# What is Virtual Agent?

Also called conversational agent, chatbot.

A virtual agent is a customer facing conversational system that handles inquiries in chat, voice, or messaging, resolves the requests it is equipped for, and routes the rest to a person. The term comes from contact center software and predates language models. Modern virtual agents usually combine retrieval from a knowledge base with the ability to act on business systems.

The lineage matters. Early virtual agents matched utterances against a hand built intent list, so anything unanticipated fell through immediately and visibly. Model based versions handle open phrasing and follow up questions, but introduce a different risk, which is answering confidently from something that is not in the source material. Both generations depend on a defined escalation path to a person.

Organizations measure virtual agents on containment, meaning the share of conversations fully resolved without a person, alongside answer accuracy and satisfaction. Common scope includes order status, account changes, access and password issues, appointment changes, and policy questions. Billing disputes, cancellations, and emotionally charged conversations are usually routed to a person deliberately rather than contained.

Virtual agent, chatbot, virtual assistant, and conversational AI are used interchangeably in vendor material. Chatbot generally implies a narrower scripted system and virtual agent implies the ability to complete an action rather than only answer, but neither implication is reliable. The list of actions a product can actually take says more than the label it carries.

Inside a company the same technology is usually called an assistant or an agent. Virtual agent specifically implies an outside audience, which raises the bar on tone, accuracy, and escalation. Where support volume is handled by a broader mix of drafting, triage, and direct answering, the arrangement is usually described as AI in customer support.

## In practice

An online store's virtual agent handles the where is my order question. It asks for an order number, looks up the shipment, gives the carrier status in plain language, and offers to resend the confirmation email. If the parcel is marked delivered but the customer says it never arrived, it stops, apologizes, and opens a ticket for a human agent with the full history attached.
