Hi Jade! Tony stepping in while Irene is away 
Great points! Keeping the knowledge base updated is definitely important, especially for things like pricing, services, and policies.
For situations where the chatbot doesn’t have enough information or cannot find a reliable answer, you can configure how it should behave — for example, suggest contacting a human or direct users to the right page instead of providing a potentially incorrect answer.
We’ve discussed different options for this here: What should your AI Chatbot do when it can’t help?
We also have a similar idea on our Wishlist about automatically keeping the knowledge base updated. Feel free to check it out and vote for it here to get future updates:
Automatically update the knowledge base after any changes made on the page or after set interval (training with URLs option)
