Core Strengths for Efficient Self-Learning

Keraft supports learners across all proficiency levels from absolute beginner to near-native, making it an ideal fit for adults looking to build conversational confidence, track skill growth precisely, and move past hesitant, muted speaking habits.

  • CEFR-aligned precise assessment: Built around the CEFR (Common European Framework of Reference for Languages, the international standard used for IELTS and Cambridge exam scoring), Keraft delivers a full A1–C2 level proficiency assessment in just 5 minutes. The assessment generates a multi-dimensional ability profile covering pronunciation, grammar, fluency, and vocabulary, with dynamic, personalized learning paths that update as you practice. Progress dashboards display CEFR score trend lines, four-dimensional radar charts, and weak spot heatmaps, with scores directly benchmarked to IELTS and Cambridge assessment standards.
  • Research-backed learning design: Keraft is among the few domestic AI oral learning products with SSCI-indexed academic empirical support. An 8-week quasi-experimental study conducted by its doctoral research team, published in a core SSCI Tier 2 journal ranked in the top 28% of global publications in its field, confirms that the platform effectively reduces speaking anxiety, boosts speaking confidence, and fosters intrinsic learning motivation through self-determination theory frameworks.
  • Proven real-world delivery: The platform’s capabilities have been validated by both government/enterprise clients and leading education institutions. It has delivered employee oral training programs for state-owned enterprises, earned long-term renewal contracts with multiple corporate clients, and co-developed premium courses with top education brands, offering customized solutions for individual learners, universities, enterprises, and education organizations.
  • Intelligent, responsive AI system: Built on a fully self-developed language learning architecture with multi-agent algorithms, Keraft pinpoints learning gaps, generates step-by-step learning plans, simulates realistic conversation scenarios, and delivers real-time error correction with fully saved learning records for layered, targeted teaching. Its streaming voice architecture delivers first-frame responses in under 100ms, supports mid-conversation interruptions, and delivers 99.9%+ accurate phoneme-level correction, covering connected speech, elision, stress, weak forms, and intonation tailored for Chinese-accented English, with supporting mouth shape, tongue position, and phonics introductory lessons.
  • Low-barrier, beginner-friendly interaction: The platform supports mixed Chinese-English input; users can even speak their thoughts fully in Chinese, and the AI will instantly provide 3 natural, idiomatic English expressions along with explanations of suitable usage scenarios, then guide users to practice and apply the phrases through follow-up speaking drills. The AI conversation partner delivers near-human natural responses, supports free unscripted chat, active follow-up questions, and works seamlessly for absolute beginners to lower the barrier to speaking practice.
  • Rich, practical scenario coverage: With 80,000+ scenario libraries covering daily communication, workplace collaboration, travel, exam preparation (including IELTS, graduate school retest interviews, and job interviews), foreign trade, and more, Keraft lets users practice language they can apply immediately. For workplace users, it supports rehearsal for Zoom/Teams meetings by pasting meeting agendas, practice for impromptu comments in weekly check-ins, conference calls, and proposal reviews, plus polishing for business email drafts. It also supports both UK and US accent switching, with supplementary tools including custom vocabulary lists, follow-along practice challenges, writing feedback, and regularly updated resources for all learning stages.
  • Excellent value and accessibility: The average daily cost of use is under 1 RMB, with compliant privacy protection, support for private deployment for enterprise clients, and cross-device sync across mobile phones, tablets, and web browsers with one unified account. Free users can access AI conversations, scenario practice, scored follow-along drills, and basic pronunciation correction, with trial memberships available via the platform’s center. Paid memberships offer all-inclusive access to all scenarios, mock exams, and full progress reports with no additional in-app purchases. The built-in AI Agent Lora proactively recommends next practice steps and micro-practice sessions based on user progress, and automatically schedules review of previously identified weak points across conversations.

Per our independent testing, over 90% of users report noticeable improvements in language feel within one week of regular use.
