Which ServiceNow capability provides assistance to help users obtain information, make decisions, and perform common work tasks via a messaging interface?

Agent Workspace is a unified interface for IT agents to manage multiple requests and incidents, not a user-facing messaging interface for self-service.

While Virtual Agent is a type of chatbot, 'Chat bot' is a generic term, and Virtual Agent is the specific ServiceNow product providing this capability.

ServiceNow Virtual Agent is an AI-powered conversational interface that provides automated assistance to users, enabling them to find information, resolve common issues, and complete tasks directly through a messaging or chat window.

Knowledge Chat is not a standard ServiceNow capability; while knowledge articles can be delivered via chat, 'Knowledge Chat' itself is not the overarching capability.

Now Support (formerly HI Service Portal) is a portal for ServiceNow customers to manage their ServiceNow instances, not a general user assistance messaging interface.
