What is a software application that allows for online chat conversations via text or text-to-speech?

A software application that allows for online chat conversations via text or text-to-speech is known as a chatbot. Chatbots are designed specifically to facilitate automated conversations with users, simulating human interaction through text or voice responses. They utilize artificial intelligence to understand user inputs and provide relevant responses, making them highly effective for customer service, information retrieval, and other interactive applications.

While data analyzers serve a different purpose—analyzing and interpreting data—web browsers function as gateways to the internet, enabling users to access web content but not facilitating chat interactions in themselves. Email clients are applications used for sending and receiving emails, which, unlike chatbots, do not support real-time conversation. Hence, the unique functionality of chatbots makes them the correct answer for enabling online chat conversations efficiently.
