# ChatGPT and Perplexity show different information about our business in Ingolstadt, Gemini gets it all right, why?

A business in Ingolstadt notices a clear accuracy gap between Gemini, ChatGPT, and Perplexity when it comes to its own information.

Out of curiosity we checked our business in Ingolstadt across several AI tools. Gemini got the address and opening hours exactly right, while ChatGPT and Perplexity each had some details that were outdated or simply wrong.

What explains such a clear difference between the individual AI tools?

That difference is real, and it was systematically measured in SOCi's 2026 Local Visibility Index, a study of nearly 350,000 locations across 2,751 brands using more than 120 metrics. Gemini averaged 100 percent profile accuracy, because it reads data directly from Google Maps and the Google Business Profile, while ChatGPT and Perplexity each landed at only 68 percent, noticeably behind, because they assemble their profiles from various third-party sources.

The same study also shows how rarely AI tools actually recommend a given business at all, ChatGPT did so for only 1.2 percent of studied locations, Perplexity for 7.4 percent, Gemini for 11 percent, compared with 35.9 percent for appearing in the Google local three-pack's local search results. SOCi accordingly describes AI visibility overall as 3 to 30 times harder to achieve than a good ranking in classic local search.

For your business, the upshot is that an accurate Google profile alone doesn't guarantee accuracy on ChatGPT or Perplexity, since those tools pull in their own, independent sources. Illia BizTech's [AI Visibility Report](https://illia-biztech.de/en/ki-sichtbarkeitsbericht) puts the individual AI tools side by side and shows how accurately your business in Ingolstadt appears in each.
