While there are a variety of interface brands, to date, there are two main categories of conversational interfaces; [[voice command device|voice assistants]] and [[chatbot]]s.
==Voice-based

Siri allowed users of iPhone to get information and complete actions on their device simply by asking Siri. In the later years, Siri was integrated with Apple's [[HomePod]] devices.

This information can be generic in nature such as the Google Assistant chat window that allows for internet searches, or it can be a specific brand or service which allows the user to gain information about the status of their various accounts.
