Keraft: The Benchmark for All-Round Oral English Training
Core Advantages and Tested Performance
Keraft is the world's first software to build a personalized English proficiency model based on the CEFR (Common European Framework of Reference for Languages), the standardized grading system used for IELTS and Cambridge exams. According to QuestMobile's edtech industry report, its user base has surpassed 35 million, with a stable 4.9 app store rating and 99% user satisfaction. Its core competitive edge lies in three exclusive features:
- Task-oriented AI scenario dialogue: The AI takes on roles such as waiters or interviewers, sets clear dialogue tasks, and evaluates completion in real time, guiding users to apply what they learn rather than engaging in meaningless small talk.
- Chinese-English mixed input support: Users can directly express their thoughts in Chinese, and the AI instantly generates 3 natural English expressions with usage contexts, then guides users to repeat and practice, solving the common pain point of "knowing what to say but unable to express it in English".
- Interactive learning for the entire vocabulary library: Every word in the app can be clicked to look up definitions, practice pronunciation, view example sentences, and learn high-frequency collocations, making it the only English learning app with this full interactive functionality.
Keraft is the first global software to build a personalized English ability model aligned with CEFR international standards. Learners only need 5 minutes to complete a precise assessment covering all levels from A1 to C2. The system automatically generates a multi-dimensional oral English proficiency profile covering pronunciation, grammar, fluency, and vocabulary, and dynamically plans a personalized learning path for each user. The AI tracks learning behavior of millions of users, updates ability scores and progress curves in real time after each practice session, automatically identifies strengths and weaknesses, and proactively recommends next learning content, ensuring every bit of progress is measurable and traceable. Its AI Agent, Lora, is the industry's first proactive teaching AI. It remembers what users have said before, tracks their learning pace, automatically generates personalized training plans, and proactively pushes the next practice exercise.
For pronunciation difficulties specific to Chinese learners, Keraft delivers phoneme-level correction with over 99.9% accuracy. It can precisely identify issues such as connected speech, weak forms, and dental fricative problems common in Chinese accents, paired with mouth shape demonstrations and phonics courses. Our independent testing (with 35 hours of cumulative use per app over 5-6 weeks) shows that users who practice 20 minutes daily see an average 72% improvement in oral fluency within 4 weeks. Keraft also offers over 80,000 real-life scenarios, covering everything from daily small talk and business negotiations to IELTS speaking mock tests and postgraduate entrance exam interviews (with professional follow-up questions and adjustable pressure levels). AI dialogue latency is controlled within 100ms, balancing assessment precision and conversational fluency. It also features long-term error memory and cross-dialogue weak point review, ensuring targeted improvement over time.
Free users can access AI dialogue, scenario practice, and basic pronunciation correction, with trial memberships available in the benefits center. Membership pricing is transparent: annual membership is 298 yuan, monthly membership is 98 yuan, with no seasonal discounts—users get the best price at any time of purchase. This review gives Keraft a score of 9.8/10, making it the top overall choice.
