How we measure
- Every week we ask ChatGPT, Gemini, Claude and Perplexity the questions buyers ask in each industry of the AI Index.
- We record the sources each answer cites. For each industry we keep the 15 most cited domains, so smaller sources are not counted here.
- Customer data is never used. These numbers come only from questions Variask runs itself.
