Ride the Wave of Language

Not released yet — sssurf arrives on the App Store and Google Play in late August 2026.
What is sssurf
A language app built out of real short-form video
Forget textbooks and lectures. sssurf turns short-form videos filmed by real people around the world into your learning material — jokes cracked at a drive-thru, chats between friends, the unfiltered expressions people actually use. Catch the wave, and the language sticks.
01Learn from real everyday videos
Short-form videos uploaded by users worldwide show you how the language is actually spoken, not how a textbook says it should be.
02Dual subtitles, instant lookup
Watch with the original and translated subtitles at once, and tap any word to check its meaning, part of speech, and real-world examples.
03Deep-dive sentence learning
Break a sentence down word by word, with the core expressions and key grammar points pinpointed for you.
04Save and review
Keep the words and expressions you like in a personal study list, and come back to review them as often as you need.
05More than 10 languages
Not just English — learn a wide range of languages through the same interactive method.
