When your buyers ask an AI, does it name you?

See how often Claude, GPT, Gemini and Perplexity name your company.

Enter a work email and a domain. The audit runs in two halves. The first opens the report page on its own after a short wait: a score out of 100 for whether an AI can read your home page and whether it is allowed to. The second takes a few minutes. It derives the questions the domain's buyers ask an AI, puts each to Claude, GPT, Gemini and Perplexity with web search on, and reports the share that named the domain.

We filled this from your email. Change it if the audit is for another site.

Your audit runs whether or not you tick the box. We do not share your address with anyone else, and every email has a one-click unsubscribe. Stan Berteloot may send you a LinkedIn connection request. Read our privacy statement.

We email you the report link, and if you leave the box unticked and your address is not at the audited domain, we ask you to confirm the address before we send it.

How it is measured

Why we ask every question three times

AI assistants give different answers to the same question from one run to the next. One run is a sample, not a measurement. So we ask each question three times on each of Claude, GPT, Gemini and Perplexity, twelve runs. We report how often your domain was named. The number is a frequency, never a ranking position.

In January 2026, SparkToro ran 2,961 prompt tests across ChatGPT, Claude and Google AI with 600 volunteers. SparkToro is an audience research company co-founded by Rand Fishkin, who also co-founded Moz. A prompt had under a one in a hundred chance of returning the same brand list twice. The top names held steady, in 55 to 77 percent of responses. In Fishkin's words: "Any tool that gives a 'ranking position in AI' is full of baloney."

Questions

Before you run it

What exactly do you measure?

We measure two things. First, a score out of 100: can an AI read your home page, and may it? Each check is a rule applied to fetched bytes, so a page scores the same twice. The robots file and the server are scored separately. Training crawlers are scored nowhere. Second, four questions from your page each run three times on Claude, GPT, Gemini and Perplexity, 48 answers. We count the answers naming your domain and list every other source.

Why does the frequency change if I run it again?

AI answers are probabilistic. That is why each question runs twelve times. Two audits a day apart can land on different frequencies for the same domain. That is expected. The frequency is the honest number.

Which platforms do you check?

We check four: Claude, GPT, Gemini and Perplexity. Each runs with live web search on. So every answer comes from a search made when you run the audit. We check no other platforms.

How many questions do I get?

Four. We read your home page and write four questions your buyers would ask, so you do not pick them. Each runs three times on Claude, GPT, Gemini and Perplexity. That makes 48 answers.

What does it cost?

Nothing. You need no card and no account. Your work email is where we send the report link. Ticking the box is optional. It signs you up for emails from Nytro AI by Nytro Marketing.
