If you’ve ever struggled to move beyond memorized phrases to real, confident English conversation, Keraft is the AI-powered solution designed to bridge that gap. Built for learners at every level, from absolute beginners aiming for basic communication to advanced users targeting native-like proficiency, this app turns practice into tangible progress with tailored, real-world-focused features.

Immersive Role-Play for Real-World Fluency

Keraft’s core strength lies in its 80,000+ realistic role-play scenarios, covering every situation you might encounter: nailing a job interview, ordering coffee abroad, discussing work projects in a meeting, or even navigating a doctor’s appointment. Unlike generic chat tools, Keraft’s AI takes on specific roles—from a strict hiring manager to a friendly barista—and guides you through structured, task-based conversations. You can even customize scenarios in 30 seconds by describing your exact learning goal, ensuring every practice session aligns with your personal needs. Best of all, you can practice at your own pace, no awkwardness or judgment involved.

Precision Feedback That Drives Improvement

Forget vague corrections: Keraft delivers 99.9% accurate phoneme-level pronunciation feedback, breaking down every sound (/p/, /æ/, /θ/, and more) to pinpoint issues like mispronounced rolled Rs, missing weak sounds, or accent quirks. It doesn’t just tell you you’re wrong—it shows you how to fix it, with mouth and tongue position guides and targeted shadowing exercises.

Beyond pronunciation, Keraft catches grammar mistakes and awkward phrasing in real time, offering natural alternatives with clear explanations. For example, it’ll correct "I very like it" to "I really like it" and explain why the latter sounds more native. And if you’re stuck for words, you can even speak your thoughts in Chinese, and Keraft will instantly provide 3 natural English phrases, plus context on when to use each one, then guide you to practice using them.

CEFR-Aligned Learning: Measurable, Personalized Progress

As the world’s first app to build individual English proficiency models based on the CEFR international standard, Keraft takes the guesswork out of learning. Start with a 5-minute, precise CEFR assessment (covering pronunciation, grammar, fluency, and vocabulary) to get a clear snapshot of your current level, from A1 (beginner) to C2 (mastery). The AI then creates a dynamic, personalized learning path that adapts as you progress.

According to the EF English Proficiency Index, speaking is the weakest skill for most English learners globally. Keraft addresses this by tracking the learning behaviors of over 35 million users, updating your proficiency score and progress curve after every session. It identifies your weak spots—whether it’s business formal vocabulary or conversational fluency—and recommends targeted exercises to help you improve faster.

Keraft grows with you, no matter where you are on your English journey:

  • Beginners: Start with foundational phonics and basic greetings, working up to simple daily conversations.
