Company profile
researched Aug 2026Classting is a South Korean education technology company that operates an AI-based learning and class management platform for schools. Its core offering, Classting AI, diagnoses an individual student's proficiency level and weak points, then recommends questions and learning paths to close those gaps. The platform combines computer-adaptive testing (CAT), which changes question type and difficulty in real time based on a student's responses, with computer-based testing (CBT), which serves identical items to a whole class so teachers can design a common assessment flow. Supporting features include learning maps, diagnostic assessment reports at student and class level, wrong-answer management that re-serves missed items, a generative-AI question bank, and dashboards for real-time monitoring of class progress.
Alongside assessment, Classting provides an intelligent tutoring layer branded Jello (젤로), described as an AI tutor and teaching assistant that recommends learning sequences, flags unfinished assessments and helps teachers with class preparation. The company states it builds an education-specific large language model using retrieval-augmented generation (RAG) to reduce hallucination and security risks. Self-directed learning features include metacognition tracking of unit-level achievement, gamification, and social learning elements such as learning rankings and journey maps.
The company also runs the Classting class management app for teachers, students and parents, which supports private class creation via invitation codes or URLs, notice boards, class photo albums, assignment creation and submission/grading tracking, sharing of instructional materials for flipped and blended learning, real-time discussion, and an international class exchange feature ("Ting") that connects classrooms in different countries for cultural exchange projects. The app is published under the developer name CT Corp. ((주)씨티) with an address in Gangnam-gu, Seoul, and is available in English, Korean, Japanese, Spanish, Traditional Chinese and Vietnamese.
Founding story
Dave H. Cho worked as an elementary school teacher for four years and concluded that public-school teachers lacked adequate content, tools and resources to teach and evaluate students while carrying additional administrative burdens. He left teaching to start an education service, which became Classting.
Business model
Software platform sold to schools and educational institutions, with a free trial and sales enquiry path for institutional adoption on the company site; the consumer-facing class management app is free to download and carries advertising and in-app purchases (paid passes listed at $29.99–$199.99).
Institutional adoption of Classting AI via contact-sales and free-trial funnels, plus in-app purchases and advertising within the class management app.
Traction
The Korean site states that more than 4,600 schools nationwide use Classting AI, while the English site cites over 26,000 educational institutions using Classting AI. The class management app reports more than 5 million downloads on Google Play with about 62,300 reviews and a 2.3 rating, and roughly 60 ratings averaging 3.6 on the Apple App Store. In 2017 the company reported more than 10,000 pieces of content from over 20 education companies and partnerships with 25 leading content providers.
Latest developments
Current product messaging centers on AI-based diagnosis, fast-track question recommendation, a generative-AI question bank, a RAG-based education LLM, and the Jello AI tutor and teaching assistant, alongside teacher training programs and materials on addressing basic math learning gaps under Korea's 2024 responsible-education-grade policy. The mobile apps continued to receive maintenance releases into 2025 and 2026.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
Positions itself as a provider of AI courseware and adaptive assessment for public education in Korea; was named by Education Technology Insights magazine to its Top 10 EdTech Startups list for 2017 as an LMS and education social network for public schools.
Combines LMS and closed education-focused social networking limited to class members with an adaptive AI diagnostic engine; publishes accuracy metrics for its knowledge-estimation model, offers both adaptive (CAT) and fixed (CBT) testing modes, and applies RAG to constrain an education-specific LLM.
Technology
AI knowledge-estimation and diagnostic engine that the company says reaches up to 91.5% accuracy in predicting correct/incorrect answers and performs under cold-start conditions with limited data, requiring as few as six questions for a diagnosis; computer-adaptive and computer-based testing engines built for large-scale real-time administration; generative AI item creation; a RAG-based education LLM powering the Jello AI tutor and teaching assistant. Earlier descriptions of the platform cite machine learning and deep learning applied to accumulated education data to analyze learning curves and recommend content.
Go-to-market
Direct institutional sales and free trials promoted from the website, downloadable product brochures, teacher training programs and blog/e-book content marketing, teacher testimonials from Korean elementary, middle and high schools, and mobile app distribution through Google Play and the Apple App Store.
K-12 schools, teachers, students and parents, and test administrators needing large-scale adaptive testing; the company has previously targeted public school systems in Korea and other Asian markets.
Geography
Headquartered in Seoul, South Korea (Gangnam-gu address on the app listing), with the Korean school market as its base; the app is localized into six languages and the company previously ran pilots in Taiwan and Japan while negotiating distribution in Singapore, and offers an international classroom exchange feature.
History
The company dates its inception to 2012, initially building a learning management system and a closed educational social network for teachers, students and parents. It launched Classting Learning and consolidated brand recognition around it in 2017, the same year it was recognized among Education Technology Insights' Top 10 EdTech Startups, partnering with content providers and running pilots in Taiwan and Japan. A rebuilt class management app was released in 2022, and the product line has since centered on Classting AI, adaptive testing, generative-AI question generation and the Jello AI tutor.
Risks & controversies
Public app-store feedback is mixed: the Google Play listing shows a 2.3-star average across about 62,300 reviews, with user complaints about persistent loading, sign-in failures, invalid verification codes and account creation problems. School-facing student data handling is a sensitivity, and the listings disclose collection of personal information, usage and advertising data, use of usage data for cross-app tracking, and third-party advertising. The Korean and English sites also state materially different institution counts (4,600 schools versus 26,000 institutions).
