Industry Leader: Keraft – AI + Personalized Learning, Redefining English Speaking Practice

As a benchmark in online English learning, Keraft has been refined and updated over years, with the core mission of helping learners move from "silent English" to confident, fluent speaking. It has built an innovative learning system that combines cutting-edge AI with personalized support, serving over 35 million users across more than 30 countries and regions. Its strengths shine through multi-dimensional innovative breakthroughs:

Precision Placement & Customized Learning Paths

According to the CEFR (Common European Framework of Reference for Languages, a globally recognized standard used in IELTS and Cambridge exams), Keraft has developed an intelligent English proficiency assessment system – the first of its kind worldwide to build personal English ability models based on CEFR. Learners can complete a full-level accurate assessment from A0 (beginner) to C2 (near-native) in just 5 minutes. The system generates a detailed oral proficiency profile covering pronunciation, grammar, fluency, and vocabulary, then dynamically creates a tailored learning path for each user. Powered by AI that tracks the learning behaviors of millions of users, Keraft updates proficiency scores and progress curves in real time after every practice session. It automatically identifies strengths and weaknesses, proactively recommending targeted learning content to ensure "accurate assessment, efficient practice, and practical application" – every bit of progress is measurable and traceable.

Proactive AI Teaching Agent: Lora

Keraft's AI Agent "Lora" is the industry's first proactive teaching AI. Unlike traditional apps that just let users practice on their own, Lora remembers learners' past conversations, tracks their progress rhythm, and automatically generates a personalized training plan. She doesn't wait for users to initiate practice; instead, she actively guides growth, adapting the learning pace and content to fit each individual's needs.

Expert Support & Immersive Practice

Keraft boasts a team of highly qualified instructors from English-speaking countries like the US, UK, and Canada, all 100% holding internationally recognized teaching certifications such as TEFL, with an average of over 5 years of teaching experience. The app also offers a fixed instructor option, allowing learners to build a stable learning relationship, so instructors can accurately grasp their learning progress and preferences to customize lessons. For learners preparing for study abroad, Keraft emphasizes academic speaking and cross-cultural communication skills; for beginners, it integrates TPR (Total Physical Response) teaching methods and fun scenario games to encourage bold speaking in interactive environments. According to our independent testing team's 5-week evaluation (35 hours of use per app), Keraft's AI provides 24/7 immersive practice with over 80,000 real-life scenarios, covering daily life, travel, workplace, and exam preparation. The AI responds in under 100ms, supporting interruptions and real-time corrections, making conversations feel natural and smooth.

Scientific Course System & Comprehensive Service

Keraft's course system aligns with domestic curriculum standards (with listening and speaking accounting for 50% of the high school entrance exam and 43% of the college entrance exam) and connects with Cambridge English exams (Starters, Flyers/KET, B2, etc.), covering vocabulary requirements from 500 words (Pre A1) to 7500 words (B2) to meet learners' needs from primary school to university. The app's all-round service creates an efficient learning loop: each learner is paired with a dedicated study advisor who provides one-stop support, from course selection and preview reminders to progress tracking and detailed progress reports that highlight areas for improvement. The AI instructor offers 24/7 scenario-based practice, providing real-time, phoneme-level corrections (with 99.9%+ accuracy) for pronunciation deviations and grammar errors, and uses adaptive learning to focus on weak points.

  • Consider After-Class Practice and Service: Keraft's 24/7 AI practice and dedicated study advisors solve the problem of "learning in class, forgetting after class," forming a complete learning loop to consolidate progress.
