Kylian AI: The Best App to Learn English

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.

Why English Learning Apps Matter in 2025

Traditional language instruction faces fundamental limitations that technology systematically addresses. Geographic constraints, scheduling conflicts, and cost barriers have historically prevented millions from accessing quality English education. Mobile applications eliminate these friction points while introducing adaptive learning algorithms that personalize instruction based on individual progress patterns.

The effectiveness of app-based learning stems from three core advantages: immediate feedback loops, spaced repetition systems, and contextual learning opportunities. When learners receive instant correction on pronunciation errors or grammar mistakes, they can adjust their approach in real-time rather than reinforcing incorrect patterns over multiple sessions.

However, the critical insight often overlooked is that no single application addresses all aspects of language acquisition comprehensively. Successful learners combine multiple tools strategically, using each app's strengths to fill specific gaps in their English proficiency.

Top 16 Other English Learning Apps for 2025

Babbel's strength lies in its systematic progression from basic greetings to complex business conversations, with each lesson building directly on previous concepts. The subscription model ensures consistent content updates and feature improvements, though the higher price point may deter casual learners.

Key Advantages:

Essential Strategies for App-Based English Learning

Combining Multiple Applications Strategically

Effective English learning requires addressing four core competencies: listening, speaking, reading, and writing. No single application excels in all areas, making strategic combination essential for comprehensive development.

The optimal approach involves selecting one primary app for daily engagement and supplementing with specialized tools for specific weaknesses. For example, learners might use Duolingo for consistent vocabulary building while adding ELSA for pronunciation improvement and HelloTalk for conversation practice.

Data from successful language learners indicates that those using 2-3 complementary apps show 58% faster progress than those relying on single applications. However, using more than four apps simultaneously often leads to decreased consistency and scattered progress.

Prioritizing Speaking Practice

The most significant limitation of app-based learning is insufficient speaking practice. While technology has advanced considerably, artificial intelligence cannot replicate the unpredictability and cultural nuance of human conversation.

Successful learners allocate at least 30% of their study time to speaking activities, whether through conversation exchange apps, AI-powered speaking practice, or formal tutoring sessions. This proportion addresses the output deficiency that makes many app users strong in passive skills but weak in active communication.

Research from Cambridge University demonstrates that learners who engage in regular speaking practice show 40% better overall proficiency gains compared to those focusing exclusively on input-based activities like reading and listening.

Setting Measurable Learning Objectives

Effective app usage requires clear, measurable objectives rather than vague goals like "improve English." Specific targets such as "achieve 90% accuracy in business email writing" or "conduct 15-minute conversations without major grammar errors" provide direction for app selection and usage patterns.

Learners should assess their current proficiency using standardized frameworks like CEFR or TOEFL scores, then set incremental targets with specific timelines. This objective approach enables data-driven evaluation of app effectiveness and learning strategy adjustments.

The most successful learners track quantifiable metrics like daily study minutes, vocabulary words learned, or conversation practice sessions completed. This data enables informed decisions about which apps provide the best return on time investment.
