  Compared to more feature-rich conversion tools or scientific calculators, Unitly may lack advanced functionality such as custom unit definitions, API access, or integration with other tools and workflows.

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

• Lack of Official Support
  Unlike official AI platforms, unofficial wrapper sites may lack dedicated customer support, regular updates, or accountability if issues arise.
