When someone asks ChatGPT, Claude, Perplexity or Gemini for the best in your category — do they name you? Find out free. See the receipt.
RadRank is the neutral scoreboard — the "MRC of AI answers." Every other AI-visibility tool has the same conflict: the company that sells you the optimization also controls the score. We don't. We measure; we don't operate what we grade; and we show you every operator who can help — us included or not.
We disclose the exact prompt set, the engines probed (ChatGPT · Claude · Perplexity · Gemini · AI Overviews), the sampling cadence, and the citation-extraction rules. You can add your own real, short buyer-intent prompts. Every score expands to the raw evidence — the exact prompt, the model, the date, the verbatim answer, and the brands it named. If you can't inspect the number, it's marketing, not measurement.
