Standard platforms treat every wrong answer as a generic "Incorrect." Penziv analyzes the specific distractor you chose to understand the cognitive root of the error.
Student Input
Option C: "Decrease dosage"
Time to Answer: 4.2s (Rushed)
Cognitive Engine Detected
Student correctly identified the pathology but ignored the contraindication in the final sentence. Pattern suggests "skimming behavior" on vignette endings.
Most algorithms recommend content based on what the average student finds difficult. For high performers, this causes "regression to the mean," wasting time on concepts you already mastered.
In high-stakes fields like Medicine and Law, accuracy is non-negotiable. We don't use AI to "generate" knowledge from scratch. We use it to compile and curate verified facts from trusted ontologies.

Answer some practice questions. Penziv's engine moves past simple scoring. It analyzes the nuance of every choice, tracking behaviors, habits, and hidden blind spots to build a deep, semantic profile of your knowledge.
Powered by Semantic Distractor Analysis.
As you learn, our system trains a Knowledge Graph Neural Network (KGNN) built just for you. This 'Cognitive Fingerprint' is a living map of your mind, identifying how you connect (or misconnect) concepts.
Tracks unique Learning & Forgetting Rates.
Penziv's Knowledge Tracing engine uses your unique fingerprint to build a dynamic, adaptive study plan. It intelligently balances new material, weak spots, and topics you're about to forget.
Penziv is designed to understand you better than you understand yourself. Like an amazing teacher that understands their studentss. Our engine goes beyond what you know to understand how you think, identifying hidden habits and behavioral blind spots.
We don't just track what you know; we track how fast you learn. Our model calculates a unique 'Velocity of Acquisition' for every subject, optimizing your schedule based on your personal learning speed.
Need to fix a problem before the exam? This high-intensity mode generates a targeted quiz only on the concepts our network has identified as your most critical areas for improvement.
Our QBank isn't just big; it's curated. We use AI to compile and fact-check verified medical information, ensuring high accuracy without the risk of hallucination.
| The "Old Way" (Passive QBanks) | The Penziv Way (Your Agentic Partner) |
|---|---|
"Brute Force": You manually grind through 3,000+ questions, hoping you find your weaknesses. | Precision Targeting: The KGNN identifies high-yield gaps without the volume grind. |
Population Bias: Difficulty is determined by the 'average student,' not your actual ability. | Single-User Graph: Zero collaborative filtering. The model learns your mind exclusively. |
Binary Scoring: Tracks 'Percent Correct' but ignores the logic of *why* you missed it. | Semantic Analysis: We analyze the distractor to tag the types of cognitive failure. |
Static Explanations: Every student gets the same feedback text. | Dynamic Ontology: The graph evolves connections between strengths and weaknesses based on your patterns. |
Manual Triage: You must decide what to study next based on intuition or available resources. | Algorithmic Routing: The Cognitive Elo model mathematically selects the next optimal question. |
