About Gemini coverage. Gemini responded to only 33 % of our 759 test runs — the rest were blocked or failed. Direct comparisons against ChatGPT and Claude should be interpreted with caution. (32.9 %).

Is your company mentioned?

Find your company.

Search by company name or domain. See how often AI models mention you, in what contexts, and what each model actually said.

The index only contains companies and domains that ChatGPT, Claude or Gemini actually mentioned across our 253 prompts. This is not a Brønnøysund-style company register.

Three things that surprised us

Findings from 2,277 runs across 11 industries.

Claude hallucinates 64 % more than ChatGPT

Claude has higher average hallucination severity (0.82) than ChatGPT (0.50) — and twice as many serious cases.

Twelve domains get 67 % of all the credit

LinkedIn, proff.no and Wikipedia dominate source citations. Specialised Norwegian press and trade publications are underrepresented.

0 correct citations across 23 prompts

In some industries (e-commerce, recruiting) AI models never cite the right Norwegian players — a fast GEO opportunity.

Who lies the most?

Average accuracy, hallucination severity and brand-cited rate per platform. Higher accuracy is better (0-3). Lower hallucination is better (0-3).
