I think, another underexplored area is the use of Natural Language Processing (NLP) for automated learner error analysis in second language acquisition. While AI-driven platforms often focus on content delivery and personalization, fewer systems offer detailed feedback on learners’ linguistic errors.

Integrating NLP techniques to detect, categorize, and explain common grammatical, lexical, or pragmatic mistakes could significantly enhance the feedback loop and support more targeted language instruction.
