LangUp: AI and ML based Language Learning Tool

Immersive language learning through the content you already read.

LangUp blends your target language into any English passage using a technique called code-switching — the same mechanism linguists observe in natural bilingual environments. Rather than drilling flashcards in isolation, you encounter new words inside context you care about, which is where retention actually happens.
