How we measure

Read the full method
  1. We ask 5 AI tools

    We ask ChatGPT, Claude, Gemini, Perplexity and Google AI Overviews what people ask when they choose software.

  2. We count the brands they name

    For each tool, a brand’s score is the share of answers that name it. The five scores are averaged, so no single tool outweighs the rest.

  3. We repeat every month

    Same tools, same questions. If a question or a tool changes, we say so.
