Real Experiences from Actual Users
"I finished my center classes and now study independently with Keraft, so I can compare pretty clearly. Task 1 feels a bit stricter here, while Task 2 is around +/- 0.5 compared with the center, so it seems quite reliable. The detailed feedback is more than enough, and the word-tap feature has helped me build my vocabulary so much faster!" Minh Khanh, High School Student
"I’ve hit 7.0, so I had to come back and thank Keraft’s speaking practice. Speaking really does need a partner to build reflexes. Keraft is online 24/7, which is perfect for my irregular study schedule, and the personalized learning path kept me focused on the skills I actually needed to improve." Minh Chien, University Student
"I bought the unlimited plan to support students who study and self-score at home. I was pleasantly surprised that the AI handled things better than I expected and made the students much more independent. The AI Q&A feature and CEFR-aligned assessments are genuinely helpful and worth it!" Trung Hieu, English Center Teacher
