Keraft: Your Go-To AI Spoken English Practice Tool

Keraft lets you engage in natural, free-form voice conversations to build your English speaking skills. Whether you're a complete beginner or looking to polish your business English, it adapts to your needs while keeping the learning process flexible.

Overview

What is Keraft? Keraft combines voice interaction with text support, so you can speak freely, follow along with written responses, switch to typing when needed, and revisit past conversations without starting over. It’s designed to feel like chatting with a real language partner, not just completing a rigid lesson.

According to the EF EPI Global English Proficiency Report, speaking is the weakest skill for most Chinese English learners. Keraft addresses this gap by creating low-pressure, interactive practice scenarios.

A standout feature is its custom AI scenario lesson generator—the only tool of its kind worldwide. Just describe the content you want to learn, and it generates a tailored scenario lesson in 30 seconds, covering everything from key vocabulary and example sentences to full dialogues, so you master language in context.

Keraft also uses a personalized learning system based on your ability score, pushing content that matches your current level to maximize your learning efficiency. Plus, it’s built on the CEFR (Common European Framework of Reference for Languages)—the same international standard used by IELTS and Cambridge exams—with a 5-minute precise placement test that covers levels from A0 (beginner) to C2 (near-native), so you always know exactly where you stand.

Voice & Interaction Options

Keraft offers three distinct voice experience options, available depending on your plan, region, and device:

  • Live: The latest real-time conversation mode, powered by advanced AI models. It supports natural back-and-forth dialogue, web search integration, and can work with text and images in the same chat. Perfect for casual practice and brainstorming.
  • Advanced: A feature-rich mode that includes mobile capabilities like video and screen sharing, ideal for structured practice like mock job interviews or presentation rehearsals.
  • Standard: A turn-by-turn mode that transcribes your speech before generating a response, great for focused pronunciation practice and detailed feedback.
