What CLASS CARD does
CLASS CARD (클래스카드) is a Seoul-based education technology company that operates a multi-module English learning platform built around a smart flashcard and vocabulary product. The platform serves Korean public school English teachers, private academy (학원) instructors, and their students across elementary, middle, and high school levels, with claims of reaching 1-in-3 Korean English teachers. Core product functionality includes digital flashcard sets with scientific memory methods (spaced repetition, test-enhanced learning, elaborative encoding), AI-powered features (auto-grading of speaking and spelling, AI Grammar Teacher with personalized explanations, one-click test/worksheet generation, computer-vision textbook-to-set capture, and multi-language text-to-speech), real-time Quiz Battle competitions, and an official content library of 26,000 publisher-authorized learning materials from 15+ Korean textbook publishers including NE능률, YBM, 동아출판, 키출판사, 다락원, A*List, and others. The product is delivered as a freemium, tiered subscription (Standard free up to 5 students, Pro at 1,400 KRW/student/month, Max at 2,800 KRW/student/month) across web, iOS, and Android, with distribution driven primarily by teacher community (Naver cafes), seminars, and publisher co-marketing.
The company is led by CEO 김준수 with founder 전성훈 serving as Chief Marketing Officer and Vice President. ClassCard was established in 2016, is incorporated in South Korea as 주식회사 클래스카드, and operates as a privately held, bootstrapped company with no disclosed external venture or private equity funding. Beyond the core ClassCard product, the company has built an ecosystem of sub-brands and modules including ClassCard Grammar (AI-powered grammar training with ~29,372 questions), Listening Training (5,277 CSAT listening questions across 10 years of past exams), AutoVoca (meaning-association vocabulary), Class5 (reading), Quiz Battle (real-time competitions), and Voca Express (proprietary 6,050-word vocabulary textbook introduced in 2026). The business model relies on per-student subscription pricing with no cancellation fees, no disclosed institutional contracts, and concentrated exposure to the Korean domestic K-12 English education market.
