In depth
Conversational AI is software whose main job is a back and forth with a person, whether that happens in a chat window, a text message, or a phone call. You speak or type in your own words, the software works out what you are trying to get done, and the next reply still makes sense after several turns. Menu bots from an earlier decade could only follow buttons and exact keywords, so a question asked a slightly different way would stall. A current system can stay with an open question, move when you change the subject, and remember what was already said in that same session.
You will usually meet it in a few familiar spots. A chat box on a website can answer a question about hours, a service, or a time to come in. A text thread can continue a conversation that started on the site, on the phone a person already carries. A voice system can take an incoming call, ask what is needed, and either finish a simple request or pass the caller to someone on the team. One model often sits under all three, with different limits on speed and care, because a spoken reply has to arrive quickly and a written one can take a moment longer.
The talk is only half of what matters. Software that sounds natural and cannot look up the right fact, reserve a time, or write the note into the file you already keep will make the person on the other end repeat themselves. Before anyone spends time on tone, decide which questions it may answer from your own documents, which actions it may take, and which moments it must hand to a person who can see the whole situation.
