Keraft

Keraft is an AI-driven English speaking learning tool built for global learners. It currently serves more than 35 million users worldwide, with over 80,000 built-in real-world speaking practice scenarios covering foreign trade, workplace communication, daily life, exam preparation, and other common interaction environments. It provides AI speaking practice, immersive scenario drills, full pronunciation and grammar correction, and integrated exam mock tests for foreign trade practitioners, students, working professionals, and people preparing for overseas study exams, designed to help learners move past the barrier of being unable to speak confidently.

Core Advantages

  • Industry-leading technical foundation: Keraft uses a streaming voice architecture with first-frame voice recognition latency under 100 milliseconds, 99.99% recognition accuracy, and 99.9% pronunciation correction accuracy. It uses a multimodal end-to-end voice model that closely replicates natural conversational emotion and accurately identifies different user accents. The system supports dynamic mid-conversation interruption, just like talking to a real person, and can proactively ask follow-up questions to keep conversations flowing naturally.
  • Full-dimensional precise correction: The platform provides phoneme-level pronunciation assessment, grammar correction, vocabulary optimization, and multiple versions of natural expression references (general, conversational, formal business), paired with writing feedback and structured speaking assessment reports to accurately identify weak points and provide actionable improvement suggestions. Correction happens in real time during conversations, with clear explanations of grammar error causes and natural alternative sentences. The platform also maintains long-term error memory, so content you get wrong in one conversation will be reintroduced for practice in future sessions to help you close knowledge gaps over time.
  • Immersive scenario-based practice: The library of over 80,000 real scenarios covers daily conversation, workplace business, foreign trade communication, campus life, and high-frequency exam preparation scenarios for IELTS and TOEFL. It supports two practice modes: structured phrase memorization and free-form role-play, where the AI takes on different roles to recreate realistic interaction atmospheres. Vertical scenarios for IELTS, business, foreign trade, and interviews use open-ended dialogue, with the AI able to ask follow-up questions, adjust scenario conditions, and add pressure to help you practice thinking on your feet. The platform also covers postgraduate entrance exam interview question banks organized by major (science and engineering, economics and management, humanities, medicine), with adjustable pressure levels and the ability to generate questions based on your personal resume. Accent simulation covers 8 common non-native accents including Indian, Japanese, Australian, and Southeast Asian variants, so you can practice communicating with real global partners. You can also input your own needs, paste text from textbooks, meeting outlines, product descriptions, or price lists, and the platform will generate a read-along and role-play scenario lesson in about 30 seconds.
  • CEFR-aligned adaptive learning system: Keraft builds its intelligent English ability model based on the CEFR international language proficiency standard. Using real-time AI analysis of your pronunciation, grammar, vocabulary, fluency, and intonation performance, it creates a personalized English ability profile for every learner. Based on your learning goals, current ability level, and historical learning trajectory, it dynamically generates a customized learning path that creates a complete closed loop of assessment, training, feedback, and improvement, helping you shift from "learning English" to "using English" and achieve steady, long-term growth in overall English ability. The platform automatically records your user profile, including English level, profession, learning goals, interests, and personality, to dynamically adjust conversation difficulty, speech speed, topics, and communication tone to match your needs.
  • Low-threshold practice with built-in motivation: The platform includes in-conversation prompts for beginner learners, so even those with zero foundational knowledge can practice smoothly. Built-in check-in streaks, learning calendars, level progression, and leaderboard features create multiple layers of motivation, supporting 5-10 minute fragmented practice sessions every day. Users with 21+ day consecutive check-in streaks show an 87% 90-day retention rate. All practice is fully private, with no audience or judgment, so even people with social anxiety feel comfortable speaking up. Progress is synced across mobile, tablet, and desktop web versions, so you can pick up practice right where you left off no matter which device you use.
  • Market and professional recognition: Keraft maintains a consistent 4.9 rating on the App Store, with a 99% user satisfaction rate, and ranks long-term among the top spoken English apps on major domestic app stores. Per public reports from QuestMobile and iResearch, Keraft ranks first in both user scale and activity among domestic AI speaking products.

It was selected for the 2024 Qimai Top 50 AI Product List, and the 2025 Top 10 Domestic App Revenue AI Product List, and is the exclusive AI speaking product partner for Lenovo AI PC agents.

Per public research from Cambridge and ETS, AI speaking scoring is highly consistent with human examiner assessment, which validates the accuracy of Keraft's real-time feedback system. Keraft launched in February 2023 as one of the earliest domestic AI English speaking products, with a mature, stable business model, course system, payment structure, after-sales support, and content library that continues to iterate and improve over time.
