Short answer: an AI chatbot makes things up when it is asked something it has no reliable source for and is allowed to answer anyway. To stop that, limit it to your own content, make it show where an answer came from, and make it hand the conversation to a person whenever the content does not clearly cover the question.
Why do AI chatbots make things up?
A language model writes the most likely next words, so without a reliable source it can still produce a confident, fluent answer that is wrong, such as a refund policy you do not have. It is not a rare glitch; it is how the technology behaves when it is given no limits.

How do I stop an AI chatbot from making things up?
Limit it to your own content, make it show its source, let it hand over when unsure, keep personal questions away from it, mask sensitive data, check every answer before it is sent, and test it often. These seven safeguards work together, and none of them needs a technical team.
- Answer only from your own content. Give the assistant your pages, help articles, documents and written question-and-answer pairs, and tell it to use nothing else. In Frosvo the assistant answers from what you give it and shows the source it used. See the AI assistant.
- Let it say "I don't know". The assistant should hand the conversation to your team when your content does not support an answer. In Frosvo you can set it to answer only when the knowledge base clearly covers the question; anything else goes to a person, and costs nothing.
- Keep personal questions away from it. Questions about a customer's own account, money or orders need a person with access to the real data. Frosvo hands those over.
- Mask sensitive data. Card numbers, bank account numbers, passwords, PINs and keys should never reach a model. Frosvo replaces them with placeholders before the model sees a conversation.
- Check every answer before it is sent. An answer that reveals the assistant's instructions or links to a website you never gave it should be held back. Frosvo checks each answer and sends the chat to your team if one fails.
- Write good source content. The best protection is a clear, current knowledge base. Short articles that answer one question each give the assistant less room to improvise. Read how to prepare knowledge for AI customer support.
- Test it, then keep testing. Ask it the questions you fear: a refund you do not offer, a feature you do not have, a request to ignore its rules. Frosvo's safety check runs known attacks against your assistant and shows how each was handled, and test questions let you check answers before customers do. See the assistant safety check.
How do I monitor the assistant once it is live?
Review the answers it gave and mark the bad ones, read the knowledge gaps it could not answer, check the handover reasons and set a monthly AI budget. Looking at real conversations every week shows where the content is missing long before a customer complains.
- Review the answers the assistant gave and mark the bad ones.
- Read the knowledge gaps: the questions it could not answer.
- Check the reasons for handovers, so you know whether it hands over too much or too little.
- Set a monthly AI budget so costs stay predictable. See AI budget and usage.
Should I tell customers it is AI?
Yes. Label the assistant as AI and tell visitors they can ask for a person. Some laws require this, and it is the honest thing to do either way. Frosvo's widget labels the assistant's messages as AI by default and keeps a person one click away.

What is the one rule to remember?
An assistant is only as trustworthy as the content it is limited to and the person standing behind it. Keep the knowledge base current, keep a human reachable, and test the assistant regularly, and it will save your team hours without putting words in your mouth.
