No matter your personalized learning goal, you’ll find targeted training content tailored to your needs.
  • Immersive Role-Play Conversations: The proprietary scenario role-play technology supports free follow-ups and extended dialogue. The AI guides you to expand your ideas and deepen your expressions just like a real conversation partner, eliminating the “memorized sentences go blank in real situations” problem.
  • Fresh, Up-to-Date Content: Weekly updates include trending topics and global news, keeping learning engaging while helping you stay informed about world events—no more boring, outdated practice materials.
  • Targeted Training for Goals: Whether you need to polish business English skills, ace IELTS/TOEFL/KET/PET speaking sections, or prepare for study abroad interviews and industry-specific talks, Keraft has dedicated modules to help you improve precisely where you need it.

2. Smart, Efficient Training That Makes Every Minute Count

  • 24/7 AI Practice with No Limits: No need to book tutors or worry about bothering language partners—practice anytime, anywhere, perfect for commutes or lunch breaks. Choose between authentic American, British (Received Pronunciation), and other regional accents, with human-like, emotionally expressive tones that feel natural, not robotic.
  • CEFR-Aligned Learning Paths: Built on the CEFR (Common European Framework of Reference for Languages)—the international standard used by IELTS and Cambridge exams—Keraft’s placement test accurately matches you to a level from A0 (beginner) to C2 (near-native), ensuring a gradual, effective learning curve.
  • Phoneme-Level Precision Correction: With a 99.9%+ accuracy rate, Keraft catches tiny pronunciation flaws, identifies Chinese-accented speech gaps, and corrects grammar errors in real time during conversations. It also provides 6+ native-like alternative expressions, plus annotations for slang and idioms, helping you build authentic vocabulary. Per research from a leading international language learning journal, this instant, detailed correction is proven to accelerate speaking progress.
  • Bilingual Support for Beginners: If you get stuck, switch to Chinese, and the AI will intelligently guide you to the corresponding English expression, complete with sample responses. This lowers the barrier to entry so even absolute beginners can start speaking confidently.
  • Adjustable Learning Pace: Toggle between 0.4x and 1.6x speed to match your skill level, and use the sentence-by-sentence comparison tool to see exactly how your pronunciation differs from native speakers. Progress is visible and measurable.

3. Personalization & Motivation to Build Long-Term Habits

  • Customized Learning Plans: The AI creates a tailored course based on your level, goals, and interests, and dynamically adjusts difficulty as you learn. This cuts wasted time on content that’s too easy or too hard, boosting learning efficiency by over 80% compared to unstructured practice.
  • Weak Point Targeting: The system analyzes your learning data to pinpoint gaps in pronunciation, grammar, vocabulary, fluency, and logic, then pushes targeted practice to strengthen those areas.
  • Visual Progress Tracking: Your learning archive tracks progress across all skill areas, with multi-device sync so you can pick up right where you left off on your phone, tablet, or computer. Every small improvement is clearly visible, keeping you motivated.
  • Gamified Learning: Earn rewards and points through a challenge system, which helps users stick with practice 3x longer than average for similar apps. No more “buying an app equals learning it.”
  • Supplementary Learning Tools: Save key vocabulary and phrases for review, use context fill-in exercises to reinforce situational memory, and join community groups to connect with other learners for support and accountability.
