A novel approach to language learning: AI-based tutor guides the learner → toward advanced mastery.
Personalization: each practice session is tailor-made — for each learner's current interest and skill level.
How personalization is achieved:

• Authentic material — practice with arbitrary, real content, which the learner can choose from any source.
• Continual assessment of learner's knowledge — lets the AI tutor select the most suitable exercises for each learner.
