Cardiology · Clinical Reasoning
A 58-year-old presents with sudden tearing chest pain, BP differential 40 mmHg between arms. ECG clear. Most likely diagnosis?
Cognitive Autopsy
Anchoring
You fixated on the chest pain presentation and missed the bilateral BP differential — the decisive dissection clue.

Cognitive Autopsy
Fixated on “combat veteran” — assumed the question was about aggression. It was about PTSD.
A weakness heatmap by topic and a forgetting-curve schedule bring concepts back the moment you'd lose them.

Chat with your material
Every uploaded document becomes a conversational knowledge base. Ask questions in plain language, get cited answers pulled from your own material — then drill deeper without switching tools.
Paragraph-level citations
Every answer links to the exact paragraph in your source — not just a page number.
Grounded in your material only
No hallucinations — the AI only answers from what you uploaded.
Works alongside your quizzes
Use chat to clarify concepts from your study material — all from the same document, no switching tools.
“ACE inhibitors competitively inhibit the angiotensin-converting enzyme, preventing the cleavage of angiotensin I to the vasoactive angiotensin II, thereby reducing systemic vascular resistance and aldosterone-mediated sodium retention.”
The Cognitive Autopsy
Normal MCQs tell you what you got wrong. Cognitive Autopsy MCQs tell you exactly where your reasoning broke down — so you fix the thinking, not just the fact.
Fact-checks you
When you get a question wrong, you get a paragraph explaining the correct answer. You know what's right. You still don't know why your gut got it wrong.
Diagnoses your thinking
Every answer gets a reasoning analysis. The system identifies the specific cognitive error pattern behind your choice — so you can correct the root cause, not just memorise the answer.
When you select a wrong answer, the system gives you two layers of analysis:
Primary Error
The main flaw in your clinical reasoning
The core mistake in how you processed the clinical information — the step where your reasoning chain broke.
Secondary Error
The mental trap or bias that led you there
The underlying cognitive bias or shortcut that caused the primary error — the pattern to watch for next time.
Every mistake is classified into one of four types — so you can recognize your own patterns.
Overthink & Anchor
You fixate on one salient detail and ignore the rest of the clinical picture. One word hijacks your entire reasoning chain.
Missed the Clue
You overlook a key piece of information in the stem. The decisive detail was there — you just didn't register it.
Wrong Mechanism
You identified the right system or domain but chose the wrong mechanism or treatment. Right neighbourhood, wrong address.
Incomplete Reasoning
You stopped thinking too early. You treated the loudest symptom rather than reasoning to the underlying condition.
The key idea
This system is not just about getting more questions right. It is about understanding your thinking patterns and correcting them — so that better clinical reasoning becomes automatic, not effortful.

Who it’s for
For medical students
USMLE / PLAB / MRCP questions generated from your own coursework, with the Cognitive Autopsy that names the diagnostic error pattern behind every miss.
For knowledge workers
Turn internal docs, RFCs, and onboarding decks into role-tailored quizzes. Measure team comprehension before launch, not after the postmortem.
Loved by learners
QuizEngine caught a thinking pattern I didn’t know I had. The Cognitive Autopsy on every wrong answer is genuinely a different way of learning — it’s the first tool that told me why I keep getting the same questions wrong.
