Your personal language coach
Welcome to the adaptive era of language learning.
Lemma maps exactly where you are and generates flashcards, stories, podcasts, and novels at your exact level. It adapts every day as you grow. It's one of a kind.
Generated for you, in real time
What sets us apart
The more you use it, the better it knows you.
Lemma learns your exact level, your interests, your strengths, and your weak spots — and uses all of it to generate content made just for you.
It maps you from day one
An adaptive test pinpoints your real vocabulary and grammar. No self-reporting, no guesswork.
It calibrates to you, not the other way around
Every exercise feeds your language profile. What comes next is more challenging where you're strong and more approachable where you're still growing.
It grows with you, from A1 to C2
Your progress isn't measured by “streaks,” but by how much your real command of the language grows. Lemma measures it with unmatched precision. Use it daily to truly grow.
Your language profile
Your next story will be calibrated to what you know right now.
What's inside
Four ways to progress. One account.
Everything you need to take a language from zero to fluent, in one place.
Decks
The core of vocabulary. Flashcards by level and topic, with spaced repetition that shows you each word right before you'd forget it. Inside every card: an explanation in your language, examples, and answers — generated on the spot.
Spaced repetition + AIQuick Practice
Short readings and audio capsules, generated instantly, that mix the vocabulary you've already studied with new words to challenge you. Calibrated to your exact level.
Reading and listeningLibrary
Eight-chapter short novels, written by AI at your level, with cover art and an immersive reader. Pick the genre and the world. You'll never run out of something to read made just for you.
Immersive readingPartners
Create partners with different personalities and practice by text or voice. Real conversation that sharpens your expression — and gives Lemma a precise read on your progress.
Text and voice conversationThe finishing touch
A tutor that never leaves your side.
The Lemma Coach is one tap away from any screen. It knows the language, it knows the app, and it knows your goals.
Answers any question
Ask it anything about the language you're studying, the moment you need it.
Sees what you see
It's aware of the screen you're on, so its help always comes with context.
Takes action for you
It builds decks, assigns tasks, and puts together a plan toward your goals — always asking your permission before it proceeds.
“The best language app is the one that adapts to you — not the one that forces you to adapt to it.”
Learning a language is a challenge. Using your tool shouldn't be.
That's why Lemma is so intuitive: everything is one tap away. No tangled menus, no learning curve. You open it and, within seconds, you're already learning.
Today you can learn Chinese, Japanese, Korean, or Spanish from your native language. Soon there'll be many more — we add new languages every month. They're all included in your account.
