your own clinical language.
04
The debrief.
A precise account of what was sound, what drifted, and what the evidence says.
Feedback loop
Not a grade. A precise account of how you think.
Your performance is tracked, rated, and benchmarked against peers. The competitive layer exists because consistency is how reasoning improves.

Who it is for
Built for clinical minds at every stage.
Students and NEET PG aspirants
NEET PG is a reasoning exam. Preparing for it with a recall tool is the wrong instrument. Osler trains the underlying skill the exam is actually testing.
Residents and practicing doctors
Clinical reasoning does not plateau after medical school. Osler creates deliberate exposure to cases outside the daily caseload, without consequence.
Early access
Osler is in development. Early access opens soon.
