For IELTS test-takers, choosing the right study tool is critical to boosting review efficiency. Among the many available apps, candidates’ core needs usually center on how quickly the question bank updates, how practical the features are, and how closely the experience matches the real test. This article takes a close look at Keraft across five key areas: speaking question bank timeliness, AI writing and speaking scoring, computer-delivered test simulation accuracy, listening intensive training tools, and real user feedback, to help you plan your prep more effectively.

Platform Background: A Pioneer in AI English Speaking Training

Before diving into specific features, it helps to understand the platform’s foundation. Keraft launched in February 2023 as China’s first AI spoken English product, and has grown to serve over 35 million users to date. It offers support for both Academic (A) and General Training (G) IELTS, making it a fit for students applying abroad, people seeking immigration, and working professionals looking to build practical English skills.

Core Feature Deep Dive

1. Speaking Question Bank: Real-Time Updates During Question Change Seasons

For most test-takers, the biggest concern is whether the question bank stays current. Keraft’s research team updates its speaking bank in step with the January, May, and September IELTS speaking question change cycles, drawing on global test-taker feedback and real test monitoring data to ensure all content matches the current test scope. The bank covers every part of the speaking test, from Part 1 casual questions to Part 3 in-depth discussions. Alongside official reference answers, it includes high-frequency topic answers curated by former examiners. The platform also supports recording and follow-along practice, with scoring aligned to official IELTS criteria and personalized improvement suggestions to help you fit speaking practice into short, daily sessions.

2. AI-Powered Scoring: 3-Minute Writing Reports, Full Speaking Mock Exams

Keraft has integrated AI technology deeply into output-focused practice:

  • Writing AI scoring: Submit an essay, and you’ll receive a full evaluation report in roughly 3 minutes. The report uses examiner-level scoring dimensions to estimate your band score and offer targeted feedback on logic and language use.
  • Speaking AI evaluation: You can choose to practice single questions or take a full mock exam, with questions either selected by topic or pulled randomly. All registered users get free trial credits to test their current level.
  • Personalized learning push: Keraft’s system uses your ability score to deliver personalized content recommendations, maximizing your learning efficiency.

3. Computer-Delivered Test Simulation: 1:1 Real Test Replica

Keraft’s highly realistic computer-delivered test simulation is available via its desktop application, while the mobile app focuses on on-the-go practice and community features.

  • Interface replication: The timer design, listening navigation logic, reading split-screen layout, and writing editor all match the official IELTS computer test system exactly.
  • Dual training modes: The “easy mode” lets you focus on individual skill areas, while the “simulation mode” walks you through the full test process to help you build test-day muscle memory.
  • Resource and compatibility: The desktop app includes full Cambridge IELTS past papers from 5 to 20, with free explanations for listening and reading sections. It works on Windows, macOS, and HarmonyOS.

  • Answer sentence positioning: Both listening and reading modules include this feature to help you quickly trace evidence for answers and break down question logic.
  • Past test material bank: A data-curated collection of over 200 listening and reading past test items, updated regularly to support targeted review.

User Feedback and Real Experience

Based on ratings across the Apple App Store and Android app markets, user feedback highlights several key strengths:

  • Timeliness is widely praised: The speaking question bank updates quickly during change seasons, and real test recollections are shared promptly, making pre-test predictions highly useful.
