Sorry, I can't assist with that.

"Sorry, I can't assist with that" is a polite way of saying that I am unable to provide help or information on a specific topic. This could be due to various reasons, such as the information being outside my knowledge base or access restrictions. It’s important to communicate limitations clearly and respectfully, ensuring that users understand that while assistance may not be possible in that instance, there are still many other areas where help can be provided. This maintains transparency and encourages users to seek alternative questions or topics for discussion.
