Creating knowledge bases

Knowledge bases provide the unstructured data that assistants use to generate responses to user questions.

A knowledge base comprises one or more data sources. Data sources added to a knowledge base are indexed for use in assistants. You can reindex sources that have been updated, either manually or by scheduling a synchronization with the data source. For more information, see Indexing knowledge base data sources.

You can have five knowledge bases per assistant.
