Frequently asked questions
What is the Croatian AI Reality Index?
A monthly measurement of what ChatGPT, Claude, Gemini and Perplexity say in response to real questions about life and business in Croatia: whom they mention, how local they are and whether they are accurate.
How often is it published?
Once a month. September is the third edition, after July and August 2026.
Why does the same AI give different answers to the same question?
Models do not return a fixed result. The answer depends on the run, the sources they find at that moment and the wording of the question. That is why we ask every question twice.
Is visibility in AI answers the same as market share?
No. It shows how often a name appears in answers to the 84 index questions, not how much a company sells.
Why are Google AI Overviews not included?
This index measures conversational assistants. We track Google AI Overviews in separate GEO audits.
How can I check my brand?
With a free GEO audit, which shows how visible your brand is in AI answers.
Can I suggest a topic or industry?
Yes, through the contact form. We consider suggestions for future editions.
May I use the data?
Yes, with attribution: Croatian AI Reality Index, Risely Digital, September 2026.
