RiesIs Different
We don't offer any language learning courses
Integrated Into Every Article and Video You Watch
We explore the content scenarios you're viewing and create appropriate Korean exposure in real-time. This is truly a treasure you haven't realized.
AI Transforms Your Content, Creating Korean Exposure
AI analyzes your content and selects appropriate transformation methods, from words to phrases, from short sentences to long sentences, continuously creating extensive exposure, letting you unconsciously acquire Korean.
Especially the Large Volume of English Content You're Viewing
You read over 20,000 words of English content daily, but less than 1% exposes you to Korean. For every 1% we increase, it's equivalent to taking 10 additional Korean classes.
Pressure Control That Understands You
AI will adjust exposure difficulty and transformation methods based on your language map, ensuring you can both easily understand and gradually improve, creating 100x pressure-free Korean exposure.

Break language barriers, join the learning revolution

"Never thought browsing the web could teach me Korean! Seeing Korean words in English news felt strange at first, but now it feels incredibly natural with zero learning pressure..."

"Korean always made me anxious - memorizing vocabulary was painful. This extension is completely different. It integrates Korean into content I actually enjoy without rote memorization. With enough exposure, it just clicks!"

"It's just...really magical? Korean words and phrases appear when I'm reading novels or browsing social media. At first I thought it was a bug, then realized this IS the learning method! I'm unconsciously increasing my Korean exposure every day."

"I used to force myself to watch Korean videos but couldn't stick with it. Now it's completely different - I learn Korean vocabulary while watching English videos. I remember words without even trying!"

"As a programmer, Korean documentation was such a headache. Ries changed my experience by gradually replacing familiar English content with Korean. The progressive approach removed anxiety and dramatically increased my exposure."

"Doesn't feel like learning at all, yet my Korean is improving. Recently I noticed I already know words in Korean articles that I used to look up...all accumulated from daily exposure."

"Love that I don't need to deliberately study. Just normal web browsing, with AI occasionally replacing words with Korean. By the end of the day, I've been exposed to so much Korean with zero pressure."

"My child always resisted learning Korean. Since using this, I discovered he's learning vocabulary while watching YouTube! No more forcing him to take classes - natural exposure means faster improvement."

"Traditional Korean learning was painful! Ries doesn't require extra time - it transforms my regular web browsing to increase Korean exposure. Perfect for lazy people like me, haha! Improvement without even noticing."
