The AI Visibility Checker shows if ChatGPT and Gemini name you.

An AI visibility checker is a tool that asks AI assistants the questions a buyer would ask and reports whether a business is named in the answers, which rivals are named instead and which sources the assistants cite. RankX AI’s free checker asks three buying questions on ChatGPT and Gemini and reports all six answers.

Yes, for three reports per email address, with no account. Each run costs RankX AI real money, six live answers from the consumer apps and the analysis of each, so the checker verifies your address before it runs and emails you the link to your report. A website checked in the same market within 24 hours reuses that result, and a daily ceiling pauses the tool rather than running up a bill.

The AI Visibility Checker reads your homepage to learn what the business sells, writes three prompts a buyer would ask when looking for that kind of business, and asks each one on ChatGPT and Gemini. For each of the six answers it reports whether your business was named, which businesses were named instead, and which websites the assistant cited as its sources.

Because a question that names the business makes a mention certain and tells you nothing. A buyer who already knows your name can find you; the question that matters is whether an assistant suggests you to someone who does not. The AI Visibility Checker drops any generated question that contains your business name or your domain, and it needs at least two clean questions to run.

From the ChatGPT and Gemini consumer apps, the ones buyers use. Answers there arrive with their sources: in RankX AI’s checks in August 2026, every ChatGPT answer and 79% of Gemini answers carried citations. The citations are half of what this checker shows.

ChatGPT and Gemini. They are the two assistants whose consumer-app answers RankX AI reads together with their cited sources, and every extra assistant adds cost to a free run, so the free check spends its budget where the sources are. The RankX AI product itself tracks ChatGPT, Claude, Gemini, Grok, Perplexity and Microsoft Copilot, on a schedule, chosen per website.

Because assistants rarely answer the same way twice. SparkToro’s 2026 study of 2,961 runs found under a 1 in 100 chance that an assistant returns the same list of brands in any two answers. Within 24 hours the checker reuses its result for the same website and market, so you see the same report; after that, a new run is a new sample. A single reading is a snapshot, and only repeated checks of the same questions make a trend.

Because ChatGPT and Gemini search the web differently, read different sources and weigh them differently. The cited sites in the report show this directly: the two assistants often lean on different directories, review sites and articles for the same question. A business named by one and missing from the other is usually present on the sources the first reads and absent from the sources the second reads.

It means that on this run, for these three questions, neither assistant suggested your business. Assistants answer the same question differently on different days and for different people, so one reading is a snapshot rather than a verdict. It is still worth acting on: the businesses named instead are your benchmark, and the sites cited show who the assistants currently trust for your market.

RankX AI did not get a usable answer for that question on that assistant, because the assistant did not respond in time or its answer could not be analysed. That answer counts neither way. The AI Visibility Checker reports “named in 1 of the 2 answers we could read” rather than “1 of 3”, because an answer that could not be read is not evidence about your business.

Start with the cited sites in your report. Assistants recommend businesses that the sources they read already mention, so a listing, a review or an article on those sites is the most direct route into an answer. Then make sure the assistants can read your own site at all, which the AI Crawler Access Checker tests, and that your homepage says plainly what you sell and where. The measured playbook for ranking in ChatGPT covers the rest.

The AI Visibility Checker runs in twelve markets: the United Kingdom, the United States, Ireland, Canada, Australia, New Zealand, Germany, France, the Netherlands, Spain, Italy and India. The market decides where the questions are asked from and the language they are written in, and the list is fixed, which is one of the controls on what each free check costs.

The free checker is one snapshot: three questions RankX AI writes, on ChatGPT and Gemini, once. The RankX AI visibility tool is the continuous version, an AI visibility tracker doing the job AI brand monitoring tools do: it asks the prompts you choose across ChatGPT, Claude, Gemini, Grok, Perplexity and Microsoft Copilot, every 1, 3, 7, 14 or 30 days, keeps every answer and turns brand mentions, rivals and citations into a trend you can defend.

Google AI Overviews have their own free tool. The AI Overview Checker looks at Google search: whether one keyword triggers an AI Overview and which pages it cites. The AI Visibility Checker looks at the assistants people ask directly and whether they recommend your business when a buyer describes what they need. The two are built from different sources, so doing well in one does not predict the other.

Your report stays at its link for twelve months, and anyone you share the link with sees the same page. The answers are fixed at the time of the check; to see whether anything has changed, run the check again or track the questions in the RankX AI product, which keeps every answer so a change shows up as a trend.
