• Data Privacy Concerns
  Using an unofficial third-party service to process conversations raises questions about how user data and conversation history are stored, used, or shared.
• Limited Transparency
  It may be unclear which underlying AI model version is being used, how up-to-date it is, or what modifications have been made to the base model's behavior.
• Potential Hidden Costs or Ads
  Free-to-use AI wrapper sites often monetize through ads, premium upsells, or data collection, which may not be clearly disclosed to users upfront.
• Lack of Official Support
  Unlike official AI platforms, unofficial wrapper sites may lack dedicated customer support, regular updates, or accountability if issues arise.
