About this extension
Korean Sensim helps you learn Korean naturally while browsing the internet.

Instead of interrupting your day with flashcards, drills, or grammar exercises, Sensim gradually replaces common English words on webpages with Korean words while you browse normally. The experience is designed to feel effortless, immersive, and easy to maintain long term.

Only a few words appear at first, making learning intuitive and low stress. As your vocabulary grows, Sensim slowly increases the number and complexity of Korean words through repetition and context.

Features:

Learn Korean passively while browsing the web
Build vocabulary naturally through repeated exposure
No flashcards, streaks, or stressful lessons
Designed for effortless daily immersion
Works on websites you already visit
Helps Korean words become instinctive over time
Lightweight and distraction-free experience

Korean Sensim is ideal for beginners, travelers, students, K-drama fans, language enthusiasts, and anyone who wants to absorb Korean naturally throughout the day.
