Which ServiceNow capability allows you to provide knowledge articles, via a conversational messaging interface?

Agent Assist helps human agents by suggesting relevant knowledge articles, but it does not provide articles directly to end-users via a conversational interface.

Virtual Agent is ServiceNow's AI-powered conversational bot that allows users to get information, resolve common issues, and access resources like knowledge articles through a chat interface. It automates common support tasks and improves the self-service experience.

Now Messenger is a real-time messaging tool for collaboration between users, not an automated system for delivering knowledge articles via a conversational bot.

"Instance Chat" is a generic term and not a specific ServiceNow capability designed for automated knowledge article delivery through a bot.
