  Free online PDF tools typically impose file size restrictions, which can be a problem when working with large or complex PDF documents.

  Using an unofficial third-party service to process conversations raises questions about how user data and conversation history are stored, used, or shared.

  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.
