Terms of Service

The service

This platform provides adaptive language learning: placement tests, adaptive practice, error attribution, spaced review, listening training, and AI conversation practice. Knowledge points and questions are AI-assisted and human-reviewed but may still contain errors; rely on proper dictionaries and textbooks. JLPT listening scaled scores are approximate.

AI technology

We use third-party generative AI models to produce conversations, content, and speech. Output may be inaccurate or unnatural; please verify before relying on it (for example, for official exams or workplace language).
