![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Use the Topic Properties tab to identify a topic and how it's used. You can control who uses the topic and what channels it can run in.
If you enable NLU/Keyword in Virtual Agent settings, the topic Properties tab includes fields for identifying the NLU model and intent for the topic.

For more information, see [(Legacy) Create a topic form](https://www.servicenow.com/docs/x2wQSfqiXzXCsMBj2I7t0w "The Create a topic form is used to set the properties for a new conversational topic for Virtual Agent.") and [(Legacy) Creating a Virtual Agent NLU topic](https://www.servicenow.com/docs/BPAFQKNMzNdsOUPkr4av~A "Use Virtual Agent Designer to create and modify Virtual Agent topics (conversations). Build your topic to meet a specific objective or goal, such as fulfilling a user's request or helping a user complete a task.").
