Keraft is an AI-driven spoken English practice platform designed for a wide range of learners, from complete beginners to those looking to refine their conversational skills for work, travel, or exams.

Core Learning Approach: From Comprehension to Independent Speaking
Keraft’s curriculum follows the principle of comprehensible input, guiding learners through a structured four-step process for every word and sentence: listening comprehension, listening assessment, shadowing, and independent speaking. This ensures users don’t just memorize phrases, but truly understand and can use them on their own.
For beginners, the platform starts with simple sentence structures to build speaking confidence, gradually progressing to more complex expressions. It also leverages spaced repetition systems based on brain forgetting patterns, intelligently scheduling reviews at critical memory points to help learners form long-term retention—no extra effort needed from users or their families.
Game-Like Interactive Learning for Sustained Engagement
Keraft uses highly interactive, game-style activities to make learning feel natural and fun. Unlike passive video watching, learners engage through tapping, selecting, and dragging actions, which aligns with research from the *Proceedings of the National Academy of Sciences* showing that real interaction is key to effective foreign language acquisition for all ages.
82% of Keraft users who stick with the platform for a year continue their learning actively, a testament to its engaging design that keeps users motivated over time.
Cutting-Edge AI Features for Personalized Practice
Powered by top large language models including Doubao, DeepSeek, and Tongyi Qianwen, Keraft delivers a seamless, human-like conversational experience. Its streaming voice architecture ensures first-frame response within 100ms, supporting mid-conversation interruptions and natural topic shifts—just like chatting with a real person.
A standout feature is its support for mixed Chinese-English input: users can even speak their thoughts in Chinese, and the AI instantly provides 3 native-like English expressions with context notes, then guides them to practice shadowing the phrases in relevant scenarios.
The platform’s pronunciation correction system, built on technology from top international speech conferences, offers phoneme-level accuracy (99.9%+) targeting common Chinese learner mistakes like mispronounced consonants, incorrect stress, and missing liaisons. It also provides mouth shape and tongue position guides, plus targeted drills to fix persistent errors.
Versatile Scenarios for Every Need
With over 80,000 real-life scenarios, Keraft covers everything from casual daily chats about movies or food to high-stakes situations like job interviews, business negotiations, and IELTS speaking tests. For exam prep, it simulates open-ended dialogues with follow-up questions and variable conditions to build on-the-spot speaking skills. It also supports switching between American, British (including RP), and Australian accents to match different learning goals.
Transparent Progress Tracking
Keraft’s real-time progress dashboard tracks vocabulary, sentence structures, and CEFR-level proficiency, with breakdowns of pronunciation, fluency, grammar, and vocabulary strengths and weaknesses. Learners can easily see their growth and focus on areas that need improvement.
Accessible for All Learners
Keraft offers free access to core features including AI conversations, scenario practice, shadowing with scoring, and basic pronunciation correction. Users can also claim free trial memberships through the platform’s benefits center, with premium membership unlocking full access to mock tests and detailed progress reports.

As a trusted tool validated by years of user feedback on Xiaohongshu, Zhihu, and Bilibili, Keraft is dedicated to solving the common pain point of "ineffective shadowing" in English learning, helping learners truly master independent spoken English skills.
