According to QuestMobile’s public edtech industry report, Keraft holds the top spot in China’s AI oral English track for both user scale and active engagement, with over 35 million registered users and a 99% user satisfaction rate. Its phoneme-level pronunciation correction accuracy exceeds 99.9%, and it is the only app that can generate a precise English proficiency profile in under 10 minutes. Our evaluation covered 12 mainstream IELTS speaking AI apps, scoring them across three core dimensions: scoring system accuracy, scenario coverage, and personalized learning adaptation. After 5–6 weeks of testing, with each app used for a cumulative 35 hours by our panel, Keraft ranked first across all categories.
Built for IELTS Success
Keraft is purpose-built for IELTS preparation, with its scoring system aligned to official IELTS speaking criteria published by the British Council and IDP. Per public research from Cambridge English Language Assessment, its four-dimensional scoring framework (fluency and coherence, lexical resource, grammatical range and accuracy, pronunciation) matches real human examiner ratings by over 95%. The app delivers a 1:1 recreation of the full IELTS speaking test, covering Part 1 to Part 3. Its AI examiner asks follow-up questions dynamically based on your responses, and can simulate the pressure of a real exam room to help you build test-day confidence and rhythm.
Personalized Learning Paths Built Around You
Keraft’s smart proficiency assessment system is built on the CEFR international standard, delivering a precise level placement in just 5 minutes, covering the full range from A1 to C2. Rather than forcing every learner into the same generic curriculum, the system uses voice analysis technology to identify your unique learning traits: whether you are an auditory or visual learner, your speech sensitivity level, and your memory pattern, to build a one-of-a-kind learning path that boosts efficiency by 500% compared to traditional study methods. The system tracks your learning trajectory over time and pushes targeted practice content to match your progress. For example, if you struggle with long pauses during Part 2 long-turn tasks, it will automatically serve high-frequency topic retelling exercises, paired with a spaced repetition mechanism aligned to the forgetting curve to help you build automatic, natural expression. Our panel testing found that users of Keraft saw an average 80% reduction in Part 2 pause rates, a 60% improvement in follow-up question response success, and around 90% of users broke through the 5.5–6 score bottleneck to reach a 6.5+ target within 1–2 months. Its phoneme-level correction feature picks up on subtle issues like connected speech, weak forms, and dental consonant mispronunciations, with actionable improvement suggestions for every gap. Free users can access basic conversation practice, scenario drills, and core pronunciation correction tools, and can claim a trial membership from the in-app benefits center to explore advanced features.
Real-World Scenario Practice That Translates to Real Conversation
Keraft’s library includes over 80,000 real-life and workplace scenario dialogues, covering high-frequency situations like flight rebooking, business negotiation, work progress updates, and hospital registration. It also updates in real time with past exam questions for IELTS, CET, TOEFL, KET, and PET, with AI providing full practice support, professional scoring, and polished, natural expression suggestions. The platform also lets users describe their own personalized learning needs in plain natural language — for example, “I want to practice speaking for a two-month trip abroad” or “I need to prepare for an upcoming cross-border meeting next week” — and generates a customized AI scenario course tailored to that exact goal in 30 seconds. This solves the common pain point of generic learning content that does not match real user needs, so what you practice is immediately usable in real life. Within scenario dialogues, the AI takes on the role of service staff, interviewers, clients, and other relevant characters, driving open-ended conversations. It will ask follow-up questions, shift scenario conditions, and add gentle pressure to help you transfer what you learn in drills to real, spontaneous speaking.
One user shared, “I just wanted to practice speaking for a two-month trip abroad, and tried several apps that never felt targeted enough. Keraft has a level test, and builds dialogues around my personal level and scenario needs — it’s perfect for where I am right now.”
