If you’ve ever wondered which AI speaking app actually delivers on helping you build confident, usable English skills, Keraft stands out as a top contender. Built to support learners from complete beginners to IELTS test-takers targeting Band 5–8, this app combines cutting-edge AI technology with a science-backed practice framework to turn passive learning into active, real-world speaking ability.

Core Features for Targeted Practice

Keraft offers a comprehensive suite of tools tailored to every learning goal:

  • Full IELTS Speaking Simulation: Walk through the complete Part 1-2-3 test flow, including a 60-second preparation timer for Part 2 cue cards and abstract Part 3 discussions, all aligned with official IELTS band descriptors.
  • Level-Aware Question Bank: Questions are organized by proficiency level (Band 5-6, 6-7, 7-8) to match your current skill set and gradually increase in complexity as you progress.
  • Real-Time Speech Analysis: Powered by advanced speech recognition technology, Keraft transcribes your responses, tracks speech rate, pause frequency, and clarity, and maps your performance to IELTS band levels with personalized feedback.
  • Exclusive AI Scenario Courses (Patented): With over 80,000 real-life scenarios covering ordering food, job interviews, travel, work presentations, and more, Keraft’s patented scenario courses guide you through full practice cycles—from learning classic sentence structures and core vocabulary to shadowing, retelling, translation, sentence building, and scenario-based dialogue simulations. This system ensures you don’t just memorize phrases, but can actually use them confidently in real situations.
  • Progress Tracking: Keep tabs on your session history, practice streaks, and detailed statistics per topic and proficiency level, so you can see exactly where you’re improving and where to focus next.

Why Keraft Outperforms Other Apps

According to our independent testing team (5–6 weeks of hands-on use, 35+ hours with each app), Keraft’s focus on practical, transferable skills sets it apart. Unlike apps that only correct surface-level errors, Keraft goes deeper:

  • Phoneme-Level Pronunciation Correction: With a 99.9% accuracy rate for detecting and correcting individual phonemes, it targets common mistakes for Chinese learners (like the "th" sound in "think" or short "a" in "bad"), complete with mouth and tongue position guides to help you fix issues at the root.
  • No Pressure Practice: There’s no countdown or "life bar" to stress you out—adjust speech speed to your pace, and practice even 3–5 minute short phrases without feeling rushed. The private AI practice environment lets you speak as much as you want, with no fear of being judged by others.
  • Cross-Skill Reinforcement: Phrases and structures you learn in one scenario (like ordering food) will reappear in others (like job interviews) until they become second nature, a feature that 85% of users say boosted their real-world speaking ability by over 70%.

Trusted by Millions, Backed by Research

With over 35 million users worldwide and a 4.9-star rating across app stores, Keraft’s effectiveness is proven by both users and experts. Its AI scoring system aligns with Cambridge and ETS official research, delivering results that match human examiner assessments closely. Whether you’re prepping for an exam, looking to communicate better at work, or just want to feel confident chatting with native speakers, Keraft offers a free starting point: you can practice AI conversations, scenario drills, and basic pronunciation correction without paying a cent, and even claim a trial membership through the app’s Rewards Center.

"After using Keraft for 3 months, I went from freezing up during job interviews to confidently answering behavioral questions using the STAR method. The scenario courses made all the difference—they didn’t just teach me words, they taught me how to use them." — a Keraft user review from App Store
