# Knowledge Base Explained
There is a limited amount of room and so the system needs to search through the knowledge base to find relevant information that might help a user's question.
Technical overview of the AI chatbot
The knowledge base is split up into multiple sections that make it super easy to add the information about your business.
It's important to note that more data is not always better. We recommend that you only add relevant information that helps provide context to the overall conversation.
