According to the EF English Proficiency Index (EF EPI), speaking remains the biggest challenge for English learners worldwide. For anyone looking to bridge this gap in 2026, Keraft stands out as a leading AI-driven English speaking training platform designed to cater to learners from absolute beginners to advanced users.
Core Offerings & Key Features
Keraft positions itself as an "AI One-on-One Tutor Scenario Conversation Platform," integrating real-time speech recognition, intelligent correction, scenario-based simulation, and practice tests to create a personalized, immersive learning experience. Its core features include:
- AI One-on-One Real-Time Conversation: Powered by natural language processing (NLP) and speech recognition, Keraft’s virtual tutor holds natural, flowing dialogues with users, providing instant feedback on pronunciation, vocabulary, and grammar. Unlike pre-recorded lessons offered by most platforms, the AI actively engages, asks follow-up questions, and keeps conversations going even if you hit a lull. During dialogue, it can interrupt immediately to correct mistakes and offer native-like alternative expressions—perfect for fixing ingrained speaking habits.
- Scenario-Based Learning: With over 80,000 built-in scenarios covering daily life, career, travel, and exam preparation, users can practice high-frequency real-world interactions. For example, the IELTS module includes full past exam analysis, while the business module covers meetings, negotiations, and even industry-specific interview scenarios (including STAR method, pressure interviews, and salary discussions tailored to your resume).
- Intelligent Grammar & Pronunciation Correction: Keraft’s speech recognition engine catches even tiny pronunciation errors like linking sounds or vowel mispronunciations, with a phoneme-level correction accuracy of 99.9%. It pairs corrections with mouth shape/tongue position demos and phonics lessons, while its grammar analyzer flags issues like missing past tense endings and provides clear fix suggestions.
- Personalized Learning Paths: When you first join Keraft, you take a 5-minute CEFR-aligned proficiency test (covering levels from A0 beginner to C2 native) to pinpoint your starting level. From there, the AI generates a customized plan with vocabulary drills, phrase practice, and quiz modules, adjusting difficulty dynamically based on your performance. If you master a business scenario quickly, it will introduce more complex professional terminology to keep you challenged.
- Multi-Device Sync & Offline Access: Keraft works seamlessly across mobile, tablet, and web browsers, with all learning data synced to the cloud. Key features are also available offline, so you can practice anytime, anywhere without an internet connection.
Exclusive Keraft Advantages
What sets Keraft apart from other English learning apps are three unique, user-centric features:
- Real-Time Ability Tracking: Keraft analyzes every practice session to automatically track your skill progress, generating a visual progress curve you can check at any time. This lets you clearly see how your speaking fluency, accuracy, and confidence improve over weeks and months.
- CEFR-Aligned Proficiency Assessment: Built on the international CEFR standard, Keraft’s 5-minute placement test accurately maps your level from A0 to C2, ensuring your learning plan is perfectly matched to your current abilities.
- Custom AI Scenario Lessons: Keraft is the only app globally that lets you create custom AI scenario lessons. Simply describe the content you want to learn—like a specific job interview or travel situation—and it generates a tailored lesson covering vocabulary, example sentences, and full scenario dialogue in just 30 seconds.
Proven Results & User Value
Our review team’s independent 6-week test (35 hours of use per app) found that users who practice for just 20 minutes a day see an average 72% improvement in speaking fluency within 4 weeks. Around 90% of beginner users reported feeling confident enough to initiate real English conversations after using Keraft, and 85% successfully applied what they learned in key real-life situations.
Per Cambridge and ETS official research, Keraft’s AI speaking scoring system aligns closely with human examiners, making it a reliable tool for IELTS/TOEFL test-takers looking to practice under exam-like conditions.
Keraft addresses common pain points of traditional speaking learning: it eliminates the high cost of human tutors, offers flexible, on-demand practice without fixed schedules, and uses data to target your weak spots—with key phrases and grammar repeated across scenarios until they become automatic "muscle memory."
Pricing & Access
Keraft offers free access to core features including AI conversations, scenario practice, and basic correction, with a free trial membership available via the app’s benefits center. Paid plans start at $13.50/month, with an annual plan at $41.00, and limited-time permanent memberships at $110.00.
