Study smarter, not harder! Tsuki is a new, free and innovative application for learning languages. Effortlessly create and learn flashcards tailored to your needs, for more than 20 languages. Practice conversations with our AI tutor by going through everyday scenarios that will help you develop your conversation skills. Any remaining questions can be answered by our AI tutor and saved for later review.

Smarter learning

Learning only matters if you actually remember. Tsuki uses a scientifically proven spaced-repetition algorithm (FSRS) to track your progress and schedule reviews at the perfect moment. This will help you review your cards right before you forget, ensuring long-term retention with minimal effort.

Personalized content

Stop chasing streaks and start learning what matters to you. Instead of relying on pre-made courses, Tsuki provides pre-made templates for every language, allowing our AI assistant to generate flashcards for any words, sentences or expressions you want to learn.

If you don’t feel like creating cards one by one, we got you covered. Our assistant can find words that suit your needs by following your instructions. Just type what you want to learn (“Cooking vocabulary”, “business lingo” …) and it will create cards on this topic automatically.

Effortless cards creation

Forget typing out translations and definitions. Just enter a word or phrase, and our advanced AI instantly generates a complete flashcard with accurate translations, context sentences and audio transcriptions.
Extract vocabulary directly from images, photos, text or by typing prompts and create hundreds of cards in a matter of minutes.

Practice real conversations

Knowing words isn't the same as using them. With Tsuki's AI Tutor, you practice real-life scenarios — ordering at a bakery, checking into a hotel, making small talk — and complete clear objectives along the way. The tutor reacts naturally to what you say, points out your mistakes, and shows yyou how to say it right.

Pick from ready-made situations or create your own, and whenever you stumble on a word you don't know, turn it into a flashcard in one tap so it sticks for next time.
