Traditional language apps often provide the same sequence to all users. An adaptive tutor could adjust difficulty, topics, and teaching methods based on daily performance.
The tutor would track mistakes, response times, and engagement to customize future lessons. It would remember vocabulary struggles and grammatical weak points.
Serious language learners would pay a subscription for the personalized approach.
Start with basic vocabulary adaptation, then add grammar and conversation adjustments.
Risk: Requires significant training data to outperform existing apps.
