How to stop a chatbot from making up answers
Sources, limits and controls to reduce incorrect replies and promises your business can't keep.
In a nutshell
There's no absolute guarantee that an AI will never be wrong. But you can greatly reduce the risk by limiting sources, authority and scope, and by handing off when reliable information is missing.
Identify where a mistake hurts
Not every answer carries the same risk. Getting opening hours wrong is annoying; inventing a price, availability or a contractual condition can create a serious commitment.
Rank topics by impact and reserve the most sensitive ones for verifiable sources or human review.
- Low: general guidance.
- Medium: commercial policies.
- High: payments, availability or professional decisions.
Use authorized sources
The assistant should answer from approved content and keep it apart from general knowledge. If two documents contradict each other, the fix is to correct the source, not to ask the AI to choose.
Sources that change need frequent updates or an integration that looks up the data in real time.
- One current version per topic.
- Date and owner.
- No unnecessary internal data.
- Search and answer tests.
Limit its authority
Spell out what it may state and what it must confirm. When it finds no backing, the right answer may be to say so and offer that the team continues.
Avoiding an answer is better than creating false certainty.
- Don't estimate stock.
- Don't create discounts.
- Don't confirm appointments without a calendar.
- Don't give regulated advice.
Ongoing monitoring
Review low-confidence replies, reopened conversations and team corrections. Turn every repeated finding into an improvement to the source or to the handoff rule.
Volga records the conversation's path and lets you pause the AI. Human supervision remains part of the system, especially in high-impact processes.
- Weekly sample.
- Adverse cases.
- Alerts for sensitive topics.
- Clear escalation path.
Frequently asked questions
Questions about this guide
Can you completely eliminate the risk of a wrong answer?
No. It shrinks with controlled sources, limits, validations and human handoff, but important processes always need supervision proportional to the risk.
Do more documents always improve the answer?
No. Many repeated or contradictory documents make search worse. What matters more is that the source is clear, current and authorized.
