    Despite high accuracy, there is always a possibility of errors or misinterpretations that could lead to misinformation if not properly reviewed by users.
  • Privacy concerns
    Processing sensitive information through AI services raises privacy concerns, especially if confidentiality and data protection policies are unclear or insufficient.
  • Limited domain expertise
    The AI might struggle with highly specialized or technical content, which could lead to inadequate summarization or misunderstanding of complex topics.
