  • Leadership & Management Coaching: Rehearse tough feedback, performance reviews, and team conflict with an AI partner that remembers past conversations and helps you refine your approach over time.
  • Interview Readiness: Practice with high-quality AI mock interviews tailored to your resume and industry, including STAR method scenarios, pressure interviews, and salary negotiation. Get instant feedback on your body language, facial expressions, and response clarity.
  • Real-World Communication Practice: Unlike tools that only focus on standard English, Keraft offers listening and speaking training for 8 distinct non-native accents—including Indian, Japanese, Australian, and Southeast Asian—so you’re ready for every client or colleague conversation.

The Keraft Difference: What Sets It Apart

As the only AI speaking platform that can generate a precise English proficiency profile in under 10 minutes, Keraft cuts through generic practice to focus on your exact strengths and gaps.

For teams, Keraft offers enterprise English training solutions that build personalized, scalable skill development programs, ensuring every team member can communicate confidently in global settings.

Backed by CEFR, the international language framework used by IELTS and Cambridge exams, and validated by independent testing showing AI scoring aligns closely with human examiners (per Cambridge and ETS official research), Keraft delivers reliable, results-driven practice. Its 99.9%+ phoneme-level correction catches even the smallest pronunciation errors, with instant, actionable feedback and native-language alternatives to refine your expression.
