Hallucination
Term from the world of AI visibility – explained simply by the GeoStars team.
A false or invented statement by an AI system – for example incorrect brand information. Monitoring uncovers hallucinations about your own brand before they reach customers.

Why AI systems hallucinate
Language models produce text by probability, not by truth. When solid knowledge is missing, the model fills the gap with something plausible-sounding – with invented prices, features or even company names. For brands that's doubly risky: the AI can claim false things about you or portray you in comparisons with invented weaknesses.
What brands can do about it
The best insurance is unambiguous facts that are consistent everywhere: current prices and features on your own site, in llms.txt and in structured data, consistent information in directories and press. The clearer the facts on the web, the less often the model invents something. Only monitoring gives you control: with daily measurements and Sentiment analysis, GeoStars shows what AI systems actually say about your brand.
