    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
