The platform runs two assessment modes side by side. Adaptive testing changes question type and difficulty in real time based on each answer, so a student reaches a reliable result in fewer questions. Fixed testing gives everyone the same set, which suits teachers who want a controlled, comparable benchmark. You pick per test.

Diagnostic assessments cover more than the current unit. They trace missing prerequisite knowledge from earlier grades, then plot it on a learning map that shows the shortest path to a goal. Teachers use the report to decide who gets extra support before a new topic starts.

Rather than dumping a pile of problems, the recommendation engine orders questions by the sequence most likely to raise a student's level fastest. This is personalized learning in practice, not a label. Wrong answers get collected and re-served, so weak concepts come back until they're handled. The company calls this fast-track practice.

A tutor named Jello runs on a private LLM with retrieval grounding (RAG is a technique that ties answers to set materials instead of open memory). That keeps replies anchored to source content and cuts hallucination risk. For students, it recommends a learning path and nudges them about unfinished work. For teachers, it assists with class prep and day-to-day tasks.

Real-time dashboards are the core of the teacher experience. You get individual student reports, unit-level achievement breakdowns, a class-wide distribution view, and daily or weekly activity summaries. An AI summary adds plain-language feedback on top of the raw numbers. Simple enough to scan in a minute.

Learning content spans all subjects and all grade levels. The problem and video bank is built for the Korean curriculum, so a school doesn't need separate tools for each subject. Depth per subject can vary.

Leaderboards, quiz battles, progress maps, badges, and item boxes turn learning into something students check on their own. The goal is habit formation, not just scores. Students see exactly where they stand and where they improved.

Schools and larger institutions add single sign-on, white-label branding, platform integration, and a learning-data API. The API is what makes it possible to pull results into an existing school system rather than running two dashboards.
