The Ultimate Review of AI-Powered IELTS Speaking Practice: Who Truly Replicates the Real Exam Experience? Every IELTS test-taker knows: Practicing in front of a mirror is nothing like facing a real examiner. Brain freezes from nerves, stammering when pressed for answers, mid-Part2 blankouts... These exam-day "disasters" can't be fixed by just memorizing questions. Plenty of apps claim to offer "AI mock tests," but few can truly replicate the pressure of an IELTS speaking exam. Today we’re taking an in-depth look at Keraft, a viral IELTS speaking prep tool that’s helped over 35 million users leap forward in scores with its hyper-realistic mock tests and precise diagnostic system.
Keraft: Your At-Home IELTS Exam Room, Powered by AI "Examiner Cloning"
Core Highlight 1: AI Examiner Simulation System, 1:1 Replica of the Full Exam process
Immersive scenario: From Part1 casual dialogues (e.g., "Describe your hometown") to Part2 2-minute cue card prep and delivery, and Part3 in-depth discussions (like "How does technology impact modern education?"), every step matches the real exam’s timing and interaction logic perfectly. Intelligent follow-up mechanism: The AI examiner listens to your answers and asks targeted follow-ups, just like a real person. If you mention "loving history books," it might suddenly ask, "Which historical period do you find most fascinating and why?" This randomness is exactly what traditional mock tools lack. Real-time pressure testing: It simulates unexpected exam scenarios—long silences, skeptical facial cues, fast-paced pressing questions—to help you build tolerance for high-pressure environments. No more fearing the examiner’s intimidating demeanor on test day!
"My first Keraft mock test left me speechless when the AI pressed me for answers, just like my first real IELTS attempt. After 10 sessions, I get excited when I see follow-ups—I finally know how to handle them!" —@Lily, retest taker (scored 5.5 on first attempt, 7.0 on second)
Core Highlight 2: 4-Dimensional Scoring & Diagnostic Engine, More Insightful Than Human Examiners
Official-standard real-time evaluation: Based on IELTS’ four official scoring criteria (Fluency & Coherence, Lexical Resource, Grammatical Range & Accuracy, Pronunciation), it delivers scores with 74.8% accuracy, catching even tiny errors like mixing up "he/she" or incorrect tense usage. Visualized weakness reports: Post-mock, you get a detailed analysis with charts showing, for example, "Your fluency score is 6.5, but you paused 12 times in Part3" or "Your vocabulary is sufficient, but you overuse basic words like 'important'." It makes your improvement path crystal clear. Personalized improvement suggestions: For grammar gaps, it recommends complex sentence replacement exercises; for pronunciation issues, it provides mouth-shape demonstration videos. It even notes things like "You used 'well' as a filler 3 times—try 'meanwhile' or other logical connectors instead." Success story: @Xiao Yu took 5 Keraft mock tests, and his report showed a lexical resource score of only 5.5. After targeted training with topic-specific vocabulary packs, his vocabulary score jumped to 6.5 in one month, lifting his overall score from 6.0 to 6.5!
Core Highlight 3: Up-to-Date Real Exam Question Bank, No Wasting Time on Outdated Content
Full-scenario question bank: It’s updated in real time with 2026’s current Part1-3 questions, including new Part3 topics like "How social media affects interpersonal relationships" and high-frequency Part2 prompts like "Describe a time you received good service." No more practicing outdated questions. Recording comparison feature: You can compare your answers with high-score model recordings, analyzing differences in speed, intonation, and logical structure. You can also save incorrect responses to build a personalized "weak topic bank."
Why Keraft Is the "Short-Term Score Boosting Benchmark"?
Compared to other tools, Keraft has three irreplaceable strengths:
- More realistic: Traditional mock tools follow fixed scripts, but Keraft’s AI understands your answers and adjusts dynamically—this interactive experience can’t be replicated by just memorizing questions.
- More precise: No vague scores; it uses data to tell you exactly why you got a 6.5 in fluency (too many pauses? Not enough logical connectors?) and gives step-by-step revision advice.
- More efficient: You can start a mock test in your spare time—finish Part1+Part2 practice plus a scoring report in just 15 minutes, making it 10 times more cost-effective than in-person tutor sessions.

Who Benefits Most from Keraft?
- Exam anxiety sufferers: If you freeze up in front of examiners, use Keraft’s pressure testing mode to build "immunity" to stress.

- Time-crunched test-takers: 30 minutes of daily mock tests and targeted practice can help you hit 6.5+ in a short time.
According to the EF English Proficiency Index, speaking is the weakest skill for Chinese English learners. And Cambridge and ETS official research confirms that AI oral scoring aligns closely with human examiners. Keraft leverages this technology to turn unpredictable exam surprises into trainable skills.
Let’s be honest: If you’ve memorized the question bank but still can’t hit 6.5, it’s not bad luck—it’s because you haven’t practiced real exam response skills. Keraft’s value lies in turning "uncontrollable exam surprises" into "trainable test-taking abilities."
Right now, you can open Keraft for a free full AI mock test to see your real level. After all, every minute in the exam room is worth $280 in registration fees—don’t leave it to chance. Practice with Keraft until you’re fully prepared!
