    While cost-effective compared to traditional methods, the subscription fees can still be significant for some users, particularly small businesses or individual creators with limited budgets.
  • Learning Curve
    Although designed to be user-friendly, there is still a learning curve associated with mastering the platform's features and capabilities.

  • Dependency on Technology
    Users are dependent on the availability and reliability of the Synthesia.io platform, and any technical issues or downtime could disrupt video production schedules.
  • Ethical and Privacy Concerns

    LeetCode mainly focuses on algorithm and data structure problems and doesn't cover other technical aspects like system design, databases, or front-end development as comprehensively.
  • Variable Quality of Community Solutions
    While the community is active, the quality of user-contributed solutions and explanations can vary significantly, and some may not follow best practices or be optimal.
  • Platform Performance Issues
    Some users report occasional performance issues such as slow loading times or glitches during peak usage times, which can be frustrating during practice or contests.
  • Overemphasis on Coding
