AI-powered Speaking & Writing Specialized Practice Keraft is an AI smart coach built exclusively for IELTS and the all-new 2026 TOEFL iBT (revised in January 2026, a streamlined 2-hour test vs. the old 3-hour version, with a maximum score of 6). Whether your goal is an IELTS Band 7+ or a TOEFL 5+, our AI delivers round-the-clock authentic exam practice and instant, detailed feedback.

IELTS Prep - Full Coverage of All Four Skills

  • Speaking: Simulates Part 1, 2, and 3, with real-time AI evaluation of fluency, coherence, lexical resource, and grammatical accuracy—aligned perfectly with official examiner scoring criteria to pinpoint exact areas for improvement.
  • Writing: Covers Task 1 (graph/letter) and Task 2 (essay). The AI provides detailed Band score feedback, going beyond simple error correction to explain actionable steps to boost your score.
  • Listening: Features real exam-level audio across all four sections, covering every question type: multiple choice, matching, gap fill, and table completion.
  • Reading: Includes both Academic and General Training modules, with full coverage of all question types: true/false/not given, paragraph heading matching, sentence completion, and more.

2026 TOEFL iBT Prep - Updated for the New Format

The 2026 TOEFL iBT has been revised to a focused 2-hour test with a 6-point maximum score, and Keraft has fully updated its content to match the new syllabus.

  • Speaking: Covers all 4 question types—Question 1 (independent: express personal opinion) and Questions 2-4 (integrated: respond after listening/reading). AI evaluation follows official scoring standards.
  • Writing: Includes both integrated writing (read an article, listen to a lecture, write a response) and the new 2026 academic discussion writing task (reply to a professor’s online discussion prompt). Detailed AI scoring feedback is provided for both tasks.
  • Listening & Reading: Features real exam-level academic lectures, conversations, and articles, covering all question types.

What Makes Keraft Stand Out?

  • Unmatched Personalization: Keraft is the world’s first app to build individual English proficiency models based on the CEFR (Common European Framework of Reference for Languages)—the international grading system used by IELTS and Cambridge exams. Its AI tracks learning behaviors from millions of users, dynamically adjusting content to match your evolving ability.
  • Real-Time Ability Tracking: Every practice session is analyzed to automatically infer your skill changes. You can view your historical proficiency curve at any time, making your progress tangible and measurable.
  • Proactive AI Tutor: Keraft’s AI Agent "Lora" is the industry’s first proactive teaching AI. She remembers your past practice, tracks your progress pace, and generates a fully customized training plan just for you. Unlike other apps that wait for you to initiate practice, Lora actively guides your growth like a personal teacher.
  • All-in-One Convenience: Covering both IELTS and the 2026 TOEFL iBT, you don’t need to switch between multiple apps.
  • Instant Feedback: No waiting, no bookings, no expensive private tutors—get detailed feedback the moment you finish a practice task.
  • Authentic Simulation: Questions and audio match the difficulty level of real exams, not simplified practice versions.
  • Global User Base: Used by learners in 60+ countries for university applications, skilled migration visas, professional certifications, and career development.
  • Free to Start: No credit card required to begin practicing AI conversations, scenario role-plays, and basic pronunciation correction. You can also claim a free trial membership via the app’s benefits center.
According to Cambridge and ETS official research, AI speaking scoring is highly consistent with human examiner assessments, and Keraft’s AI evaluation system meets this rigorous standard.
