Algorithms That Learn How You Learn

Every answer feeds an integrated system of proprietary algorithms grounded in cognitive science.

Confidence Calibration

Proprietary

Detects dangerous overconfidence through 4-outcome weighting

Confident + Right Confident + Wrong Unsure + Right Unsure + Wrong

Misconception Detection

Proprietary

Flags confident-wrong answers and elevates review priority

Answer Flagged Priority Confident + Wrong Misconception Detected Review Escalated

Exam Readiness

Proprietary

4-factor algorithm with non-linear scaling across domains

Mastery Confidence Consistency Trajectory

Spaced Repetition

6-level mastery system with adaptive expanding intervals

Memory Time R1 R2 R3
Deep dive into our methodology →

See the Difference

Standard apps check right or wrong. Our engine detects dangerous confidence.

We penalize "Confident + Wrong" answers 3x harder than "Unsure + Wrong." This flushes out deep misconceptions before exam day.

!
Misconception Detection Identifies false confidence patterns that standard study apps miss entirely.

Dynamic Weighting Every score adjusts based on your metacognitive input, not just correctness.

Anthony C. Perry, M.S.

Founder & Lead AI Engineer

AI engineer, researcher, and U.S. Air Force combat veteran — building exam prep grounded in the science of how professionals actually learn.

A decorated C-17 Aircraft Loadmaster with 455 combat sorties and the Air Medal, Anthony transitioned from military service into cognitive science research at San Diego State (Cum Laude) and California Baptist (M.S., 3.87 GPA). His graduate thesis on motor learning and cognitive science became the foundation for every Meridian Labs algorithm.

That research now meets cutting-edge AI engineering — with a Master’s in Computer Science (AI/ML) and nearly a decade in technology, he directs advanced generative AI to architect and maintain ten production applications.

Read full bio

Anthony logged over 2,000 flight hours and 455 combat sorties as a C-17 Aircraft Loadmaster across Operations Enduring Freedom, Iraqi Freedom, and New Dawn. He directed airlift for special forces insertions, aeromedical evacuations, dignified transfers of fallen service members, and two presidential support missions for Barack Obama — the kind of work that teaches you something no classroom covers about performing when the stakes are real. His service earned the Air Medal for sustained aerial achievement and the Humanitarian Service Medal for Hurricane Sandy relief operations that reached 8.2 million people.

The same intensity that made Anthony a European track & field qualifier and weightlifting club president eventually pulled him off the field and into the research lab. At San Diego State University — graduating Cum Laude with Distinction in Kinesiology and Dean’s List honors — and California Baptist University (M.S., 3.87 GPA), he studied how the body and brain acquire skill under pressure. His graduate thesis, a randomized clinical trial drawing on 30+ peer-reviewed articles in biomechanics, neurophysiology, and motor learning, became the scientific foundation for every algorithm Meridian Labs ships.

That research foundation now meets cutting-edge AI engineering. With nearly a decade in technology — from fintech infrastructure and AI-driven ventures to a Master’s in Computer Science with an AI/ML emphasis — Anthony operates at the frontier of human-AI collaboration, orchestrating advanced generative AI not as a shortcut but as a precision instrument guided by the domain expertise and cognitive science behind every algorithm. It is this methodology — deep knowledge directing powerful tools — that allows a single engineer-researcher to architect, ship, and maintain ten production applications and 25,000+ exam questions at a standard that neither AI alone nor traditional study methods can match. Trilingual in English, German, and Spanish, and having lived across five countries on four continents, he builds for professionals everywhere who deserve better than guesswork when their careers are on the line.
