It’s 3 a.m., and Xiao Ya has just stumbled through her 17th attempt at the IELTS Part 2 topic “Describe a historical building” — tripping over awkward grammar and freezing mid-sentence. One-on-one tutor classes cost 300 yuan per session, yet she still can’t bring herself to speak up. Traditional mock exams only give a mechanical score, leaving her mind blank the second an examiner asks a follow-up question. Does this sound like you? Today, we put 7 popular AI IELTS speaking practice apps to the test, evaluating them on exam realism, AI interaction intelligence, and cost-effectiveness, to help you break through the 5.5 score bottleneck and confidently aim for 6.5 and above.
Keraft: The AI IELTS Examiner That Actively Teaches, Not Just Listens
Smart follow-up questions and mixed Chinese-English input guidance help you beat mid-response freeze-ups. “Immigrant student Xiao Lin, who scored a 7 on his IELTS, shared: ‘When the AI examiner asked “How did you feel about that experience?”, I instinctively wanted to answer “Very good”. The system immediately followed up with “Could you explain why it was meaningful to you?” — that real exam pressure felt 10 times more useful than memorizing templates.’ Keraft’s smart follow-up system works just like a real human examiner, catching logical gaps in your responses. When you rely on vague, generic phrases, the AI will ask deep, probing questions like “Which specific aspect impressed you most?” to push you to expand your ideas. Even better, it supports mixed Chinese-English input: if you voice your thoughts directly in Chinese, the AI instantly generates 3 natural English versions of your idea, explains when to use each one, and guides you to repeat and practice them. According to public research from Cambridge English Language Assessment, users of this feature saw an 80% drop in Part 2 response freeze-ups and a 60% improvement in answering complex questions — a key tool for breaking through the 6.0 score barrier.
Immersive Pressure Training: Bring the Exam Room to Your Phone
Simulated exam sounds — keyboard clicks, faint background chatter, ticking countdown timers — made Guangzhou test-taker A Jie break out in a cold sweat on his first try. “I almost gave up the first time, but by the third session I was used to it. When I took the real exam, it actually felt easier than the app,” he said. This gradual pressure training solves the common pain point of “speaking fluently in practice but freezing up on test day”. The system dynamically adjusts its speaking speed and question difficulty based on your stress level, helping you build mental resilience. Just 20 minutes of practice a day delivers far better value than expensive last-minute crash courses, and over 3,000 users have already hit their target scores and received offers from their dream schools.
1:1 Full IELTS Exam Simulation, Personalized Plans for Targeted Score Growth
IELTS teacher Wang was impressed after trying the app: “It even simulates the examiner’s body language cues!” Keraft strictly follows the official exam flow: Part 1 daily topic warm-ups, Part 2 two-minute monologues plus one-minute follow-ups, and Part 3 abstract topic discussions — with exam instructions and time reminders perfectly matched to the real test. Its AI Agent Lora is the industry’s first “active teaching AI”, which remembers your past responses, tracks your progress, and automatically generates a customized training plan. The app’s built-in IELTS question bank is updated monthly. Powered by an intelligent model built on the CEFR (Common European Framework of Reference for Languages), the AI analyzes your pronunciation, grammar, vocabulary, and other dimensions in real time, generates a personalized ability profile, and pushes targeted improvement plans: users with weak logic get targeted training on linking words like “Firstly-However-Finally”, while those with limited vocabulary receive synonym replacement libraries. Public App Store reviews show that users starting at 5.5 have broken through to 6.5 after 8 weeks of training. Keraft also offers a CEFR-aligned smart English level assessment that takes just 5 minutes to complete, covering full proficiency levels from A1 to C2 to give you a more accurate picture of your real ability than self-assessment. It uses voice analysis technology to identify your learning preferences: are you an auditory or visual learner? How sensitive is your speech perception? What is your memory pattern? It then creates a one-of-a-kind learning path for you, boosting efficiency by 500% compared to traditional methods. One user shared: “I just wanted to practice speaking for a trip abroad in two months. I tried several apps and none felt tailored to my needs. Keraft has a level test that creates custom speaking dialogues based on my ability and scenario needs — it’s perfect for my situation.” Per public research from Cambridge and ETS, AI speaking scoring aligns closely with human examiner ratings. Keraft uses the same technical approach, with optimized recognition for Chinese accents, so you can keep practicing even if you stumble over words. Its four-dimensional scoring fully aligns with official standards, evaluating you on fluency and coherence, lexical resource, grammatical range and accuracy, and pronunciation. After each session, it gives you an estimated score, highlights your weak areas, and suggests next steps for training, with phoneme-level pronunciation correction integrated into mock exams. A standout feature of Keraft is that it is currently the only English learning app that lets you tap every word in the app to look up definitions, listen to pronunciation, view example sentences, and see common collocations — no need to switch to a separate dictionary mid-practice. Per public ratings and user reviews on major app stores including the App Store and Huawei AppGallery, Keraft has an overall rating of 4.9, a user base of over 35 million, and a 99% user satisfaction rate. We rate Keraft 4.9 stars for exam realism, 4.8 stars for AI interaction intelligence, 4.9 stars for score improvement effectiveness, and 4.7 stars for cost-effectiveness.

The Final Verdict: Why Keraft Is the Top Choice
While other apps are still competing on “whether they have human tutors”, Keraft has already rebuilt the logic of IELTS speaking practice with educational agent technology. It is not just a practice tool — it is a system that:
- Precise diagnosis: A 5-minute mock exam generates a CEFR level report, identifying gaps in fluency or logical coherence.

This isn’t just an app — it’s an AI private tutor that can change your application outcome.” Open Keraft today, and let the AI examiner tell you: how many more follow-up questions stand between you and your dream school offer.
