What AI tools answer when someone looks for citizenship advisory services

In 35 of 98 responses, AI does not cite any advisory firm

This is the trait separating this niche from the others we measure. AI barely names companies here: 1.4 mentions per response, against three or four in other sectors. In 35 of the 98 responses, 36%, it explains the process, recommends checking reputation and names no one. In ChatGPT, this happens in 13 of 25.

When it does name firms, it still does not choose a winner. Cidadania4u is the most cited, in 32 of 98 responses, and second place, Nostrali, appears in 15. None of the 20 reaches half the responses.

Appearing is one thing; being the first name is another

AI almost never answers with just one advisory firm: it averages 1.4 names per response. That is why where a name appears matters as much as appearing at all. Nostrali opens the list most often, with an average place of 1.4. Velloso Cidadania is at the other extreme among the higher-volume firms: it appears in 11 responses and enters at 2.0th on average, after the reader has already seen other names.

For firms in the middle of the table, this is where the difference lies between being considered and merely mentioned. A list has a beginning, and anyone arriving at its end competes with names the reader has already seen.

Each tool has its own ranking

The same advisory firm changes in size depending on where the question is asked. Cidadania4u is the strongest case: it appears in 56% of Google responses and 4% of ChatGPT responses. For anyone outside the top positions, this means there are tools where they can compete and tools where they cannot.

Being read by AI almost guarantees being cited by it

In 59 of the 98 responses, it is possible to see which sites the tool consulted. There were 137 different sites, and the most used of all is cidadania4u.com.br, Cidadania4u’s site, in 7 of the 59. Among the ten most used, 8 are sites of the advisory firms measured and 2 are outside sites, such as iogringo.com.br and reclameaqui.com.br.

What the tool reads also appears in what it writes: when the advisory firm’s site was consulted, its name appeared in the response 82% of the time. When it was not consulted, the name appeared in 3%. It is worth separating what appears in the text without competing for the sale: Correio Braziliense, Eurodicas and Guia da Itália are a content portal and newspaper, while Reclame Aqui is a reputation site. They were measured and remain outside the table because they do not sell the process.

The question slice has little effect at the top

The 25 questions were written in five slices: general recommendations; country and route of the process; stage (certificate, consulate, comune); questioner profile; and informational questions about price and timing. The leading names recur in almost all of them.

What changes from one slice to another happens in the middle of the table, not at the top. For firms outside the leading positions, this is where there is an opening: a country or stage of the process in which AI already cites other names.

How we measure

• We asked the 25 questions in 4 tools, once each, in September 2026. That would yield 100 responses; we retained 98. In Perplexity, 23 of 25 were retained: 2 captures failed. Each question was asked in a clean window, in a temporary conversation without history, from an IP in Brazil. We saved every screenshot.
• No question names an advisory firm. All ask for recommendations, as someone asks before hiring one.
• We count only when AI writes the advisory firm’s name in the response. When the name appears only in the list of sites consulted, it does not enter this count: that is something else, measured separately in section 04.
• We count only what the tool wrote. Site cards, videos and map listings around the response are excluded because AI is not choosing the name there.
• The names in the table came from the responses themselves. We did not begin with a ready-made list, so no outside advisory firm ‘should’ be there: if it was not cited once, it does not appear.
• Capture ran more than one pass per question. Only the first entered the count, which is the single pass used in the other studies. Mixing repetitions would inflate the figures and break comparison between studies.
• Two Perplexity responses stopped at a registration wall. They exist as captures and measured nothing, so they were removed from the numerator and the denominator.

What this study does not say

• Nothing about service quality. What is measured is what AI tools answer, not who has the best acceptance network or the lowest fee.
• Nothing about how much each thing is searched. The 25 questions reflect how decision-makers ask, not a sample weighted by search volume.
• Nothing about what AI answers for you. Responses vary with the preceding conversation, region and day. This is a September 2026 snapshot in a clean window.
• Nothing about how to change this result. This material measures; it is not an action plan.
