Company Overview

PrepMaster Inc. is a Seoul-based AI-powered EduTech venture founded in 2023, specializing in high-stakes relational reasoning assessment. Leveraging 23 years of domain expertise in SSAT preparation, we have developed a proprietary 55-Logic Taxonomy and 75-Trap Matrix deployed as dual-constraint conditions within a 4-Layer AI generation and validation pipeline. Our technology automates the creation and verification of premium reasoning content at a quality level no general-purpose LLM can replicate — targeting the global high-stakes assessment market that remains untapped by Big Tech.

"

PrepMaster's mission is not to replace subject-matter experts with AI, but to transform 23 years of tacit domain knowledge into formalized AI-readable logic — realizing a human–AI collaboration model where both grow together.

Core Product
PairUp! — AI Socratic Scaffolding Platform
An adaptive reasoning-correction platform that diagnoses errors in real time using the 75-Trap Matrix, then delivers a three-stage Socratic hint sequence (retrieval cue → logic reconstruction → metacognitive reinforcement), guiding learners to rebuild their own reasoning structures. Designed for SSAT, SAT, GRE, GMAT, and LSAT.
