Replacing the Anxiety of the Unknown with the Quiet Confidence of Mastery
Penziv is a study diagnostic for medical students, built by physician-educators and systems engineers. We diagnose why you missed it—connecting your Anki history and cognitive telemetry to reveal the failure patterns behind your missed questions.
Diagnosing Why You Missed It, Not Just That You Did
Anki tells you what you forgot. Qbanks tell you what you missed. Neither tells you why. Penziv operates as the diagnostic layer between them, analyzing ~10 behavioral signals per answer to uncover the exact failure patterns behind your mistakes.
A Wrong Answer Isn't Just Wrong
Every distractor you select reveals the clinical reasoning behind your choice. Instead of a binary score, Penziv maps why you picked it—revealing whether you focused on initial keywords, missed a contradicting lab, or confused look-alike mechanisms.
Pinpointing the 50/50 Split
Most missed board questions come down to the final two options. When you pick the runner-up, you don't need a full chapter review—Penziv isolates the exact clinical discriminator that separates those two look-alike conditions.
Time Pressure vs. Knowledge Gaps
If your last 5 questions were answered in 15 seconds each, you didn't lack knowledge—you ran out of time from overthinking earlier items. We separate pacing fatigue from true knowledge gaps so your mastery score stays accurate.
Leadership & Clinical Pedagogy
Physician-led curriculum design unified with frontier systems engineering.
Justin Whetten
Chief Architect & CEO
Justin brings nearly a decade of engineering R&D and data science leadership from academia and Fortune 500 industry. Holding Graduate and Bachelor degrees in Materials Science and Engineering, he specializes in translating complex multi-modal information streams into low-friction, high-reliability software architectures. With multiple filed patents and technical journal publications to his credit, Justin leads engineering and cognitive interface physics at Penziv—engineering high-density, keyboard-driven study cockpits that eliminate cognitive fatigue for high-stakes examinees.
Jed Whetten
Chief Strategy Officer
Jed is an MD Candidate (Class of 2027) at the University of Arizona College of Medicine – Phoenix with over seven years of medical education, peer mentorship, and clinical curriculum development experience. Serving as a university-appointed Teaching Assistant and Peer Learning Mentor across Advanced Anatomy, Human Physiology, and Biochemistry, Jed works to bridge foundational basic sciences with acute bedside diagnostic reasoning. As Chief Strategy Officer at Penziv, he guides pedagogical architecture—ensuring every differential matrix, cognitive pacing metric, and distractor rationale is anchored in validated cognitive learning science and ACGME competency standards.
Designed for Clinical Competence & Board Excellence
Every question interface, differential matrix, and pacing telemetry metric is engineered against validated cognitive science and medical education benchmarks.
Cognitive Load Optimization
Constructed on Sweller's Cognitive Load Theory to strip extraneous visual friction, focusing working memory squarely on clinical differential formulation.
ACGME Competency Alignment
Reinforces Practice-Based Learning & Improvement and Medical Knowledge through systematic error-forensics and root-cause self-attribution.
Dual-Coding Differential Matrices
Directly compares look-alike clinical syndromes and high-yield discriminators for robust long-term retention.
Pacing & Decision Calibration
Analyzes pacing trends, second-guessing patterns, and anchoring habits to help future physicians develop disciplined, evidence-based diagnostic conviction.
