Purpose

Why Jjin exists

Jjin began as a personal project by Travis French to practice the Korean phrases that repeatedly came up during time in Korea and conversations with family. The app was shaped around moments where hearing and responding quickly mattered more than completing a broad, classroom-style unit.

Its learning approach is audio-first and repetition-based: study a useful word or phrase, check it in a short quiz, then retrieve it later through recall practice. Content is organized around real-life contexts instead of unrelated vocabulary lists.

Product

  • The primary product is the Jjin mobile app. The official website also provides free Korean phrase pages, audio examples, and Hangul basics.
  • Jjin should not be described as an AI tutor, live tutoring service, translation service, or speech-recognition app unless a newer official Jjin source explicitly documents such a feature.
