Novel approach for language learning: AI-based tutor guides the learner → toward advanced mastery.
Focus on Personalization — tailor practice sessions → to each learner's current skills and interests.
How personalization is achieved:

• Authentic material — practice is based on arbitrary content, which the learner chooses from any source.
• Continual assessment of learner's knowledge — helps the AI tutor select the best possible exercises for the learner.
