AI hallucination
An AI hallucination is a convincingly worded but false or fabricated statement by an AI system. Language models compute plausible phrasings — where a reliable source is missing, they guess. Risky for businesses: invented opening hours or services look deceptively real.
Hallucinations stem from how large language models work: they compute which phrasing is most likely — not which one is documented. Where reliable information on a question is missing, the model fills the gap with something plausible. The result sounds confident but may be entirely made up: a wrong phone number, a closing day that never existed, a service you do not offer.
The most effective remedy from a business's point of view: give the AI reliable material. An up-to-date website as the central source of truth, consistent contact details everywhere and structured data that labels facts unambiguously. Many AI systems consult real sources before answering — a business that presents itself clearly and machine-readably there lowers the risk of being guessed at instead of reported correctly.
For your business that means checking regularly what assistants say about you — opening hours, prices, services. If wrong details appear, the cause is often an outdated or contradictory source. The fix happens not inside the AI but at the source: bring your website, Google profile and directories to the same, current state.

Frequently asked questions.
How do I keep opening hours and contact details up to date everywhere?
The core principle: one source instead of many copies. If opening hours, address and phone number are maintained in one central place, and the website, structured data and machine-readable formats automatically serve the same state, nothing can drift apart. That is exactly what a website built as a single source of truth delivers: change it once, current everywhere.
Externally, the effort stays manageable: above all, keep your Google Business Profile and the most important directories up to date — with exactly the same details as on your website. For seasonal hours, a fixed routine helps, say at the start and end of the season. The background: contradictory details are the most common reason AI assistants tell people wrong things about a business.
Why does an AI recommend me with the wrong number or opening hours?
Because AI assistants mostly pull their facts from map and directory data. If your details are inconsistent or outdated there — an old number, a wrong opening hour — the AI picks up exactly that and states it confidently as an answer.
Directories also often copy from one another, so a single error spreads across several platforms. For your business, that means a small inconsistency in one place can end up as a wrong answer in several AI responses.
How do I find out whether an AI gives wrong information about my business?
Regularly ask the major AI assistants about your own business — services, opening hours, prices, and how you compare to competitors — and check the answers for accuracy. Without this check, wrong information often only surfaces when customers arrive with false expectations or never get in touch at all.
