  • Internet Dependency
    As an online tool, its functionality is dependent on a stable internet connection, which may not be accessible to all users at all times.
  • Privacy Concerns
    Uploading files to an online service may raise privacy and security concerns, especially if the documents contain sensitive information.

    Compared to desktop applications, PDF Joiner may lack advanced features such as detailed editing or OCR, which can be necessary for professional use.

  • No Installation Required
    Being a web application, it can be used directly from a browser without downloading or installing any software.

Possible disadvantages

  • Uncertain Reliability
    Third-party GPT wrapper websites often depend on underlying API access that can be unstable, rate-limited, or discontinued without notice, affecting consistent availability.
  • 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.
