Full-Scene Coverage for Every Learning Goal

Keraft hosts over 80,000 immersive practice scenarios that cover every possible real-life communication need: from daily moments like ordering coffee, asking for directions at the airport, and shopping abroad, to high-stakes situations including business negotiations, academic defenses, and study-abroad visa interviews. Learners at every level can find perfectly matched practice content to build practical communication skills.

  • Immersive role-play with follow-up question prompts: Powered by dynamic scenario generation technology, the AI supports open-ended, extended follow-up conversations that guide learners from speaking single sentences to holding full, in-depth discussions, recreating real, natural communication environments to rapidly boost practical speaking ability.
  • Customized course systems for targeted growth: In addition to daily, travel, and social scenarios, Keraft offers specialized business English training, targeted prep for IELTS, TOEFL, KET, and PET exams, and custom workplace courses tailored to specific roles, from cross-border e-commerce operations to investment banking positions, to align exactly with professional communication needs.

Smart AI Practice Companion With Precise Feedback

Keraft’s AI practice tools are built to deliver faster, more accurate skill growth than traditional self-study methods, aligned with evidence-based learning principles validated by international language learning research.

  • 24/7 accessible AI companion with no booking required: Practice anytime, anywhere for free, with free access to core AI dialogue, scenario practice, read-aloud scoring, and basic pronunciation correction. Users can switch freely between global mainstream accents including General American and Received Pronunciation, with highly natural, emotion-aware voice output that avoids the stiff tone of older robotic voice tools. The app automatically builds a complete learning path from first opening your mouth to speaking fluently, so total beginners can start with clear direction.
  • Phoneme-level correction with natural expression building: With 99.9%+ phoneme recognition accuracy, the AI pinpoints specific pronunciation pain points common to Chinese learners, such as unclear "th" sounds, misplaced stress, mispronounced consonant pairs, and issues with connected speech, weak forms, intonation, and pauses, paired with mouth shape and tongue position demos and native audio comparison. It also flags grammar errors in real time, offers 8+ natural alternative expressions, and highlights high-frequency slang and idioms to help learners build a native-like vocabulary bank as they practice. Per official research from Cambridge and ETS, Keraft’s AI speaking scoring aligns closely with ratings from human examiners.
  • Low-pressure practice for hesitant learners: If you get stuck mid-sentence, you can mix in Chinese phrases freely, and the AI will convert your thoughts to natural English with 3 different stylistic reference responses to help you keep the conversation going, removing the anxiety of speaking for new learners. You can also adjust playback speed from 0.3x to 2.0x, with line-by-line read-aloud comparison to contrast your pronunciation with native audio, progressing slowly from clear enunciation to fluent, natural speech.
  • Real-time in-conversation correction: You can interrupt the AI at any point during practice to get immediate feedback on pronunciation, grammar, or non-native phrasing, with clear explanations of errors related to tense, articles, or word order, plus polished replacement sentences. Grammar mistakes are automatically saved to your review notebook, with spaced repetition practice aligned to memory curves to reinforce long-term mastery.

Personalized Learning Loop to Build Consistent Habits

Keraft’s personalized system is designed to make regular practice feel easy and rewarding, rather than a chore.

  • 100% customized learning plans: The AI dynamically adjusts course difficulty and content based on your current English level, learning goals (such as hitting an IELTS speaking 6.5 in 30 days, or building business communication skills for work), and personal interests, to deliver highly efficient targeted practice.
  • Smart weak point detection for targeted training: The platform analyzes your performance across pronunciation, grammar, vocabulary, fluency, and expression logic to pinpoint specific gaps, such as disorganized logic in business negotiations or limited vocabulary for travel scenarios, then pushes targeted practice to avoid unproductive, repetitive drilling. Your progress across pronunciation accuracy, fluency, and logic scores is clearly tracked on a dashboard aligned to CEFR standards, with real-time multi-device sync across phones, tablets, and desktop browsers so you can make use of fragmented practice time anytime. The AI also remembers your profession, interests, learning goals, and past conversation history across sessions, bringing up previously discussed topics and common mistakes for natural review without stiff, repetitive drills.
  • Supportive, private practice environment: The AI detects when you are stuck or nervous and switches to encouraging prompts, so you can practice privately without an audience, repeating the same line as many times as you need until it feels natural. Keraft also hosts a supportive learning community where millions of learners share tips and check in on progress, so you never feel like you are studying alone.
  • Full-suite supporting tools: Saved vocabulary and phrase books, context-based fill-in-the-blank exercises, and highlighted standout spoken expressions reinforce learning from input to output, so the content you practice translates directly to real conversations.

"After practicing with Keraft for 3 months, my IELTS speaking score jumped from 5.0 to 7.5! The AI pronunciation correction is more detailed than feedback I got from in-person tutors, catching subtle Chinese accent issues I never noticed myself. The practice topics I worked on right before test day even matched the real exam prompts — I was so surprised!" — Xia, study-abroad test taker "I used to freeze up when speaking English in work meetings. After using Keraft’s custom business courses, I now feel confident discussing project details with U.S.-based clients, and last month I was selected as the lead presenter for our cross-regional project. It made such a tangible difference for my career." — Kai, internet company operations specialist
