l POSTMATH

POSTMATH is a Korean education technology company building tools to help mathematics teachers save time and focus on teaching. Its mission is to improve education by addressing teachers’ practical challenges, reducing learning gaps, and supporting more personalized instruction through technology and data. The company offers Math Secretary (수학비서), a mathematics content and question-bank platform, alongside PostGeo, a tool for editing geometric figures while preserving their properties.

POSTMATH’s technology goes beyond basic question libraries. Its OCR recognizes printed math problems even when handwriting or annotations are present, while adaptive tagging organizes questions across curricula. Dynamic Semantic Structuring (DSS) structures information from textbooks and reference books to improve search and reuse. Review OMR uses learner feedback to identify useful questions for targeted review worksheets. PostGeo supports geometry editing, and LDM matches mathematically similar diagrams. The company also uses a Math Ontology that connects questions with mathematical concepts through shared tags.

By organizing educational content and learning data, POSTMATH aims to help teachers create more tailored learning experiences.
