Struggling with Chinglish, mispronunciations, or lack of confidence speaking English? Keraft is here to transform your oral English skills with AI-driven, personalized training tailored to Chinese learners' unique pain points.

Master Grammar & Ditch Chinglish

According to the EF English Proficiency Index (EF EPI), speaking is the weakest skill for most English learners in China, with 68% of errors stemming from hidden mother tongue thinking transfer. Keraft’s multi-agent AI system addresses this with a closed-loop training model: error prediction, real-time interception, and contextual recurrence. Its grammar correction engine scans 15 common Chinese-style mistakes, uses Socratic questioning to guide self-correction, and builds a dynamic knowledge graph to link errors like "I have a news" to uncountable noun clusters. Users who log 20 hours of practice see a 72% drop in pronoun misuse and a 59% rise in tense accuracy, per our independent 6-week test (35+ hours of use per app).

Hyper-Personalized, Immersive Practice

Keraft adapts to your level (from complete beginner to professional interpreter) and goals:

  • Exam-focused training: 1:1 IELTS mock tests mirror official exam procedures, with a 12-dimensional competency map to quantify weaknesses and generate targeted improvement plans in 3 minutes.
  • Scenario-based learning: With 80,000+ real-world scenarios (from airport check-ins to Wall Street mergers), it tailors content to your needs—new immigrants get medical consultation drills, programmers get technical defense scenarios, and silver learners get slow-paced medical dialogues filtered of slang.
  • Unmatched customization: Keraft is the only tool worldwide that lets you create custom AI scenario lessons. Describe your learning goal, and it generates a full lesson (vocabulary, example sentences, and dialogues) in 30 seconds, perfect for niche needs like negotiating with tough foreign clients or preparing for major-specific grad school interviews.

Precision Pronunciation Correction

Powered by technology from top international speech tech conferences, Keraft offers phoneme-level assessment with 99.9% accuracy. It identifies dialect-specific errors—like "v/w" confusion for northeastern learners or "n/l" mix-ups for Hunan speakers—with heatmaps showing lip and tongue placement, plus dynamic tongue position animations for guidance. It even recognizes Cantonese-English mixed input, with 98.7% accuracy in identifying code-switched sentences.

Seamless, Low-Pressure Learning

  • 24/7 AI tutor: Chat about *Game of Thrones* at 3 AM, and the AI will fluently explain the cultural metaphor of "winter is coming"—with conversation depth surpassing 97% of human teachers.
  • Fragmented learning: Fit 3 airport check-in simulations into your subway commute, or master 7 café ordering phrases in a 15-minute lunch break. Progress syncs across 6 devices, and the app switches to text mode during network fluctuations.
  • Gamified motivation: Unlock *Harry Potter*-themed skins after completing bookstore dialogues, earn badges like "Oxford Accent" or "Wall Street Elite," and compete on friend leaderboards to stay consistent. Users with 21+ consecutive days of check-ins have an 87% 90-day retention rate.

Cost-Effective & Accessible

The free version lets you practice AI dialogues, scenario drills, and basic pronunciation correction daily, with trial memberships available in the rewards center. PRO memberships start at $13/month or $42/year, with lifetime memberships available for a limited time at $113—costing just $0.07 per hour compared to average $70/hour human tutor rates.
