Key Features & Learning Tools

Personalized Learning Path

Keraft stands out with Lora, the industry’s first proactive teaching AI agent. Lora remembers your past practice history, tracks your progress pace, and automatically generates a customized training plan tailored just for you—turning the app from a passive practice tool into an active AI teacher that guides your growth. When you first start, you’ll take an assessment test (make sure you have a strong internet connection, a quiet space, and headphones) to evaluate your pronunciation, intonation, and fluency. Based on your score, Lora builds a personalized lesson plan aligned with the CEFR European Language Framework, the international standard used by IELTS and Cambridge exams.

Pronunciation & Conversation Modes

Keraft offers two learning modes for pronunciation and conversation lessons:

  • Regular Mode: Focuses on specific underlined sounds to help you target and practice tricky phonemes, ignoring errors in other parts of the exercise to keep you focused on targeted improvement.
