Voice agent, chatbot or AI assistant: the difference that matters
A chatbot answers questions, an assistant helps a person do their work, and an agent finishes a defined job on its own. The practical test that separates them takes about a minute: ask whether the thing can act inside your systems, whether it writes down what it did, and whether it stops when it is out of its depth. Anything that fails those three is a chatbot, however it is described in the deck.
