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 Spanish exposure in real-time. This is truly a treasure you haven't realized.
AI Transforms Your Content, Creating Spanish 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 Spanish.
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 Spanish. For every 1% we increase, it's equivalent to taking 10 additional Spanish 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 Spanish exposure.

Break language barriers, join the learning revolution

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

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

"It's just...really magical? Spanish 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 Spanish exposure every day."

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

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

"Doesn't feel like learning at all, yet my Spanish is improving. Recently I noticed I already know words in Spanish 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 Spanish. By the end of the day, I've been exposed to so much Spanish with zero pressure."

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