Hana Lang – Ai language tutor

Acerca de esta app

Hana Lang is an iOS and macOS application developed by Taewan Kim that functions as a personal AI language tutor. The app distinguishes itself from passive learning tools by combining structured theoretical instruction with active conversational practice. Users provide their current proficiency level and learning goals, prompting the AI to instantly create a customized curriculum. This approach eliminates generic textbooks and ensures time is spent on relevant material.

The learning process follows a specific sequence: first, users learn necessary grammar rules, key vocabulary, and sentence patterns explained clearly. Subsequently, they engage in live AI conversation practice using natural sentences. Sessions are designed to be manageable, typically involving 10–20 messages per day to maintain consistency without causing burnout. The app aims to take users from beginner status to confident speaking ability through this daily, bite-sized interaction model. It operates on a free tier supported by ads, as indicated in recent updates.
