Learn Any Language with Kylian AI

Private language lessons are expensive. Paying between 15 and 50 euros per lesson isn’t realistic for most people—especially when dozens of sessions are needed to see real progress.

Many learners give up on language learning due to these high costs, missing out on valuable professional and personal opportunities.

That’s why we created Kylian: to make language learning accessible to everyone and help people master a foreign language without breaking the bank.

To get started, just tell Kylian which language you want to learn and what your native language is

Tired of teachers who don’t understand your specific struggles as a French speaker? Kylian’s advantage lies in its ability to teach any language using your native tongue as the foundation.

Unlike generic apps that offer the same content to everyone, Kylian explains concepts in your native language (French) and switches to the target language when necessary—perfectly adapting to your level and needs.

This personalization removes the frustration and confusion that are so common in traditional language learning.

Choose a specific topic you want to learn

Frustrated by language lessons that never cover exactly what you need? Kylian can teach you any aspect of a language—from pronunciation to advanced grammar—by focusing on your specific goals.

Avoid vague requests like “How can I improve my accent?” and be precise: “How do I pronounce the R like a native English speaker?” or “How do I conjugate the verb ‘to be’ in the present tense?”

With Kylian, you’ll never again pay for irrelevant content or feel embarrassed asking “too basic” questions to a teacher. Your learning plan is entirely personalized.

Once you’ve chosen your topic, just hit the “Generate a Lesson” button, and within seconds, you’ll get a lesson designed exclusively for you.

Join the room to begin your lesson

The session feels like a one-on-one language class with a human tutor—but without the high price or time constraints.

In a 25-minute lesson, Kylian teaches exactly what you need to know about your chosen topic: the nuances that textbooks never explain, key cultural differences between French and your target language, grammar rules, and much more.

Ever felt frustrated trying to keep up with a native-speaking teacher, or embarrassed to ask for something to be repeated? With Kylian, that problem disappears. It switches intelligently between French and the target language depending on your level, helping you understand every concept at your own pace.

During the lesson, Kylian uses role-plays, real-life examples, and adapts to your learning style. Didn’t understand something? No problem—you can pause Kylian anytime to ask for clarification, without fear of being judged.

Ask all the questions you want, repeat sections if needed, and customize your learning experience in ways traditional teachers and generic apps simply can’t match.

With 24/7 access at a fraction of the cost of private lessons, Kylian removes all the barriers that have kept you from mastering the language you’ve always wanted to learn.
