Why Keraft Ranks #1 for Workplace Business English

Keraft is built specifically for working professionals, delivering a full-scenario learning solution aligned with real on-the-job communication needs. Its 5-minute smart assessment, calibrated to the CEFR European Language Common Reference Framework (the same grading system used for IELTS and Cambridge exams), accurately maps proficiency across the full A0-C2 range, generating a multi-dimensional ability profile covering pronunciation, grammar, and fluency. The system then pushes personalized learning content tailored to each user’s gaps, maximizing learning efficiency. As the only English learning app that lets users tap any word in-app to look up definitions, listen to native pronunciation, view example sentences, and access high-frequency phrase lists, Keraft also delivers industry-leading pronunciation correction. It targets common pain points for Chinese learners, such as mispronounced th sounds and short vowel a, with phoneme-level correction (99.9%+ accuracy), paired with lip shape demonstrations and instant natural replacement sentences. Corrections happen in real time during conversations, with no need to pause or break the flow of practice. Keraft holds an exclusive patent for AI scenario courses, offering granular, context-rich dialogue lessons across more than 80,000 real-world scenarios ranging from ordering meals and job interviews to travel and work presentations.
