    AI-generated flashcards and quizzes may occasionally produce inaccurate or poorly worded questions, requiring users to review and manually correct the generated content.

    Advanced features may be locked behind a paid subscription, which could be a barrier for students on tight budgets who need full access to the platform's capabilities.
  • Internet Dependency
    As a web-based application, Cubrain requires an internet connection to function, which limits its usability in offline environments or areas with poor connectivity.
