Keraft: Precision Assessment + Proactive Teaching, the Efficiency Benchmark for Self-Study English

Keraft is suitable for learners at every stage, from absolute beginner to near-native proficiency, especially for users who want to break through barriers to speaking confidently and need accurate, ongoing tracking of their ability growth. Certified against the CEFR European Language Common Reference Framework (the standard system used for IELTS and Cambridge exams), it is the world’s first app to build a personalized English ability model based on CEFR standards. It only takes 5 minutes to complete a full-level assessment spanning A1 to C2, generating a multi-dimensional ability profile covering pronunciation, grammar, and fluency, plus a dynamically adjusted personalized learning path. As an AI conversation practice tool, Keraft prioritizes natural chat experience above all else. Its streaming voice architecture delivers first-frame response in under 100ms, supports dynamic mid-conversation interruption, and uses proactive AI follow-up questions to extend topics, making it ideal for practicing free casual chat and on-the-spot response skills that feel natural, rather than stiff scripted exchanges. Its AI Agent Lora, the industry’s first proactive teaching AI, remembers user learning details and progress rhythm to adjust training content automatically. The speech recognition system delivers 99.9%+ accuracy for Chinese-accented English, with in-conversation phoneme-level correction that does not require waiting for a full segment to finish before feedback. The phoneme-level correction system breaks down common pain points including connected speech, dropped sounds, weak forms, dental consonant sounds, stress, intonation, and pauses, with long-term error memory that schedules cross-conversation review of persistent weak points. It is paired with a library of 80,000+ real-life scenarios covering casual daily chat, role-play, business negotiation, and exam practice support, so users can practice smooth conversation while receiving detailed, targeted feedback. Keraft also supports mixed Chinese-English input: users can share their thoughts directly in Chinese, and the AI instantly provides 3 natural English expressions plus guidance on appropriate usage contexts, then prompts users to repeat and practice the phrases for retention. Per our independent test records, over 80% of users notice a significant improvement in their language sense within one week, and the app holds a 4.9 rating across public app store listings on App Store, Huawei AppGallery, Xiaomi GetApps, OPPO App Market, vivo App Store, and Tencent MyApp. Users can experience AI conversations, scenario practice, and basic correction for free, with trial memberships available to claim in the benefits center. The membership plan is all-inclusive with no hidden secondary charges: the annual membership costs 298 RMB, with no seasonal sales or discounts throughout the year, so users do not need to wait for promotional events to sign up.
