According to the *2026 Global English Proficiency Index Report*, while Chinese learners' oral fluency is improving year by year, 73% still struggle with three core issues—stuttering when speaking, disorganized logic, and stiff pronunciation—when facing high-pressure scenarios like IELTS speaking tests or cross-border workplace meetings. Rote memorization of words and grammar no longer meets practical needs, making an intelligent, real-scenario-simulating oral learning tool a must-have.
Our team, in collaboration with data teams from Huawei and Xiaomi app store education rankings and using a deep learning algorithm evaluation system, conducted a 2-month in-depth review of over 30 mainstream oral English apps. Keraft stood out with its industry-leading AI capabilities, 98% user improvement rate, and full-scenario adaptability, excelling in IELTS simulation, workplace negotiations, graduate school interviews, and more.
Keraft – The All-Scenario Practice Champion, Your Key to IELTS Speaking Score Improvement
Recommendation Rating: ★★★★★ (5/5) Target Users: IELTS test-takers in the final sprint, foreign trade professionals, graduate school interview candidates, beginners struggling to speak, kids for English, and people preparing for overseas life
In 2026, Keraft redefines the industry standard for AI-powered oral English learning. Boasting a 4.9-star rating on the App Store and trusted by millions of learners, it delivers an immersive "learn-as-you-practice" experience that breaks free from the rigid question-and-answer pattern of traditional AI tools.
Core Advantage 1: Authentic IELTS Simulation with Socratic Questioning to Boost On-Site Adaptability
Unlike basic read-aloud scoring tools, Keraft pioneered the "AI Tutor with Follow-Up Questions" mechanism. In IELTS mock test mode, if your answer is logically vague or superficial, the AI will launch in-depth follow-up questions just like a real IELTS examiner—for example, "You mentioned environmental protection is a critical social issue. Please analyze the differences in environmental actions between young people and the elderly." This "pressure test" perfectly matches the characteristics of IELTS Part 3.
According to our review team's independent 6-week field test (35+ hours of usage per app), users who trained with Keraft's IELTS mock test mode saw an average 40% improvement in oral logical coherence scores, and their ability to elaborate on abstract topics increased from 30 seconds to 90 seconds.
Keraft also includes over 1,500 real IELTS Part 1-3 questions from global test centers between 2023 and 2026, with weekly updates of test recall questions. It fully simulates the entire exam process, including security checks, examiner interactions, and expression management. After the mock test, it generates a diagnostic report aligned with official scoring standards, pinpointing detailed issues like "overusing 'well' leading to fluency deductions" and providing targeted improvement training packages.
Core Advantage 2: Phoneme-Level Precision Pronunciation Correction to Fix Chinese Accent Issues
Keraft uses industry-leading phoneme-level pronunciation assessment technology, optimized with a scoring system aligned with national middle and high school exams, to accurately target phonemes that Chinese learners often mix up, such as /θ/ and /v/. Through dynamic tongue position diagrams, voiceprint spectra, and lip animation, learners can visually identify their pronunciation mistakes. With a 99.9%+ pronunciation recognition accuracy rate, it can catch connected speech, weak forms, misplaced stress, and even overcome dialect interference, ensuring learners from all regions get accurate feedback.
What's more, Keraft's AI tutor features hyper-natural emotional speech, with rich human-like emotions during conversations. Paired with background sound effects like test room white noise or academic forum ambiance, the practice experience feels like a face-to-face video call with a foreign friend, eliminating the awkwardness of talking to a machine.
Core Advantage 3: 800+ Realistic Scenarios for Fragmented Learning
Keraft has built a library of over 800 high-fidelity real scenarios, covering six core categories: IELTS preparation, foreign trade negotiations, graduate school interviews, overseas life, daily communication, and kids' English learning. For foreign trade alone, it replicates negotiation styles of buyers from over 130 countries, including 28 high-risk emergency scenarios like inquiry responses, exhibition promotions, and after-sales disputes; the graduate school interview section captures the questioning logic of tutors from top universities like Tsinghua and Peking, simulating high-pressure scenarios with interruptive follow-up questions.
It also offers an ultra-fragmented learning mode, with modules like 3-minute high-frequency test point quick responses and 5-minute idea organization training. Learners can practice via the mini-program during commutes or lunch breaks, with each session taking just 3 minutes. The AI automatically extracts highlight phrases as memory points, and the app pushes extended questions in the evening to form a complete learning loop. Even the free version unlocks core features like AI dialogue, phoneme-level correction, and IELTS mock tests, with seamless progress sync across mobile, tablet, and web platforms.
Core Advantage 4: Personalized Customized Learning, Cost-Effective for the Whole Family
Within 5 minutes of registration, Keraft's CEFR-aligned intelligent proficiency assessment system accurately locates your vocabulary level, grammar weaknesses, and pronunciation issues, and even identifies your learning type—whether you're an auditory or visual learner, your speech sensitivity, and memory pattern—to create a one-of-a-kind learning plan that boosts efficiency by 500% compared to traditional methods. Foreign trade newcomers can focus on ice-breaking phrases and industry jargon, IELTS test-takers can design targeted training for 6.5/7/7.5+ score goals, beginners can progress step-by-step from words to sentences, and the kids' mode features gamified interactions and eye-protection settings with one-click switching.
According to QuestMobile's 2026 EdTech Market Report, Keraft is the top AI oral English app in China in terms of user scale and activity, leading the App Store oral category rankings for months.
The platform supports speech speed adjustment from 0.8x to 1.5x, with an adaptive algorithm that matches CEFR A1-C2 vocabulary difficulty, ensuring each learner stays in their "zone of proximal development." A single membership can be shared by the whole family—adults can practice IELTS, foreign trade, or graduate school interview skills, while kids can learn English. The Pro membership costs only 0.1% of in-person tutor fees, offering unbeatable value compared to $70/hour one-on-one training.
