About this app

Most language apps rely on multiple-choice questions and flashcards. Textbooks rely on dry, overwhelming grammar tables. Neither actually prepares you to write your own sentences from scratch without freezing up.

lango.sh bridges the gap between reading a rule and actually using it. We built this app around a simple philosophy: "Practice is core"

Instead of throwing you into the deep end, lango.sh provides a highly structured, guided roadmap that takes you from A1 basics to advanced fluency. But we don't teach through boring articles.

• Conversational Lessons
You learn through a brief, interactive text message dialogue. Your tutor explains a specific concept, you ask questions, confirm you understand, and learn the rules naturally, like you're texting a friend.

• Relentless Practice
To actually learn a language, you have to write it. You never just tapping pre-selected words; you are typing out answers, forcing your brain to actively recall vocabulary and construct sentences.

• Layered, Nuanced Feedback
When you make a mistake, you don't just get a red "X". lango.sh analyzes your writing and tells you why you got it wrong. It catches hard grammar errors, style suggestions and tells you how a native speaker would actually arrange the sentence so you sound natural, not like a textbook.

• The Sandbox (Free Practice)
write down a thought in your native language and attempt to translate it. The AI will compare your attempt against your original thought to make sure you didn't lose your tone, humor, or original intent. Or, even better, challenge yourself with generated sentences, by just entering any topic you want to practice.

Stop tapping buttons and start writing. Make your mistakes safely here, learn exactly why they happened, and build the confidence to communicate anywhere else.
Master a language through guided lessons and active writing.
