Ditch the noise, keep the confidence.
Penziv is your private tutor that finally sees you. It studies your missed questions or your synced Anki deck to find the hidden patterns behind your misses and the strengths behind your makes, so you never have to study blind again. Then its dynamic Qbank aims board-style questions directly at your weak spots, so every minute you study makes the next one count more.
What it actually does
Reads every review you've ever done.
Every card, every lapse, every answer button — analyzed on your machine. Nothing uploaded.
Finds patterns, not cards.
Topics failing denser than your own baseline. Topic pairs failing at ~2× baseline risk. Overconfidence quadrants. Session fatigue. Fragile knowledge that looks solid and isn't.
Explains your thinking back to you.
~10 behavioral signals per answer — timing, eliminations, answer switches, highlights, your own notes — written up as severity-ranked strengths and weaknesses. No fixed categories.
Reviews done. Backlog cleared. Then the vignette blanks you.
You can recite the card and still miss the question — because boards don't test cards. They test multi-step reasoning under a vignette, and no amount of re-reviewing everything finds the specific reasoning breakdown that's costing you points. So you do more reviews. The pile grows. The gap stays.
The loop: history → patterns → quizzes → forensics → back to Anki
Five connected phases turning your review history into targeted clinical reasoning.
1. It reads your history, not your cards
Connect your collection in one click through the free add-on — or a 6-digit sync code, or a .apkg upload. Penziv reads your entire review history and hunts for failure patterns: the largest shared weaknesses across your cards.
- Personal Baseline: Topic failure density measured against your own historical baseline, not an arbitrary class average.
- Toxic Topic Pairs: Pinpoints look-alike disease pairs failing at ~2× baseline risk before you confuse them on exam day.
- Fragile Knowledge: Surfaces cards that look mature but answer slowly — catching hidden rot before the exam catches it.
2. Your worst patterns become your next quiz
The top patterns don't sit on a dashboard. They convert directly into targeted board-style quizzes — the pattern's topics, name, and context travel with you, and the quiz opens by naming the pattern you're attacking.
Your Anki history writes your study plan. Instead of grinding question banks blindly, you attack the 5% of material actively failing.
Identified across 14 struggle cards. Quiz generated targeting the exact discriminator lab values.
3. Every answer gets read like a forensic file
Each question captures ~10 behavioral signals: your answer, your timing, which options you eliminated — including whether you struck out the correct one — your answer switches with timestamps, your highlights, and your notes.
- Severity-Ranked Analysis: Diagnoses your thinking back to you as prioritized strengths and weaknesses without rigid taxonomy boxes.
- Nuanced Evaluation: A wrong answer can still show clean reasoning; a fast correct answer can expose superficial keyword skimming.
4. One answer moves many topics
Every answer updates your mastery — not just on that question's topics, but sideways into related ones through concept similarity. One cardiology question nudges renal physiology when the underlying hemodynamic mechanism overlaps.
Your mastery map is alive: it reshapes with every answer, and your next quiz is built from it — targeting roughly 75% correct, hard enough to learn from, easy enough to stay in the game.
5. The loop closes back in Anki — only by your hand
From your results, flag or suspend struggle cards with one tap — the tap is the confirmation: no Anki Desktop dialog, no background writes. Re-test strong and the flag clears.
Nothing is automatic. Penziv touches flags and queue state only. It never touches your intervals, due dates, FSRS parameters, or tags. Your scheduling stays yours.
The Diagnostic Engine for Your Brain
Stop guessing about your retention. Use our forensic tools to audit your study habits, triage sick cards, and optimize your cognitive load.
Anki Deck Audit & FSRS Optimizer
Connect Anki Desktop in 1 click via our lightweight add-on (Tools > Sync with Penziv) to audit your true mature retention, isolate high-risk struggle cards, and calibrate your optimal FSRS parameters.
Clinical Ward Tools
Essential calculators for your rotations. Fast, free, and evidence-based.
Three steps. No new workflow to learn.
You keep studying exactly how you study. Penziv just aims it.
Connect your Anki collection
One click through the free add-on (or 6-digit sync code, or .apkg upload). Your review history becomes your personal diagnostic baseline.
See your failure patterns
Ranked by damage. Penziv isolates the 5% of material actually failing — not the 95% that's already fine.
Drill them with targeted vignettes
Quizzes built directly from your patterns. Cognitive forensics on every answer. Verdict returned to Anki with one tap. Nothing written without your consent.
Official Exam Topics, Blueprints & Pass Criteria
Review full blueprint weightings, clinical task competencies, and examination criteria for USMLE Step 1 & 2 CK, NCCPA PANCE (PA School), and core NBME Shelf examinations.

Mechanism Over Memorization
Flashcards drill isolated facts; board exams test multi-step clinical reasoning. Penziv identifies the exact cognitive breakdowns that cost you points on patient vignettes.
Living Mastery Map
Mastery propagates across related physiological mechanisms in real time. One cardiology question updates renal hemodynamics when concepts overlap.
Pattern-Fed Quizzes
Instead of grinding question banks blindly to find your blind spots, your worst Anki failure patterns write your exact next study block.
Zero Scheduling Writes
Penziv never tampers with your intervals, due dates, FSRS parameters, or tags. Every flag or queue change happens only with your explicit one-tap consent.
Anki tells you what you forgot. Qbanks tell you what you missed. Neither tells you why.
Penziv isn't another Qbank or flashcard app. It's the diagnostic layer between them.
