The project reveals a persistent gap in mainstream edtech: platforms optimize for beginners while leaving advanced learners underserved. AI-powered corrections, spaced repetition flashcards, and customizable learning paths demonstrate how focused tools can outperform broad platforms by addressing specific user needs.
