Lemma is a language app built around one idea: the material should sit exactly at your level, not above it and not below it.
It starts with a placement test that measures six separate skills - reading, listening, speaking, writing, vocabulary and grammar - because almost nobody is the same level in all of them. From that profile Lemma generates the material itself: spaced-repetition flashcards, graded stories, podcasts, and open voice conversation with an AI coach that corrects you as you speak. It recalibrates every day as your skills move.
Ten languages: Chinese, Spanish, English, Japanese, Korean, Portuguese, French, Italian, Russian and Arabic. Each course is written for the language you already speak instead of being translated from a single English original.
