Accountancy & Tax Advisory
Accountants, auditors and tax advisers serving Gibraltar businesses and residents.
What each assistant answered
The same question, put to four AI assistants with live web search. Each column is that assistant’s own answer, in its own order, in its own words, not a filtered version of it. They rarely agree, which is the point: being first for one is not being first for the others. Where a column reads “no answer”, the request to that assistant failed; that is not the same as it naming nobody, so we say which it was.
