한 (Han) — AI Korean Tutor

Master Korean with an AI that knows you — vocab, grammar, reading, listening, speaking and writing in one personal path.

Overview

한 (Han) is an AI-powered Korean learning platform that adapts to how each learner actually studies. It blends spaced-repetition flashcards, a personal vocabulary library, grammar breakdowns from real textbooks, AI-generated reading and listening passages, writing feedback and a real-time AI tutor into one connected daily plan — instead of forcing learners to juggle separate apps for each skill.

The problem

Most Korean learners end up using five or six disconnected tools — one for flashcards, one for grammar, another for reading, another for speaking practice. Progress is scattered, repetition is generic, and there's no single view of what to study today or what's actually weak.

The solution

한 unifies the full learning loop around a personal vocabulary and grammar library. The AI tutor uses what the learner has saved to generate context-aware drills, reading passages, listening hints and writing feedback — and recommends each day what to review next based on memory and weak words.
